Nowadays, corn is an important source of nutrients in the human diet, as well as a valuable energy feed with the highest digestibility among cereals, a valuable raw material for the food, medical, microbiological, chemical industry and other sectors of the national economy. Increasing of corn grain production is one of the most important conditions for stabilizing the Russian food base. Being one of the technological crops that is demanding to growing conditions, corn is the most productive forage crop. It is important to note that the yield of corn depends not only on the fertility of the soil, but also on the methods of its processing and cultivation. One of the reasons holding back the growth of corn grain production is the high contamination of crops. In this paper, the influence of various cultivation technologies and methods of caring for maize crops on productivity is studied. It is shown that the highest yield and effective protection from weeds is obtained with an optimal combination of chemical and mechanical methods of crop care.

Abstract The paper deals with the issues of corn production and agricultural machinery used for this. It is noted that the ridge technology has the best environmental properties among the corn cultivation processes. The paper provides information about the main agro-engineering requirements when using this technology, its advantages and machines used for soil cultivation and sowing corn seeds. Particular attention is paid to the technological issues of harvesting corn for grain and engineering support of production processes, such as use of both dedicated corn harvesters and combine harvesters fitted with the necessary equipment including special corn attachments and reapers. Depending on the availability of technical equipment in agricultural enterprises, the ripeness and moisture content of the grain and other factors, a certain corn harvesting process is selected to obtain peeled cobs, unpeeled cobs or a grain and corncob mixture. The use of dedicated corn harvesters ensures obtaining peeled cobs. Harvesting when obtaining unpeeled cobs allows reducing grain losses, as well as labor and cost, and increasing the amount of corn leaf and stalk mass harvested. Both domestic harvesters and reapers, and those produced by foreign companies are used. This takes into account the manufacturability of the equipment, the possibility of maintenance, and economic factors.

Abstract The research was carried out in order to identify the best method of basic tillage in the cultivation of corn per silo in 2016-2019 on two experimental fields of the Tyumen region in two repeated experiments: factor A – soil cultivation methods (moldboard, nonmoldboard, differentiated), factor B – (without fertilizers, with the use of organic fertilizers – manure) in the first experiment, factor B – corn hybrids (Katerina SV, Ross 140 SV) in the second experiment. Sowing of corn was carried out in the second decade of May with a STV 8KU seeder. In the first experiment over the years of research, the best option was the moldboard method of processing with the introduction of organic fertilizers, where the highest yield was obtained – 39.9 t/ha. With refusal of organic fertilizers, the corn yield decreased by 10.5 t/ha for moldboard and by 9.3 t/ha for nonmoldboard methods. In the second experiment, the yield of corn hybrids over the years of research varied from 28.1 to 35.6 t/ha. The moldboard method was the best option for cultivating both hybrids, where the yield for Katerina SV hybrid is 35.6 t/ha, for the Ross 140 SV hybrid – 32.1 t/ha.

The Sungkai Permai Lambung Bukik Farmer Group, Padang City, generally cultivates in monoculture, with limited productive land. The land is planted with rice, secondary crops such as corn, and some peanuts. In the past two years, corn farmers often experience crop failures, especially during the rainy season, where the sun shines less due to global climate change. Therefore, diversifying commodities on limited land so that land efficiency increases are significant to prepare the next source of seeds. To support increased land use efficiency, optimal soil conditions are needed. Utilization of Arbuscular Mycorrhizal fungi can improve soil fertility and is expected to become an alternative technology in plant cultivation. Science and technology activities based on the Study Program and the Assisted Nagari (IbPSNB) were carried out in groups of Permai Sungkai Farmers in the form of 1) Counseling on the pattern of corn-peanut intercropping cultivation, and how to make CMA spore cultures, 2). The demonstration plot for corn-peanut intercropping cultivation. Through this activity, farmers finally understood the benefits and patterns of corn-peanut intercropping. Farmers understand the role and method of making CMA spore cultures. Several farmers cultivated corn-peanut intercropping. Two farmers at the demonstration plot managed to harvest corn and peanuts at the same time. Other farmers have failed to harvest corn due to pest attacks but have succeeded in harvesting peanuts so that the losses experienced by farmers are reduced, and they still have stock of seeds for the next planting season.

