Серед усіх культурних рослин, що вирощуються у світі, кукурудза поряд із іншими зерновими займає одну з провідних позицій. Провідна роль у цьому належить селекційному прогресу у розвитку та врожайності кукурудзи, який неухильно просуває цю культуру дедалі вище у рейтингу найуспішніших культур для вирощування. Для реалізації біологічного потенціалу культури ПП «Каштан» запропоновано сортооновлення - гібрид кукурудзи СИ ПАНДОРАС потенціалом врожайності 14-15 т/га та захист посівних площ від бур’янів гербіцидом Елюміс 105 OD.
Among all cultivated plants grown in the world, corn, along with other cereals, occupies one of the leading positions. The leading role in this belongs to the selection progress in the development and yield of corn, which steadily promotes this crop higher and higher in the ranking of the most successful crops for cultivation. To realize the biological potential of the culture of PE "Kashtan" proposed varietal renewal - maize hybrid SI PANDORAS with a yield potential of 14-15 t/hectare and protection of sown areas from weeds with herbicide Elumis 105 OD.

Doctor of Philosophy

David B. Mengel
Corn (Zea mays) is an important cereal crop in Kansas primarily used as livestock feed for cattle in the feedlots, and there has been increased use of corn for ethanol production as well. According to the USDA National Agriculture Statistics approximately 1.7 million hectares of corn is planted each year in Kansas, with an average yield ranging from 5,750-7,750 kg ha[superscript]-1 within the last five years (2005-2009). With this variability in yield and volatility of crop and fertilizer prices over that same period, it seems logical that optimum nitrogen or N rates may vary. A series of 14 field experiments were conducted across Kansas from 2006 through 2009 to address this issue. Specific experiments included: evaluating optimum N rates from side-dressing nitrogen fertilizer; timing of nitrogen application, pre-plant vs. split applications and normal side-dress V-6-V-9 vs. late side-dress V-14-V-16; N response of corn to a late side-dress of nitrogen fertilizer; and the evaluation of optical sensors for making in season N recommendations. The specific objectives of this research were to: a. Determine the optimum N application rate and timing to optimize corn grain yields in different corn producing regions in Kansas. b. Confirm or revise the current K-State soil test based N recommendation system for corn. c. Evaluate N management strategies using the GreenSeeker, Crop Circle, and SPAD meter, crop sensors. d. Develop draft GreenSeeker, Crop Circle, and SPAD sensor algorithms for producers to use. Grain corn yields were responsive to N at all but 3 sites. Grain yields obtained at the sites ranged from 3,460 to 15,480 kg ha[superscript]-1. Optimum N rates varied from 0 to 246 kg N ha[superscript]-1. This work suggests that current K-State N fertilizer recommendations for corn need revisions due to over recommendation of N. Including different coefficients for irrigated and dry land corn along with N recovery terms would create a more accurate N recommendation system that more closely reflects the results obtained in these experiments, and provide a significant improvement over the current system. The optical sensors used in this study were effective at making N recommendations for corn. These sensors can be a valuable tool for producers to use and determine in season N status of corn.

Abstract:

The official U.S. standards for corn have been available for almost one hundred years. Corn grading system has been gradually updated over the years. In this thesis, we investigated a fast corn grading system, which includes the mechanical part and the computer recognition part. The mechanical system can deliver the corn kernels onto the display plate. For the computer recognition algorithms, we extracted common features from each corn kernel, and classified them to measure the grain quality.

Full text

Abstract:

Three cultivators, Rabewerk, Kongskilde and Hiniker, and three intercrops, soybean, lupin and red clover + rye grass were investigated for their impact on the incidence of ear rot of corn, a common disease of maize in eastern Canada. Wheat was seeded in the corn rows to serve as an additional indicator of cultivation and intercropping effects on the pathogen. An artificial inoculum of F. graminearum that produced perithecia and ascospores was used to mimic natural inoculum.
In 1993 and 1994, the infection in the corn was not very severe and there were no differences between the treatments and the controls.
In 1993 and 1994, at both sites, wheat seeds from cultivation trials showed a tendency for greater disease incidence in the non-cultivated herbicide treatment when compared to any of the other cultivator treatments. Cultivators till the soil and bury corn residues, this action led to the destruction of some of the inoculum and a subsequent reduction of the disease incidence in the cultivated plots.
In the intercrop trial of 1993 and 1994, wheat infection was moderate to severe, except at L'Assomption in 1993, but no significant differences were observed among the treatments. It is believed that interplot interference, due to ascospores moving from one plot to the next, masked differences.
The results indicated that weed cultivation would have a negligible or no effect on the development of fusarium ear rot of corn in Quebec. (Abstract shortened by UMI.)

Abstract:

Apple pomace is a solid by-product acquired from pressing and crushing millions of tons of apple in juice-industries. It represents 25-30 % of the original fruit and consists of peels, seeds and pulp. This raw material has multiple applications due to its high carbohydrate and moisture content. This bachelor thesis evaluated the use apple pomace acquired from Herrljunga cider for the cultivation of a filamentous fungus to produce biomass and ethanol. Different pretreatment strategies were applied to the apple pomace to extract as much sugars as possible. Several batches were made by mixing pomace and distilled water at different ratios (g pomace per g water) and different water temperatures. Apple juice was produced by filtering soaked pomace using a fine fabric. Apple pomace suspensions were made by adding pomace and water without mixing it (non-homogenised) and homogenised suspensions by mixing with a kitchen blender. Some apple juice batches were pH adjusted to 5.5 to investigate the effect on the fungal growth. The batches were put in Erlenmeyer flasks, sterilised and inoculated with the fungal strain Rhizomucor that has been isolated from Indonesian leaves used for tempe preparation. The Erlenmeyer flasks were incubated in a water shake for 72 h. Samples were taken every 24 h to follow sugar and ethanol concentrations. The samples were analysed by HPLC (High-Performance Liquid Chromatography). The results showed that apple pomace suspension did not perform well compared to the apple juice since the suspension was too viscous and lacked oxygen for the fungus to grow properly in the solution. The apple juice did show a significant improvement compared to the suspension, however pH adjustment to 5.5 had a negative impact on the fungal growth. Cold pre-treatment with an apple pomace to water ratio of 1 g pomace /g water produced the most biomass, with a yield of 9.7 g biomass per kg dry apple pomace. For ethanol production, an apple pomace to water ratio of 1 g pomace /g water using hot water had the highest yield of 11.2 g ethanol per kg dry apple pomace.
Äppelpressmassa är en solid biprodukt, producerad genom att pressa och trycka milliontals ton äpple i bland annat juiceindustrier. Den kvarstående massan motsvarar 25-30 % av äpplet och består utav skal, frön och fruktkött. Denna råvara har många tillämpningar då den har ett högt kolhydrat- och vätskeinnehåll. Detta examensarbete utvärderade användningen av äppelpressmassa från Herrljunga cider för att odla en filamentös svamp i syfte att producera biomassa och etanol. Massan blev utsatt för olika förbehandlingar för att extrahera så mycket socker som möjligt. Olika satser gjordes genom att blanda äppelpressmassa med vatten i olika förhållanden (g äppelpressmassa per g vatten) och olika vattentemperaturer. Äppeljuice producerades genom att filtrera blöt massa med ett fint tyg. Suspensioner gjordes genom att tillsätta vatten till massan och inte blanda det (icke-homogent). En annan variant gjordes genom att blanda äppelpressmassa och vatten med en mixer (homogent). Några utav äppeljuicesatserna pH justerades till 5.5 för att se hur det påverkade svamptillväxten. Satserna flyttades till Erlenmeyer flaskor, steriliserades och ympades med den filamentösa svampen Rhizomucor. Erlenmeyer flaskorna flyttades till ett skakvattenbad för att jäsa i 72 timmar. Prover togs var 24:e timma för att se socker- och etanolkoncentrationerna ändras. Detta analyserades med hjälp utav en HPLC. Resultaten visade att suspensionssatserna inte presterade bra jämfört med äppeljuicesatserna. Detta misstänks bero på att innehållet var väldigt visköst och hade lågt syreinnehåll för svampen att kunna växa. Att justera pH till 5.5 för äppeljuicesatserna visade sig inte vara bra, de presterade sämre jämfört med justerade satser. Förbehandlingen med en äppelpressmassa till vatten förhållandet på 1 g äppelpressmassa/1 g kallt vatten producerade mest biomassa med ett utbyte av 9.7 g torr biomassa per kg torr äppelpressmassa. För etanolproduktion hade förbehandlingsmetoden med en äppelpressmassa till vatten förhållandet på 1 g äppelpressmassa/1 g varmt vatten högst utbyte med 11.2 g etanol per kg torr äppelpressmassa.

