Resumen

Abstract Quality Protein Maize (Zea mays L.) (QPM) varieties have been developed by scientists at the Institute of Agricultural Research and Training in Nigeria. For these varieties to have significant impact, they must possess traits acceptable to farmers. A study was carried out to evaluate the agronomic and sensory traits of two Quality Protein Maize - ART-98-SW-6-OB (QPM1) and ILE-1-OB (QPM2), in comparison with ART-96-SW-1 (High Protein Maize) and SUWAN-1-SR (a popularly grown improved variety) in three maize growing communities of South West, Nigeria. Sixty (60) farmers comprising males and females were evaluated for six sensory parameters. The parameters tested were appearance, colour, flavour, texture, taste and overall acceptability. The results of the agronomic evaluation showed that there were no significant differences in the height of QPM varieties and HPM at harvest. QPM varieties gave the highest grain yield of 2.38t/ha for ART-98-SW-6OB and 2.36t/ha for ILE-1-OB. Sensory evaluation showed that when the maize varieties were processed into corn-soy milk, QPM corn-soy milk had the highest sensory scores for all sensory parameters tested. Quality Protein Maize varieties had high grain yield and were most preferred for maize pudding and corn - soy milk. The QPM varieties, if formulated into foods for household or commercial purposes, should have good chance of being accepted by farmers with continuous promotional campaigns.

Resumen

In Rational Choice and British Politics, Iain McLean applies William Riker's concept of “heresthetics” to British political history. In contrast to rhetoric (the art of persuasion), heresthetics is “the art and science of political manipulation” (p. 10). Rather than trying to convince others of one's position, heresthetics is about transforming the question and altering political dimensions so as to change the rational calculus of key actors and manufacture a supportive coalition. McLean employs the device of “analytical narratives” (historical analysis informed by rational choice methodology) to explore critical junctures in British political development, including the repeal of the Corn Laws, the Second Reform Act, the signing of the Anglo-Irish Treaty in 1922, and the political and economic revolution of Margaret Thatcher. He also explores broader political movements, including the realignment of Victorian political parties and the attempts by Joseph Chamberlain and Enoch Powell to connect race and empire into winning coalitions.

Resumen

WeedSOFT is a state-of-the-art decision support system for weed management in the north central region of the United States, but its accuracy to predict corn yield loss associated with later-emerging weed communities has not been adequately assessed. We conducted experiments in 2004 and 2005 to compare observed and predicted corn yield related to four establishment times of mixed-species weed communities for validation of competitive index modifier (CIM) values in WeedSOFT. Weed communities were established at VE, V2, V4, and V6 corn (emergence, second-leaf, fourth-leaf, and sixth-leaf stages, respectively), and consisted largely of annual grass and moderately competitive annual broadleaf species. Compared to weed-free corn, yield loss occurred in each of seven site-years for weed communities established at VE corn, but in only one site-year for communities established at V2 corn. No corn yield loss was associated with weed communities established at V4 or V6 corn. For communities established at VE corn, predicted corn yield differed from observed yield in all but one site year, with predicted yield less than observed yield in three site-years, and greater than observed yield in two site-years; however, nonlinear regression analyses of yield data pooled over site-years showed that fitted values were similar between predicted and observed yield. For communities established at V2 and V4 corn, predicted yield was less than observed yield in six and five site-years, respectively. For communities established at V6 corn, predicted yield was less than observed yield in three of six site-years, but was similar to observed yield in three of six site-years. These results indicated that the CIM values in WeedSOFT tended to overestimate the competitiveness of late-emerging weed communities. Corn yield data from a pooled analysis of all site-years were used to generate a revised set of growth stage CIM values, which improved the accuracy of predicted corn yield. These results should improve weed management decisions and reduce the need for herbicide applications to late-emerging weeds.