Despite new cultivation methods, the proportion of conventionally cultivated land is still very high in Hungary.Although these technologies demand more time, labour and fuel, they are still attractive to users because they require less professional skill and simple machinery. In Hungary, conventional tillage methods usually lead to soil deterioration, soil compaction and a decrease in organic content. These side effects have caused gradually strengthening economic and environmental problems.The technologies for those plants which are dominant on Hungarian arable lands use (winter wheat, maize, sunflower and barley) need to be improved both in the interest of environmental protection and the reduction of cultivation costs.The Department of Land Use at Debrecen University is cooperating with KITE Sc. to carry out soil tillage experiments at two pilot locations to prove tillage technologies already used in the USA.The aim of our examination is to adapt new technological developments and machinery, and to improve them on Hungarian soil for local environmental conditions. With these improved machines, the field growing of plants could be executed by less manipulation and better suited to economic and environmental needs. The most significant task is to investigate and improve the conventional cultivation replacing, new soil-protecting tillage technologies, and to apply no-till and mulch tillage systems.On the basis of the experiments’ survey data, we established that the looseness and moisture content of the soil using reduced tillage is more favourable than after using conventional technologies. The results of no-till and shallow spring tillage are behind those of winter plough or disk ripper cultivation in corn yield and production elements.To preserve moisture content in the soil, the ground clearing and sowing while simultaneously performing no-till method presents the most favourable results. The surplus moisture gained using no-till technology is equal to 40 mm precipitation.Regarding the yield of winter wheat we established that the tillage methods do not affect plant yield. Both disk ripper and conventional disc cultivation showed nearly the same harvest results (5.55 or 5.5 t/ha), where the difference is statistically hardly verifiable from the no-till method. From the individual production of corn and the number of plants planted in unit area, calculated results prove that no significant difference can be detected between the production of winter plough and disk ripper technology. Although the yield achieved with the no-till method is less than with the previously mentioned technologies, the difference is only 9-10%. We received the lowest production at shallow spring tillage.Evaluations have shown a 1.1 t/ha (13%) difference in the yield of maize, between winter tillage and the disk ripper method, in this case the traditional method resulted in higher yield. In winter tillage, the yield of maize was 1.9-2.1 t/ha (23-25%) higher than in the case of direct sowing and cultivator treatments. No significant difference could be noted between the yields of direct sowing and cultivator treatments.Our research so far has proved the industrial application of reduced tillage methods in crop cultivation technologies.

Abstract Increasing corn production is usually done by increasing the planting area (including intercropping) and applying technology. The technology applied to increase productivity is integrated crop management and the application of climate change adaptation and mitigation. One of the technology components is the management of organic fertilizers with the use of biodecomposers in the area of land to be planted. One of the biodecomposers is Agrodeco™ from the Agricultural Research and Development Agency. Agrodeko is a consortium biodecomposer from Trichoderma fungal strains, N-fixing in the form of non-pathogenic yeast and Candida sp which grows fast and is able to produce enzymes needed to decompose plant tissue. While the varieties grown in a development area can be used composite corn. The activity was carried out in Jeron Village from June to October 2017. Planting area for activities is around 4000 m2. There were 3 (three) treatments applied, namely cropping patterns (monoculture and intercropping), corn varieties (Srikandi Kuning and Provit A) and fertilizer doses (farmer's dose and recommended dose (with Agrodeco™ application)). In monoculture cropping system, yields were not significantly different between Srikandi Kuning and Provit A, but the productivity of Provit A (3.8 tons/ha) was higher than Srikandi Kuning (3.4 tons/ha). In the intercropping system, the productivity of Provit A corn at the farmer dose treatment (1.2 tons/ha) was significantly different from the recommended fertilizer dose treatment (2.2 tons/ha.

Abstract The research was carried out at the experimental field of the North Caucasus Federal Research Center. In the field, years of experience, founded in 2012, in crop rotation of soybean-winter wheat-sunflower-corn all crops cultivated on the recommended scientific institutions technology soil treatment, and these same crops in the same crop turnover has grown by No-till technology. The recommended technology of maize cultivation consisted of soil double tillage by the heavy disk tools to the depth of 0.120-0.140 m immediately after harvesting the previous sunflower, winter plowing at 0.200-0.220 m, early spring harrowing, pre-sowing cultivation and sowing with an Optima seeder. In the No-till technology, the soil was not treated and ten days before corn sowing, the plots were sprayed with a continuous herbicide Rap 600 at a dose of 2 l/ha. The research showed that better accumulation and conservation of moisture can be provided during the flowering of maize with the content in the soil layer of 1.5 m at the depth of 34 mm, or 18.1% more moisture than usage of the technology with tillage which is recommended by scientific institutions. It contributes to a significant increase of 0.42 t/ha, or 12.0% in crop yield by using this technology.