This study traces the history of how farmers have used technologies from the eighteenth century to the present to form identities, not simply as ways of making greater economic profits. Using technologies becomes a way to 'perform' a person's sense of him or herself. This insight serves historians because it suggests that users, not just important inventors, drive technological change. My study also suggests that the relationship people have with technology (and how they use it to form their identities) has historical genealogies. Engineers and business people will also find my history useful because the notion of 'performative use' means that people's views of themselves can influence the way they adopt and employ technologies. Policy scholars will gain from my study because I show that the way people use technology to understand themselves has consequences in determining how they participate in controversies over science and technology policy. This narrative begins in the eighteenth century by analyzing how elites like Benjamin Rush viewed the agricultural practices of German farmers, regarded by many in the upper classes as backwards. I show how observances of German farmers by elites created a pattern repeated throughout American history where rural people would use technology to perform their identities for an outside observer. In addition, I describe an identity, which I call 'German agrarianism,' and contend that this rural self-image migrated to the Midwest when German farmers moved westward. German agrarianism had several important features including the association of morality with family-based production practices, an obsession with owning personal property, the inclusion of women in farming and land ownership, and the practice of performing identity through the use of material objects. Next, I describe a rural identity with English origins, one that other scholars have named 'Jeffersonian agrarianism.' This Jeffersonian identity saw farmers as heroes who conquered the frontier, preserved American democracy, and supported less moral urban dwellers. I argue that Jeffersonian agrarianism in the nineteenth century began to reject technological and social change and that this view of rural people as anti-modern has influenced the way observers of rural life have viewed farmers up to the present. This study then analyzes the rural-urban conflict of the 1920s, contending that farmers used technologies to develop their own rural modern identity, which I call 'rural capitalistic modernity.' Farmers used technology this way to combat a version of modernity, which I name 'urban industrialism.' This modern identity, arising from the cities, advocated improving rural life by making farms resemble urban factories. This factory model threatened German and Jeffersonian rural identities that existed prior to the 1920s because it removed the family as the center of production and advocated work processes that took control and property ownership away from farmers. In addition, urban industrialism saw farmers as backward and in need of reform, which offended farmers who saw themselves in heroic terms as a result of Jeffersonian agrarianism. I argue that many rural people in the 1920s used technology to perform an identity of rural capitalistic modernity as a means of combating these urban efforts to restructure farms as factories and stereotype farmers as 'yokels' or 'rubes.' This rural modern identity became reinforced during the Cold War because the farmer saw Soviet collectivized agriculture as posing the same threats as previous urban industrialism. In addition, the way farmers used technology to reinforce their views of themselves as modern became valuable to government actors in the United States who saw increased agricultural production as a weapon in defeating the Soviet Union. By the 1970s, farmers formed an identity called 'rural ultramodernity' in which they began to think of themselves as more modern than urban dwellers because of their design and use of advanced technologies and their role as producers in the global food network. This ultramodern identity incorporates aspects of previous rural identities, including an obsession with combating urban stereotypes of farmers as 'hicks.' In addition, this rural ultramodern identity views farmers as having an inborn modernity inherited from previous generations of farmers. I argue that this ultramodern way farmers think of themselves explains why rural people in the Midwest have embraced the erection of wind turbines, unlike residents of other regions in the U.S. From a policy perspective, this study also contends that debates over science and technology, such as efforts to render agriculture more sustainable and organic, are impacted by unexpressed fundamental views about nature and morality. Statements about these controversies often take the form of proxy arguments that sound 'rational' but mask these unstated ideas, and they often alienate those with opposing views. Current debates over genetically modified organisms, from a rural perspective, are actually unspoken clashes over rural ultramodern and organic identities hidden by 'objective' points made by both sides involving science or economics. This study also challenges the common notion that technology and production are male domains by showing how both men and women have used technology to construct their identities as producers on Midwest farms. This insight illustrates how disagreements over gender roles underlie current policy debates about agriculture. Farmers view organic discourse as threatening rural women's identities as modern producers by framing farming as an immoral, industrial, and male domination of a moral and female nature. Rural people view organic discourse as carrying on the tradition of urban industrialism, which saw farmers as backwards and farm women as unhappy and occupying an exclusively domestic sphere. This study suggests that any effort to reform agriculture must include farmers and incorporate the way rural people use technologies to form and reinforce their identities. At the same time, the conclusion advocates for a new rural identity that avoids farmer's tendencies to view all technologies as 'progress' regardless of their environmental or social impacts.

Abstract:

The western corn rootworm, or WCR, (Diabrotica virgifera virgifera LeConte) is the most significant pest of field corn (Zea mays) in the United States, and has recently expanded its range into Europe. Since 2004, hybrid corn containing Bt toxins targeting the corn rootworm complex have been heavily adopted and are now the primary control measure for this pest in North American corn production.

The evolution of resistance is an ongoing concern, and to ensure Bt products will retain their usefulness, insect resistance management (IRM) tactics using various refuge structures have been adopted. One of the key tenets of the refuge strategy is that males and females emerging from Bt and refuge plantings mate randomly. A violation of this largely untested assumption would lead to acceleration of resistance development.