Resumen

AbstractMany farmers and consumers are reevaluating chemical weed control because of the environmental risks of herbicides and their influence on farm size and diversity. This paper reviews research of the last 35 years on mechanical and cultural weed control in corn(Zea maysL.)and soybeans(Glycine maxL.).Soybeans can better use the weed control advantages of late planting and narrow row spacing and are less affected by early stand losses from mechanical weed control. In Minnesota, delaying planting to early June allows early germinating weeds to be controlled by preplant tillage but reduces the maximum yield potential of corn by approximately 25 percent and soybeans by approximately 10 percent. Narrow rows allow the crop canopy to close earlier, preventing emerging weeds from developing. However, in a nonchemical weed control system, the row spacing should allow for inter-row cultivation to control weeds that emerge with the crop. Up to a 10 percent reduction in crop stand may be expected in fields that have been rotary hoed. In Minnesota, a 10 percent stand loss results in a 2 percent loss of corn yield potential and no loss of soybean yield potential. Successful mechanical weed control is directly related to the timeliness of the operation. Rotary hoeing is effective on weeds that have germinated but not yet emerged but not on weeds that germinate from deeper than 5 cm, on no-till fields, or on fields with more than 20 to 30 percent crop residue. Inter-row cultivation is most effective on weeds up to 10 to 15 cm tall. Successful nonchemical weed control requires highly refined management skills and is as much an art as a science.

Resumen

The western corn rootworm, Diabrotica virgifera virgifera LeConte, is resistant to four separate classes of traditional insecticides, all Bacillius thuringiensis (Bt) toxins currently registered for commercial use, crop rotation, innate plant resistance factors, and even double-stranded RNA (dsRNA) targeting essential genes via environmental RNA interference (RNAi), which has not been sold commercially to date. Clearly, additional tools are needed as management options. In this review, we discuss the state-of-the-art knowledge about biotic factors influencing herbivore success, including host location and recognition, plant defensive traits, plant-microbe interactions, and herbivore-pathogens/predator interactions. We then translate this knowledge into potential new management tools and improved biological control.

Resumen

Maternal obesity and the use of assisted reproductive technologies (ART) are two suboptimal developmental environments that can lead to offspring obesity and cardiovascular disease. We hypothesized that these environments independently and synergistically adversely affect the offspring's weight and cardiovascular performance at ∼7 weeks of age. Mice were fed either 24% fat and 17.5% high-fructose (HF) corn syrup or maintenance chow (5% fat; low-fat, no-fructose (LF)). Dams were subdivided into no ART and ART groups. ART embryos were cultured in Whitten's medium and transferred into pseudopregnant recipients consuming the same diet as the donor. Offspring were fed the same diet as the mother. Body weights (BW) were measured weekly and mean arterial pressure (MAP) was collected through carotid artery catheterization at killing (55±0.5 days old). Expression of genes involved in cardiovascular remodeling was measured in thoracic aorta using qRT-PCR, and levels of reactive oxygen species (ROS) were measured intracellularly and extracellularly in mesenteric resistance arteries. ART resulted in increased BW at weaning. This effect decreased over time and diet was the predominant determinant of BW by killing. Males had greater MAP than females (P=0.002) and HF consumption was associated with greater MAP regardless of sex (P<0.05). Gene expression was affected by sex (P<0.05) and diet (P<0.1). Lastly, the use of ART resulted in offspring with increased intracellular ROS (P=0.05). In summary, exposure to an obesogenic diet pre- and/or post-natally affects weight, MAP, and gene expression while ART increases oxidative stress in mesenteric resistance arteries of juvenile offspring, no synergistic effects were observed.

Resumen

It was studied the feasibility of using corn cob to obtain a polymer composite. It was used of the corn cob in Three-grain sizes, and some formulations of the composite of polyester resin and powders were used, and the most appropriate formulation was chosen. For the characterization of the composite thermal and mechanical properties were determined. The main advantage of the composite was the low density, about 1.06 kg/m³ for the thick powder formulation. The composite presented an inferior mechanical behavior concerning the resin for all the studied particle sizes and formulations. The composite presented better mechanicals results for the bending strength, reaching 25.3 MPa for the thick powder formulation. The composite also proved itself to be viable for thermal applications since it has average thermal conductivity inferior to 0.21 W/m, being classified as thermal insulation and can be used to manufacture structures that do not require significant mechanical strength, such as tables, chairs, benches, panels, works of art, crafts and solar prototypes, such as ovens and stoves.