Recent socioeconomic development, increased transport and new agricultural technology are endangering the survival of traditional agriculture and the Yi people’s traditional knowledge of cultivating Tartary buckwheat. The cultural heritage of Tartary buckwheat cultivation among the Yi communities needs to be investigated and protected before its loss. The main objectives of this study are to document the Tartary buckwheat cultivation system, to analyze the agroecosystem networks that support the current system, and to measure the resilience of the ecological, agricultural and social systems using relevant indicators. The Tartary buckwheat cultivation system in Meigu County uses a rotation system, in which various crops are planted alternatively (e.g., Tartary buckwheat, green manure and potato/corn), utilizing bunch planting and furrow drilling technology. Tartary buckwheat has an important position in the major festival activities among the Yi people’s communities. Network analysis on the current agricultural system, ecosystem and social system indicated that the system was stable. The mean score of ecological, agricultural and social stability were 2.50, 2.85 and 2.53, respectively, indicating moderately stability. In contrast, socio-ecological production landscapes and seascapes (SEPLS) resilience indicators in Meigu performed only moderately, with a score of 2.63. The assessment of the resilience of the Tartary buckwheat cultivation system can provide some guidance for policy makers to strengthen biodiversity conservation, sustainable agricultural production and livelihood development (e.g., land use, responding to extreme environmental stresses and improving education levels).

An in situ technology for mitigating diffuse agricultural pollution using catch crops was developed for simultaneously preventing nitrate groundwater pollution, reducing nitrous oxide (N2O) gas emissions, and removing salts from the topsoil. Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d cultivation of dent corn. Catch crop cultivation significantly reduced the leached mineral nitrogen by 89–91% in summer, 87–89% in spring, and 61–82% in winter, and it also significantly reduced the N2O emission by 68–84% in summer. The amounts of nitrogen uptake by the catch crop were remarkably higher than those of leached nitrogen and N2O emission in each season. Catch crop cultivation is a promising technology for mitigating diffuse agricultural pollution.

Full textAbstract:
The necessity of application of hybrid specific crop production technology has been confirmed not only by trial results but also by the experiences gained from the agricultural practice. For this reason it is essential to test and collect data in field trials about the specific agronomic traits of the corn hybrids belonging to different maturity groups and genotypes. Corn hybrids are tested for their responses to sowing time, plant density and fertilizer supply; sensitivity to herbicides; and lately, the resistance to the damages caused by the larvae of corn root worm. Last but not least, mention should be made of the differences in the responses of the corn hybrids to the damages caused by drought stress. Based on the trial results, suggestions for the hybrid specific corn production are compiled and made public for the experts and farmers engaged in corn growing. Corn hybrids may deliver maximum yields on the impact of specific crop production technology only in case if it relies on carefully done general production technology including soil cultivation, seed bed preparation and weed control. Similarly, precision crop production technology may advance the yield increase in economic way if it is constantly drawing on the source of research results.

Abstract The yield and quality of corn grain is significantly affected by the infection of plants with diseases of agricultural crops. The susceptibility of corn bioagrocenoses of hybrids ROSS 145 MV, ROSS 140 SV, Povolzhsky 107 SV, Katerina SV, NC Falcon, NC Gitago and Delitop to diseases during their cultivation for grain according to traditional, minimal and no-till technology in the agro-climatic conditions of the Volga-Vyatka region was studied. In the course of research, it was found that the most common diseases of corn due to excessive moisture in the soil and high humidity during the harvest period are mildew on the cob, fusarium on the cob, root and stem rot, dust and blister smut. Under unfavorable harvesting conditions, the incidence can reach 40 %. Under favorable weather conditions, there are isolated cases of plant diseases, regardless of the cultivation technology. To protect the bioagrocenoses of corn, it is necessary to grow disease-resistant hybrids, monitor the rotation of crops in the crop rotation, apply full doses of mineral fertilizers and micronutrients, sow at the optimum time with an appropriate seeding depth, maintain a complex chemical plant protection system, starting with seed dressing. The closest to the requirements are zoned maize hybrids with a short growing season ROSS 145 MV, ROSS 140 SV, Povolzhsky 107 SV and Katerina SV.