To generate empirical field data on mating rates between beetles emerging from Bt and refuge plants, field cage studies using field populations of WCR in Indiana were utilized. Various refuge configurations were tested; all refuge plants were labeled using the stable isotope N15. This mark persists in the adult beetles after eclosion, allowing for collection and analysis of isotopic ratios of beetles in mating pairs. This approach was used to test the random mating assumption in Bt and refuge beetles collected from field cages. Other data collected include emergence rates, timing and sex ratios for each of the treatments.

Results indicate that mating based on natal host may not be as important of a factor as initially thought. Mixed mating occurs at a high rate when there are higher numbers of susceptible rootworms even though the measured fitness parameters between Cry3Bb1 and refuge adults were significantly different (p< 0.05). The main indication from this study is that not enough susceptible individuals are produced from a 5% refuge-in-a-bag strategy which is the dominant form of refuge planting in the United States.

The purpose of this thesis is to analyze whether the use of automated aeration systems for reducing moisture in corn during storage provides sufficient net present value for Nebraska corn farmers. The objective is to examine if an automated aeration system provides sufficient energy savings, marketing opportunities and reduced drying costs before corn delivery to an elevator. On-the-farm corn storage has steadily increased and harvesting corn before the moisture has achieved the desired targets cost farmers in drying charges and shrink. Farmers are interested in whether automated aeration systems can remove enough moisture from grain, without over-drying the bin, without spending a large amount of time determining when to run their grain bin aeration fans. Data for this project were obtained from four privately owned 60,000 bushel grain bins outfitted with the IntelliAir™ BinManager™ automated aeration system. Moisture samples were taken from each of the trucks hauling grain to the bin and again after removal of the corn after the automated system had ran for 9 months. Energy usage, drying charges, and shrink were calculated for the initial corn moisture averages and the moisture at the time of removal. Each bin was examined using Net Present Value (NPV) analysis to determine whether the energy savings were enough to offset the initial installation cost and annual expenses of the project. After the NPV was estimated for each of the bins, a sensitivity analysis of how corn price changes and no aeration required would affect the NPV analysis. Finally, an analysis of the total costs savings of a continuously ran aeration system was compared to the automated aeration system. The conclusion of the NPV analysis was that adding an automated aeration system would be profitable under most scenarios. More studies are needed to determine the profitability of automated aeration systems in different regions, moisture inputs, and bin sizes.

Abstract:

This dissertation expands upon the definition of eco-visualization artwork. EV was originally defined in 2006 by Tiffany Holmes as a way to display the real time consumption statistics of key environmental resources for the goal of promoting ecological literacy. I assert that the final forms of EV artworks are not necessarily dependent on technology, and can differ in terms of media used, in that they can be sculptural, video-based, or static two-dimensional forms that communicate interpreted environmental information. There are two main categories of EV: one that is predominantly screen-based and another that employs a variety of modes of representation to visualize environmental information. EVs are political acts, situated in a charged climate of rising awareness, operating within the context of environmentalism and sustainability. I discuss a variety of EV works within the frame of ecopsychology, including EcoArtTech’s Eclipse and Keith Deverell’s Building Run; Andrea Polli’s Cloud Car and Particle Falls; Nathalie Miebach’s series, The Sandy Rides; and Natalie Jeremijenko’s Mussel Choir. The range of EV works provided models for my creative project, Sculpting Corn Production, and a foundation from which I developed a creative methodology. Working to defeat my experience of solastalgia, Sculpting Corn Production is a series of discrete paper sculptures focusing on American industrial corn farming. This EV also functions as a way for me to understand our devastated monoculture landscapes and the politics, economics, and related areas of ecology of our food production.

Abstract:

This study investigated the use of sweet potatoes (Ipomoea batatas ) as a basic component to develop a medium for cultivation of lactic acid bacteria (LAB). Extract from baked sweet potatoes was used to form a sweet potato medium (SPM). SPM was supplemented with 4 g/L of each nitrogen source (beef extract, yeast extract, and proteose peptone #3). Lactobacilli MRS was used as a control medium. Ten LAB strains were used to determine the suitability of SPM serving the growth of LAB. Our results showed no significant (p < 0.05) differences in the optical density, maximum specific growth rates, and bacterial populations between MRS and SPM. SPM also maintained higher pH values throughout the incubation period compared to that in MRS. The cost of SPM was 47% less than the cost of MRS. Further step was taken to determine the suitability of SPM serving LAB enzymatic activity. LAB strains growing in SPM showed relatively higher β-glucosidases, acid phosphatase, and phytase activities and lower &agr;-glucosidase compared to that in MRS. Strains of L. reuteri showed the highest enzymatic activities of &agr;-glucosidase, acid phosphatase, and phytase whereas L. delbrueckii subsp. bulgaricus showed the highest β-glucosidases activity. Thus the enzymatic activity of L. reuteri growing in SPM was enhanced using six different metal ions. The response of L. reuteri strains to metal ions found to be strain dependent. The addition of Mg²⁺ and Mn²⁺ followed by the addition of Ca²⁺ showed the highest enhancement effect on all tested enzymes. These findings indicated that SPM is a suitable medium serving the growth and bioactivities of LAB and thus could be used as an alternative low cost medium.

Abstract:

A significant by-product of bioethanol plants is whole stillage, commonly used to produce animal feed due to its nutritious value, has a potential to be used to produce various value-added products while eliminating a costly process step is an alternative approach. In this study, production and separation of additional ethanol, fungal biomass and enzyme were successfully achieved with the cultivation in membrane bioreactors in batch process condition. Process optimization studies regarding fermentation and filtration conditions were carried out. Up to 10.4 g/l ethanol per litre of used whole stillage can be produced in simultaneous saccharification and fermentation (SSF) condition without any pH adjustment and additional pretreatment step. Also, 50% diluted whole stillage provided 87% higher ethanol production comparing to non-diluted medium. Moreover, 71 % higher biomass production was obtained with the filtrate of 50% diluted whole stillage comparing to 25% diluted one. Considering the achieved results, a two-stage cultivation using SHF (Separate Hydrolysis and Fermentation) strategy in membrane bioreactors for separation of ethanol, lignin-rich stream, protein-rich fungal biomass and enzymes was proposed. The present thesis showed that the integration of filamentous fungi with membrane bioreactors can increase the range of products that can be produced from whole stillage.