Resumen

A crescente demanda por combustíveis limpos e renováveis tem enfatizado o uso de fontes alternativas de energia como as biomassas lignocelulósicas. Esse tipo de resíduo é composto por carboidratos que se encontram em cadeias poliméricas e podem ser convertidos a etanol. Essa conversão representa o principal entrave para o uso dessas biomassas, visto que se necessita de um pré-tratamento para desestruturar a estrutura lignocelulósica, tornando-a suscetível ao ataque químico e enzimático e liberando glicose para fermentação etanólica. Nesse trabalho foi realizado um pré-tratamento ácido com sabugo e palha de milho, usando a ferramenta do planejamento experimental. Os fatores avaliados foram: tempo, temperatura e concentração de H2SO4, e como respostas: acidez e açúcares redutores totais (ART). Os maiores teores de ART são obtidos nos ensaios à 120°C, 15 min e 0,5% de H2SO4 e 110°C, 7 min, 2% de ácido tanto para o sabugo de milho como para palha de milho. Para essas condições, realizou-se hidrólise enzimática e fermentação. A maior eficiência fermentativa é dada na condição à 120°C, 15 min e 0,5% de H2SO4: 70,8% para o sabugo e 92,9% para a palha de milho.

Resumen

The first part of this study evaluates the occurrence of mycotoxin patterns in feedstuffs and fish feeds. Results were extrapolated from a large data pool derived from wheat (n = 857), corn (n = 725), soybean meal (n = 139) and fish feed (n = 44) samples in European countries and based on sample analyses by liquid chromatography/tandem mass spectrometry (LC-MS/MS) in the period between 2012–2019. Deoxynivalenol (DON) was readily present in corn (in 47% of the samples) > wheat (41%) > soybean meal (11%), and in aquafeeds (48%). Co-occurrence of mycotoxins was frequently observed in feedstuffs and aquafeed samples. For example, in corn, multi-mycotoxin occurrence was investigated by Spearman’s correlations and odd ratios, and both showed co-occurrence of DON with its acetylated forms (3-AcDON, 15-AcDON) as well as with zearalenone (ZEN). The second part of this study summarizes the existing knowledge on the effects of DON on farmed fish species and evaluates the risk of DON exposure in fish, based on data from in vivo studies. A meta-analytical approach aimed to estimate to which extent DON affects feed intake and growth performance in fish. Corn was identified as the ingredient with the highest risk of contamination with DON and its acetylated forms, which often cannot be detected by commonly used rapid detection methods in feed mills. Periodical state-of-the-art mycotoxin analyses are essential to detect the full spectrum of mycotoxins in fish feeds aimed to prevent detrimental effects on farmed fish and subsequent economic losses for fish farmers. Because levels below the stated regulatory limits can reduce feed intake and growth performance, our results show that the risk of DON contamination is underestimated in the aquaculture industry.

Resumen

Storage Potentials and Tolerance of High Protein Maize (HPM) and Quality Protein Maize (QPM) to Seed Storage Pests in Controlled EnvironmentStudies on seed storage were conducted at seed processing and storage section of the Institute of Agricultural Research and Training, Obafemi Awolowo University, Moor Plantation, Ibadan Nigeria in 2007 and 2008, to evaluate High protein maize (HPM) seed for resistance/tolerance to storage insect pest, and assess the resultant effect of seed treatment chemicals on its germination potential. Seeds of HPM variety (ART-98-SW1) and Quality protein maize (QPM) variety (ILE-1-OB) and two varieties of field corn (SUWAN-1-SR and TZPB-SRW) were treated with chemicals, namely Fitscophos™, Actellic 25 EC™, Apron Star™ and combination of Actellic 25 EC and Fitscophos before storing them under controlled environment for six months. The results show that HPM, QPM and field corn require storage chemicals for effective storage, but both QPM and HPM varieties were significantly damaged by storage insect pests compared to field corn varieties regardless of the chemical used. Apron Star effectively reduced infestation by insect pests, but it may bring about significant reduction in seed viability if used for long term storage. Combination of Actellic 25 EC and Fitscophos successfully reduced infestation by insect pests without significant injurious effect on seed viability. Breeding programmes for resistance to storage pests is recommended while long term effects of Apron Star on seed viability needs to be investigated before recommending it for use in HPM/QPM maize varieties.

Resumen

Big Noise – heard in London on 21 November and repeated at the Dome (Corn Exchange) in Brighton on the 22nd – was a collaboration between the highly idiosyncratic New Music ensembles Orkest de Volharding (Holland) and Icebreaker (UK). The former was established by the amazingly influential Dutch composer Louis Andriessen: reacting against the elitist music of his youth, he saw the need for a new type of Art-music ensemble which could travel into the streets and play music with a broad appeal. Borrowing from the model of Dutch street bands (the equivalent, perhaps, of the UK's brass bands), jazz of the 1920s, Minimal music coming out of America and the European avant-garde, Andriessen created an ensemble and a language with an overt non-elitist agenda.