Artificial neural networks and linear regression are widely used in particularly all branches of science for modeling and prediction. Linear regression is an old data processing tool, and artificial neural networks are a comparatively new one. The goal of the study was to determine whether artificial neural networks are more accurate than linear regression in sweet corn yield prediction. In the study we used a dataset obtained from field experiments on the technological improvement of sweet corn cultivation. The field experiments were conducted during the period from 2014 to 2016 on dark-chestnut soil under drip irrigated conditions in the Steppe Zone of Ukraine. We studied the impact of the moldboard plowing depths, mineral fertilizer application rates and plant densities on the crop yield. A significant impact of all the studied factors on the sweet corn productivity was proved by using the analysis of variance. The highest yield of sweet corn ears without husks (10.93 t ha–1) was under the moldboard plowing at the depth of 20–22 cm, mineral fertilizers application rate of N120P120, plant density of 65,000 plants ha–1. Data processing by using the linear regression and artificial neural network methods showed that the latter is a great deal better than linear regression in sweet corn yield prediction. Higher accuracy of the artificial neural network prediction was proved by the higher value of the coefficient of determination (R2) – 0.978, in comparison to 0.897 for the linear regression prediction model. We conclude that artificial neural networks are a much better data processing tool, especially, in the life sciences and for prediction of the non-linear natural processes and phenomena. The main disadvantage of the neural network models is their “black box” nature. However, linear regression will not lose its popularity among scientists in the nearest future. Linear regression is a much simpler data analysis tool, it is easier to perform the prediction, but it still provides a sufficiently high level of accuracy.

<p>We determined that the structure of phytocenosis of weeds in corn crops caused by the influence of their adaptive ability and structure of crop areas in crop rotation. The basis of the dominance of weeds in the species structure is the resistance to herbicides, wide range of similarity, morphological plasticity, and the presence of non-toxic signs. The application of the technology of corn cultivation of small, non-field multicultural soil cultivation (chiseling, flattening loosening) leads to strong increase in the level of permeation by 1.4-1.8 times, which in turn requires the additional rules for soil treatment and postemerged herbicides that reliably control the corn productivity. It has been proved that field plowing and chiseling together with the introduction of the N<sub>30</sub>P<sub>30</sub>K<sub>30</sub> had minimal advantage on the corn grain yields in non-fertilized conditions due to better nutritional conditions and lower levels of perennial crops. The most effective soil treatment was the shallow and flattening loosening of the chip which under increase of nitrogen content (N60P30K30) caused by corn fertilization allows us to obtain the same yield concerning the plowing and chiseling. The methods of basic soil cultivation under low level of feed infestation (9.0-12.6 pieces/m²) did not have significant effect on the quality of corn grain. The introduction of mineral fertilizers (especially nitrogen) increases the tendency to increase the protein content in the grain (proteins) and reduce the content of carbohydrates, especially the starch.</p>

Studies of the influence of different technologies of ordinary chernozem cultivation on the reserves of productive moisture for growing corn for grain and winter wheat in the steppe zone of Ukraine The parameters of productive moisture at the technology of growing field crops with "zero tillage" of the soil ("No-till") relative to the shelf plowing are determined. Inserted. That the system "No-till" contributes to a significant reduction in moisture loss due to unproductive evaporation at a high rate of absorption of precipitation, provides reliable protection of soil from erosion. When covering the soil surface close to 100% in summer under corn, the reserves of productive moisture in the root layer are 1.5 and more times higher than the corresponding reserves with traditional technology; in the absence of mulch, the humidification regime with the technology without tillage is more intense than traditional. The regime of soil moisture under winter wheat for corn for silage is better by "zero" technology, but no significant difference between the options for an average of 3 years. In the snowless winter with "zero" technology with mulch, the height of snow cover was 3.2 times higher than traditional technology. It was found that a prerequisite for growing crops without tillage in the area of insufficient moisture is the creation of a thick layer of mulch due to the non-commodity share of crop yields, which in crushed form remains on the soil surface. Projective mulch coverage of 100% or close to this level is the key to the widespread introduction of cultivation technologies without tillage in arid steppe conditions.