Abstract:

Filamentösa svampar används inom många biotekniska områden. Svamparnas biomassa kan användas till föda eller djurfoder, medan biprodukter som svampar producerar kan användas inom områden som industri samt medicin. Kultiveringen av Neurospora intermedia och Aspergillius oryzae genomförs på smör, raps och frityrolja i detta arbete för att få en större förståelse för hur svamparna kan växa på olika lipider samt skillnaden som kan uppstå mellan olika arter av filamentösa svampar. Under arbetes studeras biomassakoncentration, proteinhalt samt pH. Även problem som att svamparna kan lagra lipider i cellerna och att det kan påverka resultaten genom en ökning av biomassakoncentrationen diskuteras. Kultiveringarna genomfördes i Erlenmeyerflaskor med 20 g/L lipid samt saltblandning för att bestå med nödvändiga näringsämnen. För A.oryzae genomförs även kultivering i en airliftbioreaktor för att förstå hur svampen beter sig i större skala. Högst koncentrationen torrbiomassa som erhålls ifrån Erlenmeyerflaskorna är 18,49±1,90 g/L för A.oryzae samt17,31±1,14 g/L för N.intermedia med en proteinhalt för torr biomassa upp till ca 14%.Utbytetmellan torr biomassa och lipid som tillsatts i kultiveringen hamnade på 94,00%±0,06%(rapsolja) för A.oryzae samt 81,69%±0,007% (frityrolja) för N.intermedia. De höga utbytena kan förklaras med att svamparna kan lagra lipider i cellerna vilket även ger de höga koncentrationen av torr biomassa. För att förstå morfologin, lipidhalt i biomassan samt pH beteende behövs mer arbete utföras med ändring av parametrar som pH justeringar, temperatur, luftflöde samt analys av biomassan för att utreda hur mycket lipider som lagras.
Filamentous fungi are used in many different biotechnological fields. The fungal biomass can be used for food or feed, while by-products that the fungi produce can be used in different industries or medical applications. The cultivations of Neurospora intermedia and Aspergillius oryzae implemented on butter, rapeseed and frying oil that is used in this work is for the larger understanding of how the fungi can grow on different lipids and the difference between species of fungi. Biomass concentration, protein content and pH are the main focus during this work, but problems like lipids storage in the biomass that can affect the results by increase of the total biomass concentration is discussed. The cultivations were implemented in Erlenmeyerflasks with 20 g/L lipid with added saltsolution with necessary nutrients. For A.oryzae cultivation in an airlift bioreactor was carried out for the understanding of larger scale cultivation. Highest concentration of dry biomass obtained from Erlenmeyerflasks are 18,49±1,90 g/L for A.oryzae and 17,31±1,14 g/L for N.intermedia with protein content for dry biomass up to 14%.The yield for dry biomass perlipid added during the cultivation ended at 94,00%±0,06% (rapeseed oil) for A.oryzae and 381,69%±0,007% (frying oil) for N.intermedia. During cultivation the cells can store lipids and that explains the high yields and biomass concentrations. For the understanding of morphology, the amount of lipids in the biomass and pH behaviour needs more work that includes changes of parameters like pH adjustment, temperature, airflow and analysis of the biomass for lipid content.

Abstract:

The use of genetically modified (GM) maize technology is subject to compliance with stewardship requirements and the adoption of specific management practices that promote the long-term effectiveness and environmental sustainability of the technology. For smallholders to comply with these requirements and adopt the desired management practices to ultimately benefit from the technology, they require information that creates awareness of the value of these requirements. To determine what information farmers receive about GM maize and how this information is disseminated to farmers, face to face interviews were conducted with 81 extension personnel and 210 smallhoder GM maize farmers in the Eastern Cape Province of South Africa. The effect of Bt maize introduction and management practices in smallholder maize agroecosystems in the Eastern Cape on Bt maize target [Busseola fusca (Fuller) (Lepidoptera: Noctuidae)] and non-target insect pests [Agrotis segetum (Denis & Schiffermüller) (Lepidoptera: Noctuidae), Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)] and a snail species, [Cornu aspersum (Müller) (Gastropoda: Helicidae)] was determined through laboratory, field and cage experiments. The effect of smallhoder farmers‟ GM maize cultivation practices on the profitability of GM maize technology was also determined through on-farm trials in different localities of the Eastern Cape identified as hot-spots for stem borer and weed infestation. Results of surveys indicated that extension personnel had a low level of awareness of GM maize technology stewardship requirements. GM maize technology was also largely disseminated to smallholder farmers through non-participatory approaches and print media sourced from GM seed companies. Although farmers had a high level of contact with extension services, they lacked access to information about GM maize technology. Smallholder farmers‟ level of awareness about GM maize and compliance with the requirement for the planting of non-Bt maize refuge areas adjacent to Bt maize was also very low. While Bt maize event (MON810) commonly cultivated by smallholder farmers in the Eastern Cape Province had a variable effect on A. segetum under laboratory conditions, it had no effect on the incidence of plants damaged by A. segetum and C. aspersum under field conditions. The incidence of H. armigera damage on Bt maize plants was however significantly affected by Bt maize. Populations of B. fusca collected from smallholder maize fields in the province were observed to be still highly susceptible to Bt maize. Results of on-farm evaluation of the profitability of GM maize revealed that stem borer pressure, growing conditions, input supplies and market access affect the productivity and profitability of GM maize cultivation. Challenges within the extension and advisory services of the Eastern Cape which can militate against smallholder farmers‟ ability to benefit from GM maize technology and sustain the long-term efficacy of the technology were identified during this study. Given these challenges and the fact that the cultivation of GM maize may not be profitable under typical smallholder maize cultivation conditions and management practices, dissemination approaches that provide farmers the opportunity to evaluate GM maize technology alongside alternate technologies under their conditions, may prove beneficial.

Abstract:

Enzymes and subcritical water can be used for the extraction of hemicelluloses from cereal by-products, making the processes eco-friendly. The polysaccharides extracted from cereal by-products can be used as matrices for development of materials for various applications. This includes bio-based materials such as films and hydrogels, which offer alternatives to existing materials produced from petrochemicals. The polymeric structure of cereal hemicelluloses contains functional groups which enable the modification of their structure by cross-linking, resulting in the formation of hydrogels. This project aims to use subcritical water extraction (SWE) to extract arabinoxylans (AXs) from corn and rye bran meanwhile the enzymatic treatment is done for purifying the samples during both pre- and post-treatment. AXs were further crosslinked by enzyme (laccase) for hydrogel preparation. During the whole project, the characterization included moisture and yield determination, starch and protein content which were tested using a spectrophotometer, monosaccharide content was analyzed by high performance anion exchange chromatography followed by pulsed amperometric detection (HPAEC-PAD) and phenolic acid content was quantified by high performance liquid chromatography (HPLC). The pretreatment for destarching and SWE process was successful. The result showed that arabinoxylans form corn bran were having higher content of arabino substituents, arabino toxylans ratio and ferulic acid content than rye samples. The enzymatic crosslinking could form strong gels in the condition that the AXs had high ferulic acid content. In terms of forming strong hydrogels or to improving the properties of AXs gel, the pre- and post-treatment should be optimized to increase the purity of the extracted feruloylated AX content.
Enzymer och subkritiskt vatten kan användas för extraktion av hemicellulosa från spannmålsbiprodukter, vilket gör extraktionen miljövänlig. Polysackariderna extraherade från spannmålsprodukter kan användas som matriser för utveckling av material för diverse applikationer. Detta inkluderar biobaserade material som filmer och hydrogeler, där petrokemikalier kan ersättas som råvara. Den polymera strukturen hos spannmålshemicelluloser innehåller funktionella grupper som möjliggör formation av tvärbindningar vilket resulterar i bildandet av hydrogeler. Syftet med detta projekt är extraktion av arbinoxylaner (AXs) från majs och rågkli genom att använda subkritiskt vatten-extraktion (SWE) där rening under för- och efterbehandling utförs enzymatiskt. AX modifierades därefter enzymatiskt (laccas) med tvärbindningar för hydrogelframställning. Under hela projektet karakteriserades hydrogelen utifrån fuktinnehåll, bestämmelse av utbyte, stärkelse och proteininnehåll som testades med en spektrofotometer, monosackaridhalten analyserades med högpresterande anjonsutbyteskromatografi följt avpuls-amperometrisk detektion (HPAEC-PAD), samt kvantifierades fenolsyrahalten med högupplöst vätskekromatografi (HPLC). Resultatet visade att arabinoxylaner från majskli hade högre innehåll av arabinosubstituenter, där förhållandet mellan arabino och xylans, samt arabino och ferulsyra innehållet var högre än för rågproverna. Den enzymatiska tvärbindningen kunde bilda starka geler i det tillståndet där AX hade en hög ferulsyrahalt. När det gäller att bilda starka hydrogeler eller att förbättra egenskaperna hos AXs-gel, bör för-och efterbehandlingen optimeras för att öka renheten fördet extraherade feruloylerade AX-innehållet.

Abstract:

The changes occurred in the agriculture with the introduction of technology lead the natural resources to become more fragile when we consider the way of production developed under the conventional system, in which it keeps using machines, tractors, chemical defenses and external inputs. Through the last five years the corn agroecosystems in the State of Sergipe developed a modern agriculture, where besides being cultivated as a subsistence agriculture it has become an agribusiness, a source of income mainly in Carira and Simão Dias, the most important corn producers cities of the State. Facing the changes of the technological standards on the corn production in Sergipe, a research was made focusing on the technological level in the corn agroecosystems in the state of Sergipe. The main point was based on the analysis of the technological levels in the exploration of the corn agroecosystems in the State of Sergipe facing the changes caused by the insertion of technologies in the agriculture. A field research was made, and 15 indicators were selected and the potential and boundary points were observed. Questionnaires were applied for the data capture, besides a test of the mechanical resistance to the penetration to analyze the soil compaction. The research considered the systemic approach focusing on the environment, social and economical dimensions in the corn production in the middle- west region of Sergipe. The monoculture practice was highlighted; the excessive use of chemical defensives as well the adoption of more than 90% of the transgenic seeds among the producers. The weather become the biggest challenge for the producers in the period that the research was made for they faced an atypical condition occurred in the 2010 crop that lead not only a reduction of the production but also all the crop lost in some properties. For the soil factor, it should have used more conservative practices focusing on keeping a way of production more sustainable, in those practices the highlighted are the direct planting and the crop rotation. Generally, it should rethink the corn culture expansion mainly in Carira and Simão Dias in a way that would search to develop practices that lead in consideration not only the economical factor but also the environmental and the social ones.
As mudanças ocorridas na agricultura com a introdução da tecnologia têm levado os recursos naturais a tornarem-se mais frágeis diante do modo de produção desenvolvido sob o sistema convencional, no qual mantem-se com uso de máquinas, tratores, defensivos químicos e insumos externos. Nos agroecossistemas do milho no Estado de Sergipe desenvolveram-se nos últimos cinco anos uma modernização na agricultura, onde o milho além de ser cultivado como uma cultura de subsistência torna-se um agronegócio, fonte de renda principalmente dos municípios de Carira e Simão Dias maiores produtores de milho do Estado. Diante das mudanças nos padrões tecnológicos na produção do milho em Sergipe, realizou-se a pesquisa que abordou os Níveis Tecnológicos nos Agroecossistemas do Milho no Estado de Sergipe. O objetivo geral pautou-se na análise dos níveis tecnológicos na exploração dos agroecossistemas do milho no Estado de Sergipe diante das transformações ocasionadas pela inserção das tecnologias na agricultura. Foi realizada uma pesquisa de campo, e selecionou-se 15 indicadores onde foram observados os pontos potenciais e limitantes. Aplicaram-se questionários para coleta de dados, além de um teste de Resistência Mecânica à Penetração para analisar a compactação do solo. A pesquisa contemplou o método sistêmica abordando as dimensões ambiental, social e econômica na produção do milho na região centro-oeste de Sergipe. Destacou-se a prática da monocultura na região, o uso excessivo de defensivos químicos bem como a adoção de mais de 90% das sementes transgênicas entre os produtores. No período que se realizou a pesquisa o clima tornou-se o maior desafio para os produtores da região diante de uma condição atípica ocorrida na safra de 2010 levando além da redução da produtividade, também a perda de toda a safra em algumas propriedades. Quanto ao fator solo devem-se adotar práticas mais conservacionistas visando manter uma produção mais sustentáveis, dessas práticas destacam-se o plantio direto e a rotação de cultura. De modo geral deve-se repensar a expansão na cultura do milho principalmente nos municípios de Carira e Simão Dias de modo a buscar desenvolver práticas que levem em consideração não só o fator econômico, mas também o ambiental e o social.

Abstract:

This is a case study dissertation to research the socio-political conflict surrounding Gilles Eric Séralini’s et al (2012) research on the toxicity of Monsanto’s NK603 line of corn and the herbicide Roundup. The study analyzes this conflict as a system of interconnected and often conflicting interests, assumptions and ideologies about how knowledge is created and transformed from the research stage to the policy implementation stage. The goal of this study is to: 1.) analyze critical surface level and underlying factors that contribute to the conflict; 2.) analyze systemic processes between national and international researchers, private interests and government policymakers in developing and implementing research protocols, policies and regulations pertaining (but not limited) to Monsanto’s NK603 corn and Roundup; 3.) identify potential patterns of knowledge transformation from the research stage to policy implementation. The theoretical approach used in this study considers social construction, critical theory and Kuhn’s theory of scientific revolution. In utilizing case study methodology, this study incorporates internal analysis of Séralini’s case with a basic comparative analysis of DDT and lead policy processes and knowledge transformation, using mainly secondary data sources supplemented with primary interview material from two select researchers using purposive sampling. By conducting this research, it is hoped that this study reveals a better understanding of the complex interconnected systems that help create and transform food safety policies and the science that supports and/or transforms them.