Resumen

Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic materials, is one of the alternative energy resources, which is both renewable and environmentally friendly. Although, the priority in global future ethanol production is put on lignocellulosic processing, which is considered as one of the most promising second-generation biofuel technologies, the utilization of lignocellulosic material for fuel ethanol is still under improvement. Sugar-based (molasses, sugar cane, sugar beet) and starch-based (corn, wheat, triticale, potato, rice, etc.) feedstock are still currently predominant at the industrial level and they are, so far, economically favorable compared to lingocelluloses. Currently, approx. 80 % of total world ethanol production is obtained from the fermentation of simple sugars by yeast. In Serbia, one of the most suitable and available agricultural raw material for the industrial ethanol production are cereals such as corn, wheat and triticale. In addition, surpluses of this feedstock are being produced in our country constantly. In this paper, a brief review of the state of the art in bioethanol production and biomass availability is given, pointing out the progress possibilities on starch-based production. The progress possibilities are discussed in the domain of feedstock choice and pretreatment, optimization of fermentation, process integration and utilization of the process byproducts.

Resumen

Using reclaimed water from treated wastewater as an irrigation source is gaining popularity in arid and semi-arid areas. However, life cycle assessment studies, utilizing experimental data to analyze the environmental and health impacts of crops irrigated with reclaimed water, are lacking. This study presents the first comparative life cycle assessment of corn, soybean and wheat systems irrigated with groundwater and reclaimed water in Northern China. While the life cycle foreground inventory was based on a combination of experimental and modeling datasets, the life cycle background inventory was compiled with commercially available data packages augmented with Chinese electricity mix data. The life cycle impact analyses were based on the characterization factors from state-of-art life cycle impact assessment models. The analyses indicated that the life cycle global warming impacts of the crop systems ranged from 0.37 to 0.64 kg CO2-eq/kg grain, with reclaimed water irrigated soybean and ground water irrigated wheat exhibiting, respectively, the lowest and highest global warming impacts. Irrigation, farming equipment operation, on-field emissions and fertilizer production ranked as top contributors to the life cycle impacts for corn, soybean, and wheat. The comparative analyses of irrigation sources suggested that significant environmental tradeoffs existed. Replacing groundwater with reclaimed water as the irrigation source significantly decreased life cycle global warming, acidification, ozone depletion, smog formation, and respiratory impacts of corn, soybean and wheat systems. However, replacing groundwater with reclaimed water increased the life cycle noncancer impacts of those systems. Coordinating policies within the water–food–health nexus is required, in order to minimize the environmental tradeoffs, while maximizing the benefits of irrigation with reclaimed water.

Resumen

Due to the increasing demand for the monitoring of crop conditions and food production, it is a challenging and meaningful task to identify crops from remote sensing images. The state-of the-art crop classification models are mostly built on supervised classification models such as support vector machines (SVM), convolutional neural networks (CNN), and long- and short-term memory neural networks (LSTM). Meanwhile, as an unsupervised generative model, the adversarial generative network (GAN) is rarely used to complete classification tasks for agricultural applications. In this work, we propose a new method that combines GAN, CNN, and LSTM models to classify crops of corn and soybeans from remote sensing time-series images, in which GAN’s discriminator was used as the final classifier. The method is feasible on the condition that the training samples are small, and it fully takes advantage of spectral, spatial, and phenology features of crops from satellite data. The classification experiments were conducted on crops of corn, soybeans, and others. To verify the effectiveness of the proposed method, comparisons with models of SVM, SegNet, CNN, LSTM, and different combinations were also conducted. The results show that our method achieved the best classification results, with the Kappa coefficient of 0.7933 and overall accuracy of 0.86. Experiments in other study areas also demonstrate the extensibility of the proposed method.