South Korea’s agriculture is characterized by a mixture of various cultivated crops. In such an agricultural environment, convergence technology for ICT (information, communications, and technology) and AI (artificial intelligence) as well as agriculture is required to classify objects and predict yields. In general, the classification of paddy fields and field boundaries takes a lot of time and effort. The Farm Map was developed to clearly demarcate and classify the boundaries of paddy fields and fields in Korea. Therefore, this study tried to minimize the time and effort required to divide paddy fields and fields through the application of the Farm Map. To improve the fact that UAV image processing for a wide area requires a lot of time and effort to classify objects, we suggest a method for optimizing cultivated crop recognition. This study aimed to evaluate the applicability and effectiveness of machine learning classification techniques using a Farm Map in object-based mapping of agricultural land using unmanned aerial vehicles (UAVs). In this study, the advanced function selection method for object classification is to improve classification accuracy by using two types of classifiers, support vector machine (SVM) and random forest (RF). As a result of classification by applying a Farm Map-based SVM algorithm to wide-area UAV images, producer’s accuracy (PA) was 81.68%, user’s accuracy (UA) was 75.09%, the Kappa coefficient was 0.77, and the F-measure was 0.78. The results of classification by the Farm Map-based RF algorithm were as follows: PA of 96.58%, UA of 92.27%, a Kappa coefficient of 0.94, and the F-measure of 0.94. In the cultivation environment in which various crops were mixed, the corn cultivation area was estimated to be 96.54 ha by SVM, showing an accuracy of 90.27%. RF provided an estimate of 98.77 ha and showed an accuracy of 92.36%, which was higher than that of SVM. As a result of using the Farm Map for the object-based classification method, the agricultural land classification showed a higher efficiency in terms of time than the existing object classification method. Most importantly, it was confirmed that the efficiency of data processing can be increased by minimizing the possibility of misclassification in the obtained results. The obtained results confirmed that rapid and reliable analysis is possible when the cultivated area of crops is identified using UAV images, a Farm Map, and machine learning.

Full textAbstract:
Atrazine has been the most widely used herbicide in North American processing sweet corn for decades; however, increased restrictions in recent years have reduced or eliminated atrazine use in certain production areas. The objective of this study was to identify the best stakeholder-derived weed management alternatives to atrazine in processing sweet corn. In field trials throughout the major production areas of processing sweet corn, including three states over 4 yr, 12 atrazine-free weed management treatments were compared to three standard atrazine-containing treatments and a weed-free check. Treatments varied with respect to herbicide mode of action, herbicide application timing, and interrow cultivation. All treatments included a PRE application of dimethenamid. No single weed species occurred across all sites; however, weeds observed in two or more sites included common lambsquarters, giant ragweed, morningglory species, velvetleaf, and wild-proso millet. Standard treatments containing both atrazine and mesotrione POST provided the most efficacious weed control among treatments and resulted in crop yields comparable to the weed-free check, thus demonstrating the value of atrazine in sweet corn production systems. Timely interrow cultivation in atrazine-free treatments did not consistently improve weed control. Only two atrazine-free treatments consistently resulted in weed control and crop yield comparable to standard treatments with atrazine POST: treatments with tembotrione POST either with or without interrow cultivation. Additional atrazine-free treatments with topramezone applied POST worked well in Oregon where small-seeded weed species were prevalent. This work demonstrates that certain atrazine-free weed management systems, based on input from the sweet corn growers and processors who would adopt this technology, are comparable in performance to standard atrazine-containing weed management systems.