Abstract:

In today’s society there is a growing awareness of where food is produced and there is a trend to use locally grown produce in restaurants. One way for restaurants to differentiate themselves is to grow the produce inside the restaurant. This thesis has the aim on identifying the problems and user needs for an indoor cultivation solution and developing a new indoor cultivation product that solves the identified problems and meet the user needs. To achieve this aim, a usercentered design approach was utilised and the following three research questions were answered: How can the needs of the user be translated into a product specification for indoor cultivation in restaurants? What are the functionality, usability, and construction requirements for an indoor cultivation product in a restaurant? What product concept can be designed to grow classic herbs in restaurants based on the needs of the user? To identify the needs interviews were performed with the users. The needs were then translated, together with the company’s needs, into a product specification. This was done in two steps, identifying the metrics and setting values. Some of the most important requirements are that a hydroponic system is used, that the product is easy to clean and is moveable. The product development process was iterative and included different ideation, development and evaluation methods. The users were involved in some of the evaluation methods to give input on the final design. Their opinion, together with evaluations based on the product specification, were used when choosing the final concept Lärad. Lärad uses a circulating hydroponic system and have three separate growing containers each containing 16 plants. The growing containers can be pulled out to enable easy access of the plants. Both the water system and the LED grow lights, that replaces natural sunlight, are controlled automatically to minimise the users’ involvement. To test the concept, to see how well the product specification is fulfilled, both a CAD model and a functional prototype were created. The results from the tests were, even at the concept stage, that 97% of all the tested requirements were fulfilled which shows that the concept is suitable for indoor cultivation in a restaurant environment. Some further work that includes refining the design and optimising for production will be needed to launch the product.

Abstract:

This bachelor thesis examines to what extent a co-create community called Bobyggetin Herrljunga, Sweden, can be food self-sufficient. To obtain a more comprehensiveresult, the difference between a vegetarian and non-vegetarian diet, as well as howtime spent on farming and available cultivation area affects the outcome, are studied.Moreover, difficulties regarding food self-sufficiency are brought up and discussed.Linear programming is used to maximise the amount of calories obtained fromfarming at Bobygget. The result shows that the degree of self-sufficiency at Bobyggetreaches 21% with vegetarian food, and 27% with non-vegetarian food. With thepreconditions regarding the available area of Bobygget, the maximum work time peradult is 9 min per day for vegetarian food, and 13 min per day for non-vegetarianfood. Difficulties concerning self-sufficiency, including time consumption and basicfarming knowledge, are identified. Possible solutions, such as starting modestly withfew crops and small area, consider contract farming, and create a knowledge base forBobygget, are presented.

Abstract:

The aim of this work was to investigate and determine central parameters that can be used to control and increase the solubility, quality and productivity of recombinant proteins. These central parameters should be applicable under the constraints of high-throughput protein production in Escherichia coli.

The present investigation shows that alternative methods exist to improve solubility, quality and productivity of the recombinant protein. The hypothesis is that by reducing the synthesis rate of the recombinant protein, a higher quality protein should be produced. The feed rate of glucose can be used to decrease the synthesis rate of the recombinant protein.

The influence of feed rate on solubility and proteolysis was investigated using the lacUV5-promoter and two model proteins, Zb-MalE and Zb-MalE31. Zb-MalE31 is a mutated form of Zb-MalE that contains two different amino acids. These altered amino acids greatly affect the solubility of the protein. The soluble fraction is generally twice as high using Zb-MalE compared to Zb-MalE31. Using a low feed rate compared to high benefits the formation of the full-length soluble protein. Furthermore, by using a low feed rate, the proteolysis can be decreased. One other factor that influences the solubility is the amount of inducer used. An increase from 100 µM to 300 µM IPTG only results in more inclusion bodies being formed, the fraction of soluble protein is the same.

The quality aspect of protein production was investigated for a secreted version of Zb-MalE using two different feed rates of glucose and the maltose induced promoter PmalK. It was shown that when the protein was secreted to the periplasm, the stringent response as well as the accumulation of acetic acid (even for high feed rates) was reduced. The stringent response and accumulation of acetic acid are factors that are known to affect the quality and quantity of recombinant proteins. Transporting the protein to the periplasm results in this case on a lower burden on the cell, which leads to less degradation products being formed when the protein is secreted to the periplasm.

Seeing the feed rate as a critical parameter, the high-throughput production would benefit from a variation in the feed rate. However, since the fed-batch technique is technically complicated for small volumes another approach is needed. E.coli strains that have been mutated to create an internal growth limitation that simulate fed-batch were cultivated in batch and were compared to the parent strain. It was shown that the growth rate and acetic acid formation was comparable to the parent strain in fed-batch. Furthermore it was shown that a higher cell mass was reached using one of the mutants when the cells were cultivated for as long time as possible. The higher cell mass can be used to reach a higher total productivity.

The formation of a garlic high yield is achieved by a scientifically sound set of agronomic techniques. One of the effective way to improve the technology of cultivation is the improvement of mineral nutrition of garlic plants during the growing season. The program of garlic fertigation with the use of completely water-soluble complex fertilizers is investigated. Optimal doses and terms of fertilizer application are proposed, which take into account the natural and climatic conditions of cultivation and physiological needs of garlic plants. The results of the experiment showed that the use of the fertigation system helps to improve the content of nutrients in garlic bulbs and increase their weight, which affects the yield increase.

Abstract:

A utilização de novas tecnologias e a adoção de inovações na agricultura são fundamentais para o estabelecimento dos padrões de produção, pois, além de mitigarem riscos específicos associados a este ramo de atividade, impactam nos resultados agronômicos, econômicos e financeiros do negócio rural. Diversos aspectos derivam dessa discussão e suscitam questões como: Quais são os condicionantes de adoção de Agricultura de Precisão (AP) por produtores de grãos? Qual é o grau de adoção e uso de Agricultura de Precisão? Quais são as características do produtor rural e da fazenda, as principais tecnologias utilizadas e os fatores de maior influência na adoção de Agricultura de Precisão? Qual é a influência das características do produtor, características da fazenda e fontes de informação na adoção de Agricultura de Precisão? Partindo dessas questões de pesquisa, o objetivo geral do trabalho foi identificar os condicionantes de adoção de Agricultura de Precisão por produtores de grãos. Os objetivos específicos foram: mensurar o grau de adoção e uso de AP; caracterizar o produtor rural e a fazenda, as principais tecnologias utilizadas e os fatores de maior influência na adoção de AP; analisar a influência das características do produtor, características da fazenda e fontes de informação na adoção de Agricultura de Precisão. Essa pesquisa é caracterizada como estudo exploratório e descritivo, com aplicação de técnicas de análise quantitativas. Foram realizadas 404 entrevistas presenciais com produtores de soja e milho. A análise dos dados foi feita com a técnica de regressão logística. Constata-se que os condicionantes encontrados são relacionados a características do produtor, como educação e importância da renda da agricultura, a características da fazenda, como área de safrinha de milho, a fontes de informação, como assistência técnica e extensão rural - Emater/Cati, e aos meios de comunicação, como palestras e publicações de universidades. As tecnologias no estágio de Maioria Inicial (Até 50% da população) são análise de solos, aplicação de corretivos e fertilizantes em taxa variável, amostragem de solo em grade (Georreferenciada), mapa de aplicação, piloto automático, aplicação de defensivos em taxa variável, GPS com barra de luz, monitor de colheita e mapa de produtividade. As tecnologias adotadas pelos Pioneiros (Até 16% da população) são semeadura em taxa variável, GPS com correção RTK, sensoriamento remoto (aéreo/satélite/outros) e irrigação de precisão. A única tecnologia somente adotada pelos Inovadores (até 2,5%) foram os sensores de plantas daninhas, pragas e doenças. Por fim, o trabalho sugere temas para estudos futuros.
The use of new technologies and the adoption of innovations in agriculture are critical for the establishment of production standards, because they mitigate specific risks associated with this field of activity, impact on the agronomic, economic and financial results of the rural business. Several aspects derive from this discussion: What are the determinants of adoption of precision agriculture (PA) of grain producers? What is the level of adoption and use of Precision Agriculture? What are the characteristics of the farmer and the farm, the main technologies used and the most influential factors in the adoption of Precision Agriculture? What are the influence of producer characteristics, farm characteristics and sources of information on the adoption of Precision Agriculture? Based on these research questions, the main objective of this study was to identify the determinants of adoption of Precision Agriculture of grain producers. The specific objectives were to measure the level of adoption and use of PA; characterize the farmer and the farm, the main technologies used and the most influential factors in the adoption of PA; analyze the influence of producer characteristics, farm characteristics and sources of information on the adoption of Precision Agriculture. This research is characterized as exploratory and descriptive study, with application of quantitative analysis techniques. 404 face to face interviews were conducted with producers of soybeans and corn. Data analysis was performed with logistic regression. The PA adoption determinants found are related to producer characteristics such as education and importance of agricultural income, the farm characteristics such as second crop corn area (safrinha), sources of information, technical assistance and rural extension - Emater / Cati and the media, such as lectures and university publications. Technologies in Initial Majority stage are soil analysis, application of fertilizers in variable rate, soil sampling grid (Georeferenced), application map, autopilot, application of pesticides in variable rate, GPS with light bar, harvest monitor and productivity map. The technologies adopted by Pioneers are variable rate seeding, GPS with RTK correction, remote sensing and precision irrigation.

Abstract:

Une enquête agronomique pluriannuelle a été conduite sur culture de maïs dans de petites exploitations de l'ouest du Burkina Faso. La pluviométrie, le rayonnement et la température de l'air journaliers, la composition du sol, la taille et les moyens de l'exploitation, les événements culturaux et les composantes du rendement ont été relevés. Les données révèlent une extrême diversité de situations pour les pratiques culturales rencontrées et les rendements obtenus. Cependant, des types de stratégies déterminées par les agriculteurs suivant leurs objectifs d'autoconsommation ou de commercialisation sont dégagés. Le diagnostic des contraintes locales affectant le rendement est fondé sur son analyse en quatre composantes : le nombre de pieds, la fréquence de plantes fertiles, le nombre de grains par plante fertile, et le poids d'un grain. Leur valeur est comparée à des valeurs potentielles. Des indices de réalisation des différentes phases du cycle sont ainsi définis pour quantifier les contraintes locales et les situer dans le temps. Un traitement qui distingue les situations de contraintes durables (de type fertilité) de celles de contraintes passagères ou accidentelles est proposé. Ce sont les contraintes durables qui sont les plus fréquentes dans les conditions étudiées. De même, que les contraintes accidentelles, elles dépendent davantage des techniques culturales et de la fertilité que des facteurs environnementaux. Cette méthode permet de conduire une analyse satisfaisante des différents types de situations rencontrées. Toutefois, le diagnostic est limité par la quantité de données caractérisant les facteurs abiotiques sources de contraintes.

Abstract:

Humanpatogena stammar av bakterien Yersinia enterocolitica kan orsaka akut gastroenterit. För identifiering av bakterien odlas fecesprover ut på CIN-agar. På senare år har en kromogen agarplatta framtagits som differentierar mellan patogena och apatogena stammar av Y. enterocolitica. Syftet med studien är att jämföra och utvärdera två CIN-agar, med agarbaser och supplement från två olika företag (Liofilchem och Oxoid), och CHROMagar Y. enterocolitica (CHROMagar). Odling av fecesprover samt seriespädning av sex Y. enterocolitica stammar och en Y. pseudotuberculosis utfördes. Vid utodlade fecesprover jämfördes växt och hämning av övriga bakterier. Vid seriespädning räknades antal kolonier på plattorna för respektive spädning, samt utseende av kolonier på plattor bedömdes. Resultatet tyder på att skillnad av hämningseffekt av Y. enterocolitica och utseende på kolonierna finns mellan de två CIN-agarplattorna. Oxoid’s CIN-agar erhöll större kolonier, lägre hämningseffekt av Y. enterocolitica och detektionsgräns än Liofilchem’s CIN-agar. På CHROMagar-plattan växte de patogena stammarna med bleklila kolonier och de apatogena stammarna med blåa kolonier. Hämningseffekt av Y. enterocolitica hos CHROMagar-plattan är densamma som Oxoid’s CIN-agar. Slutsatsen är således att Oxoid’s CIN-agar och CHROMagar har samma hämningseffekt av Y. enterocolitica men CHROMagar differentierar mellan patogena och apatogena stammar. Liofilchem’s CIN-agar har högre hämningseffekt än CHROMagar och Oxoid’s CIN-agar.
Pathogenic strains of Yersinia enterocolitica can cause acute gastroenteritis in humans. To identify the bacterium, cultivation of stool samples on CIN-agar are performed. A chromogenic medium has been developed that differentiate between pathogenic and nonpathogenic strains of Y. enterocolitica. The purpose is to compare and evaluate two CIN-agar, with agar bases and supplements from two companies (Liofilchem and Oxoid), and CHROMagar Y. enterocolitica (CHROMagar). Growth of stool samples and serial dilutions of six Y. enterocolitica strains and one strain of Y. pseudotuberculosis were performed. Comparisons of the growth and inhibition of other bacteria were done for the stool samples. Colonies for each dilution were counted and appearance of the colonies was evaluated. The result indicates that a difference in inhibitory effect on Y. enterocolitica and appearance of colonies exist between the two CIN-agar. All strains grew with larger colonies on Oxoid CIN-agar than on Liofilchem’s. Oxoid CIN-agar and CHROMagar have a lower inhibitory effect on Y. enterocolitica than Liofilchem’s. On CHROMagar, the pathogenic strains grew with mauve colonies, whilst the nonpathogenic strains grew with blue colonies. Thus, the conclusion is that CHROMagar and Oxoid CIN-agar have less inhibitory effect on Y. enterocolitica than Liofilchem’s. CHROMagar can differentiate between pathogenic and nonpathogenic strains.