Resumen

Abstract The 100th meridian bisects the Great Plains of the United States and effectively divides the continent into more arid western and less arid eastern halves and is well expressed in terms of vegetation, land hydrology, crops, and the farm economy. Here, it is considered how this arid–humid divide will change in intensity and location during the current century under rising greenhouse gases. It is first shown that state-of-the-art climate models from phase 5 of the Coupled Model Intercomparison Project generally underestimate the degree of aridity of the United States and simulate an arid–humid divide that is too diffuse. These biases are traced to excessive precipitation and evapotranspiration and inadequate blocking of eastward moisture flux by the Pacific coastal ranges and Rockies. Bias-corrected future projections are developed that modify observationally based measures of aridity by the model-projected fractional changes in aridity. Aridity increases across the United States, and the aridity gradient weakens. The main contributor to the changes is rising potential evapotranspiration, while changes in precipitation working alone increase aridity across the southern and decrease across the northern United States. The “effective 100th meridian” moves to the east as the century progresses. In the current farm economy, farm size and percent of county under rangelands increase and percent of cropland under corn decreases as aridity increases. Statistical relations between these quantities and the bias-corrected aridity projections suggest that, all else being equal (which it will not be), adjustment to changing environmental conditions would cause farm size and rangeland area to increase across the plains and percent of cropland under corn to decrease in the northern plains as the century advances.

Resumen

The industry of the 21st Century will be totally different from the one we experienced in the 19th and 20th centuries. It will be technology-intensive and energy-wise clean. The industry of the 21st century should be biodegradable and sustainable. Instead of transforming only products and raw materials it must transform the human beings. Brazilian agriculture with its technological advances and sophisticated production may be an important partner of the United States to create a new biological industry for the 21st Century. Brazil is the world’s leading producer of cotton, orange juice, chicken, beef, sugar, ethanol, biodiesel, soy, corn, among others. Brazil has the latest technology to genetically modify plants and animals. The United States is the world’s largest producer of many of the state-of-the-art technology products. Cooperation between the two countries in terms of genetic improvement of plants and animals has lasted for more than 40 years. Now, the next challenge is to invent a new industry and a new economy that can face the challenges ahead. These are some of the key gates to the bioeconomy.

Resumen

Abstract This experiment was conducted to assess the performance of Bacillus thuringiensis (Bt) transgenic corn hybrids (100- and 105-day RM) and comparable non-Bt hybrids against a natural ECB infestation in southwest Minnesota. Plots, each measuring 50 ft by 8 rows (30-inch row spacing), were established in Normania loam soil on 5 May at a rate ol 30,000 seeds per acre. Plots were arranged in a RCB with four replications. ECB injury assessments for first generations on 4 Aug included % shotholing from the center two rows of each plot and leaf injury ratings from 10 plants per plot. Tunnel length and number from both the first generation and univoltine generations were measured simultaneously from 10 plants per plot on 27 Aug. Measurements for second-generation ECB on 15-16 Oct included cumulative tunnel length and number, fall larvae, and ear and shank damage. Plots were harvested on 23 Oct and yields were corrected to 15.5% moisture.

Resumen

Abstract This experiment was conducted to assess the per formance of Bacillus thuringiensis transgenic corn hybrids (<95-day RM) and comparable non-Bt hybrids against a natural ECB infestation in west centra Minnesota. This area contains a mixture of univoltine and multivoltine biotypes. Treatments included 3 non-Bt hybrids (Ciba 4144, NK 2555, NK 3030) anc their isogenic counterparts (Max 357, NK 2555Bt, NK 3030Bt) arranged in a RCB design with 6 replications. Plots, each measuring 50 ft by 8 rows (30-inch row spacing), were planted on 19 May at a rate of 30,000 seeds per acre using a Hiniker Econo Till Planter. Planting preparations, fertilizer and herbicide ap plications followed normal production practices. First generation evaluations on 5 Aug included % of plants with leaf injury, leaf injury ratings (1 to 9 scale) number of tunnels, and tunnel length. Combined effects of univoltine and second generations were measured by examining tunnel number and length, ear anc shank infestations, and overwintering larvae on 20 Sept. Plots were harvested on 10 Oct and yields were corrected to 15.5% moisture.

Resumen

Abstract ‘Golden Queen’ sweet corn was seeded on 22 I Apr near Calabash, NC in Brunswick Co. Single-row plots, 10 ft long on 42-inch centers, were replicated 4 times in a RCB design. Alleys of 5 ft were used I between replicates. Treatments were applied with a CO2-pressurized backpack sprayer using a single hollow-cone nozzle (18X) operating at 60 psi to deliver 54.5 gpa. Test 1 and Test 2 were in the same field with a 75 ft spacing of untreated area between the two test sites. Applications were made to both Test 1 and Test 2 twice a week on 27 and 30 Jun, and 3, 7, 10, 14, and 17 Jul. Insect-damaged ears were assayed on 21 Jul when all ears were harvested from both tests.