The article presents the results of studying the impact of foliar fertilization with Ekolist Mono Zinc microfertilizer on the complex of economically valuable traits and productivity of maize hybrids of different maturity groups. The research has been conducted for studying the dependence of the timing of foliar fertilization on the level of productivity of corn. Field research was established during 2019-2020 in the research field of the Department of Plant Breeding, Breeding and Bioenergy Crops of SE "Kordelivske" IC NAANU Vinnytsia National Agrarian University. The soil of the experimental site - dark gray is characterized by the following agrochemical parameters: humus content - 3.27%, nitrogen supply (by the method of Cornfield) low - 116 mg / kg of soil, mobile phosphorus compounds (by Chyrykov method) average - 95 mg / kg of soil , and high potassium - 137 mg / kg of soil, pH - 6.5. A two-factor experiment with corn was established by the method of split plots. The study was performed in quadruplicate. The sown area of the plot is 50 m2, the accounting area is 25 m2. Observations and crop accounting were performed according to generally accepted methods. Studies have shown that the largest increase in plant height (11-18 cm) and the height of attachment of cobs was observed in variants with two foliar feeding of corn with microfertilizer Ecolist Mono Zinc. Application of Ekolist Mono Zinc microfertilizer in the phase of 5-7 and 10-12 corn leaves provides the highest value of cob length: DKS 2971 (FAO 200) - 22.0 cm, DKS 3476 (FAO 260) - 25.2 cm and DKS 3511 330) - 26.0 cm, increases the weight of 1000 grains by 7.5-12.4%, protein content by 0.07-0.15%, reduces the fat content by 0.01-0.20% compared with the control. The highest value of yield of the studied maize hybrids was obtained by double application of microfertilizer Ecolist Mono Zinc in the phase of 5-7 and 10-12 leaves of corn, and on average for two years it was: DKS 2971 (FAO 200) - 7.5 t / ha, DKS 3476 (FAO 260) - 9.8 t / ha and DKS 3511 (FAO 330) - 10.4 t / ha, while the control yield was 6.6; 8.8 and 9.0 t / ha, respectively. Taking into consideration the results of the analysis of economic indicators of cultivation of maize hybrid DKS 3511 (FAO 330), the highest value of gross production per 1 ha - 41.44 thousand UAH / ha - was obtained on the option with double application of microfertilizer Ecolist Mono Zinc in phase 5-7 and 10-12 leaves of corn, the lowest cost of grain is set - 156.5 UAH / c. The final indicator of economic efficiency - the level of profitability - was the highest and amounted to 254.5%. Thus, foliar fertilization increases the yield of maize hybrids of different maturity groups, improves the quality of grain in terms of chemical composition and optimizes the value of economically valuable traits.

Full textAbstract:
Cultivating coccolithophore algae for carbon sequestration is discussed. Coccolithophores have been major calcium carbonate producers in the world’s oceans for about 250 million years. Today, they account for about a third of the total marine CaCO3 production by coating their single cells externally with plates of microcrystalline CaCO3. The possibility that these algae could be used to trap atmospheric CO2 with existing technology has not been widely considered. There is scope for both high technology cultivation in bioreactors and low technology cultivation in terraced raceway ponds or lagoons on tropical coastal sites. The latter could produce a sludge of pure CaCO3 as a feedstock for cement production in place of the fossilised limestone currently used (cement production accounts for around 8% of industrial fossil CO2 emissions). On the high seas coccolithophores naturally produce extensive blooms, which emit the volatile gas dimethyl sulfide to the atmosphere, where it promotes formation of clouds that block solar radiation. The vision is for aquaculture nurseries onboard factory ships, cultivating both coccolithophores and bivalve molluscs, creating and maintaining blooms of coccolithophores in the oceanic high seas to sequester carbon from the atmosphere and generate cloud cover to cool the immediate environment.

The article says that the main increase in the productivity of animal husbandry is to increase the production of feed and improve their quality. This is primarily due to the cultivation in each soil and climate zone of such crops that would provide high-quality and stable yields of forage crops. An alternative to traditional silage crops, such as corn, can be sugar sorghum. This is due to the versatility of its use, drought resistance, heat resistance and high productivity. Sorghum cultivation allows to increase the productivity of arable land and significantly improve the quality of feed in terms of sugar content. Therefore, the relevance of the full-scale study of the elements of the technology of forage crop cultivation, for the conditions of the Kazakh part of the Aral Sea region, is obvious. In the arsenal of the world’s plant resources, sorghum is characterized by the greatest heat and drought resistance, salt tolerance and high yield. To create a unit of dry matter, sorghum consumes almost half of its water. First of all, sorghum has a minimum transpiration coefficient, i.e. the water consumption is a unit of dry matter. For example, sorghum consumes 300 parts of water, and Sudanese grass – 340, corn – 388, wheat – 515, sunflower – 895. The yield of dry matter from sorghum is 30 % higher compared to corn. Sorghum grain contains more than 70-91 % starch and 10.5 % protein, and corn, respectively, 60-75 and 7-15 %. With an intensive type of root system development, sorghum belongs to the xerophytic (drought-resistant) type of plants. Sorghum is the leading crop among most crops due to its ability to tolerate prolonged harsh hydrothermal conditions.