The physical and microbiological soil properties have been widely used in monitoring its quality. This is of great importance in determining the impactful as soil management can be., which are very important for determining how impactful a soil management may be, have been widely used for monitoring soil quality. Thus, the objective of this study was to evaluate the physical and microbiological soil characteristics under cultivation and crop successions systems for ten years, in an Ultisol. The no-tillage (PD) and conventional tillage (PC), and succession crops of corn-beans (M-F) and soybean- wheat (S-T) were evaluated. For this, a field experiment in a split plot design was used, where the plots were the no-tillage (PD) and tillage (PC) systems and the subplots were the crop successions, corn-bean (M-F) and soybeans -wheat (S-T), in a completely randomized design with four replications, to physical characteristics of the soil, and three replicates for soil microbiological characteristics. Bulk density (Ds), macroporosity (Mac), microporosity (Mic), total porosity (Pt), organic matter content (MO) in the depths of 0-5; 10-15 and 20-25 cm; soil penetration resistance (RP) to a depth of 60 cm, microbial biomass carbon (MBC), soil respiration rate (C-CO2), metabolic quotient (qCO2) , microbial quotient (qMIC) and the content of total organic carbon (COT) in the depths of 0-5; 5-10 and 10-15 cm were all evaluated. Higher microporosity and total porosity of the soil was found at 0-5 cm depth in no-tillage system when C-B succession was cultivated. Bulk density was lower in both 10-15 cm and 20-25 cm depths when using the conventional tillage. Higher values of organic matter in the surface were found in the corn-bean succession in the no-tillage system. There was greater variation in the soil penetration resistance in the 5-25 cm depth, with higher RP at S-T succession in no-tillage system and reduced RP in the M-F succession in conventional tillage. Soil respiration rate differ between crop succession only in the 0-5 cm depth, which was greater for C-B succession. Conventional tillage presented higher amount of total organic carbon than no-tillage system at depths of 5-10 and 10- 15 cm. The qCO2 differed between crop successions at the depth of 10-15 cm, where the soil with the M-F succession presented the highest value. The physical and microbiological soil characteristics were affected by the tillage systems and crop ix successions after ten years. The no-tillage system yielded improvements in some physical soil properties in comparison to conventional tillage in the first 5 cm of soil after ten years of use. The cultivation M-F succession resulted in higher porosity in the soil surface and in the subsurface. The crop successions affected soil respiration rate only in the lower depth. An increased activity of microorganisms in soil is found when using the bean-corn succession crop.
As características físicas e biológicas do solo vêm sendo muito utilizadas no monitoramento da sua qualidade, sendo de grande importância na determinação do quão impactante determinado manejo de solo pode ser. Assim, objetivou avaliar as características físicas e microbiológicas do solo sob sistemas de plantio e sucessões de culturas por dez anos, em um Argissolo Vermelho-Amarelo. Foram avaliados os sistemas plantio direto (PD) e plantio convencional (PC) e as sucessões de culturas milho-feijão (M-F) e soja-trigo (S-T). Para isso, utilizou-se um experimento de campo em esquema de parcelas subdivididas, tendo nas parcelas os sistemas de plantio direto (PD) e convencional (PC) e, nas subparcelas, as sucessões de culturas, milho-feijão (M- F) e soja-trigo (S-T), no delineamento inteiramente casualizado com quatro repetições, para caracteristicas física do solo, e três repetições, para caracteristicas microbiologicas do solo. Avaliaram-se a densidade do solo (Ds), macroporosidade (Mac), microporosidade (Mic), porosidade total (Pt), teor de matéria orgânica nas profundidades de 0-5, 10-15 e 20-25 cm, resistência mecânica do solo à penetração (RP) até a profundidade de 60 cm, carbono da biomassa microbiana (CBM), taxa respiratória dos microrganismos no solo (C-CO2), quociente metabólico (qCO2), quociente microbiano (qMIC) e teor de carbono orgânico total (COT) nas profundidades de 0-5, 5- 10 e 10-15 cm. O solo sob plantio direto, na profundidade de 0-5 cm, apresentou maior microporosidade e porosidade total do solo quando cultivada a sucessão M-F. A densidade do solo foi menor quando utilizado o plantio convencional, tanto na profundidade de 10-15 cm, quanto na de 20-25 cm. Maiores teores de matéria orgânica em superfície foram observados no plantio direto da sucessão M-F. Houve maior variação na RP entre 5 e 25 cm de profundidade, com maiores valores no plantio direto sucessão S-T e menor RP no plantio convencional sucessão M-F. A taxa respiratória dos microrganismos do solo diferiu entre as sucessões de culturas apenas na profundidade de 0-5 cm, sendo ela maior para a sucessão M-F. O solo sob plantio convencional apresentou, nas profundidades de 5-10 e 10-15 cm, maior teor de carbono vii orgânico total que o do plantio direto. O qCO2 foi maior para o solo com a sucessão M- F diferiu entre as sucessões de culturas na profundidade de 10-15 cm, tendo o solo com a sucessão M-F maior valor. As características físicas e microbiológicas do solo foram afetadas pelos sistemas de plantio e sucessões de culturas, após dez anos. O plantio direto proporcionou melhorias em algumas características físicas do solo, em relação ao plantio convencional, nos primeiros 5 cm de solo, depois de dez anos de uso. O cultivo da sucessão M-F resultou em maior porosidade no solo em superfície e em subsuperfície. As sucessões de culturas influenciaram a taxa respiratória dos microrganismos no solo apenas na menor profundidade. Maior atividade dos microrganismos no solo é observada quando empregada a sucessão milho-feijão.

Кухаренко ; керівник роботи Л. А. Шевченко ; НУ "Чернігівська політехніка", кафедра аграрних технологій та лісового господарства. – Чернігів, 2021. – 43 с.
У першому розділі обґрунтована тема за літературними джерелами. Наведена детальна інформація по соняшнику, стан та перспективи його вирощування в Україні та світі ,описані біологічні та сортові особливості культури. У другому розділі наведена характеристика господарства «Яна Плюс». Подані загальні відомості про господарство, охарактеризовано ґрунтовокліматичні умови та представлена технологія вирощування культур. Недоліки в технології вирощування соняшнику та рекомендовані заходи її поліпшення наведені у розділі 3. У 4 розділі проведена економічна оцінка запропонованих заходів технології вирощування соняшнику. Отже, за результатами досліджень приріст чистого доходу соняшнику виріс на 18,1%. А під час заміни закордонних ЗЗР вітчизняними виявлено, що система захисту в господарстві коштує 2828грн/га, а запропонована – 1128 грн/га.