The distribution of corn cultivation areas is crucial for ensuring food security, eradicating hunger, adjusting crop structures, and managing water resources. The emergence of high-resolution images, such as Sentinel-1 and Sentinel-2, enables the identification of corn at the field scale, and these images can be applied on a large scale with the support of cloud computing technology. Hebei Province is the major production area of corn in China, and faces serious groundwater overexploitation due to irrigation. Corn was mapped using multitemporal synthetic aperture radar (SAR) and optical images in the Google Earth Engine (GEE) cloud platform. A total of 1712 scenes of Sentinel-2 data and 206 scenes of Sentinel-1 data acquired from June to October 2017 were processed to composite image metrics as input to a random forest (RF) classifier. To avoid speckle noise in the classification results, the pixel-based classification result was integrated with the object segmentation boundary completed in eCognition software to generate an object-based corn map according to crop intensity. The results indicated that the approach using multitemporal SAR and optical images in the GEE cloud platform is reliable for corn mapping. The corn map had a high F1-Score of 90.08% and overall accuracy of 89.89% according to the test dataset, which was not involved in model training. The corn area estimated from optical and SAR images was well correlated with the census data, with an R2 = 0.91 and a root mean square error (RMSE) of 470.90 km2. The results of the corn map are expected to provide detailed information for optimizing crop structure and water management, which are critical issues in this region.

Perennial crops need far less energy to plant, require less fertilizer and pesticides, and show a lower negative environmental impact compared with annual crops like for example corn. This makes the cultivation of perennial crops as energy crops more sustainable than the use of annual crops. The conversion into biogas in anaerobic digestion plants shows however much lower specific methane yields for the raw perennial crops like miscanthus and willow due to their lignocellulosic structure. Without pretreatment the net energy gain is therefore lower for the perennials than for corn. When applying wet oxidation to the perennial crops, however, the specific methane yield increases significantly and the ratio of energy output to input and of costs to benefit for the whole chain of biomass supply and conversion into biogas becomes higher than for corn. This will make the use of perennial crops as energy crops competitive to the use of corn and this combination will make the production of biogas from energy crops more sustainable.

Modern environmental requirements for reclamation systems prioritize the reduction of the negative impact of irrigation on the environment. In the complex of various reclamation measures, an important role in solving these problems is played by the development and improvement of fundamentally new technical means and methods of irrigation. In the field of irrigated agriculture, this is reflected in the use and improvement of sprinkler machines and stationary installations that operate at reduced heads and comply with environmental safety requirements. At present, at the enterprises of the agro-industrial complex of Russia, great importance is attached to the choice of environmentally friendly and cost-effective technologies and technical means of irrigation. Drip irrigation and K.O. + MDD have an advantage over sprinkler irrigation in many economic indicators. Calculations show that in the long term, due to more economically beneficial technical solutions when creating a system, it is possible to reduce the amount of capital investment, and its widespread use in production will reduce maintenance costs. An analysis of research from an ecological and economic standpoint showed that in agricultural production it is necessary to master low-volume irrigation systems, which include drip, subsurface aerosol irrigation, as well as their combination or combination with other irrigation methods. Sprinkler irrigation technologies, which are most widespread in developed countries, should be aimed at reducing the intensity of rain drops, to preserve the fertile soil layer and protect plants, and, most importantly, to conserve energy and water resources.

This paper describes the results of data analysis on species composition and population of ground beetles (Coleoptera, Carabidae) in agrocenoses of spring wheat and corn at different levels of intensification in the forest-steppe of Western Siberia in the period of 2019-2021. The research was aimed at identifying correlating factors with the abundance of ground beetle communities and assessing their significance. The data analysis methods were specified with regard to the peculiarities of the structure and nature of the initial data distribution. Analysis of the population dynamics was performed for 20 species common and abundant for all agrocenoses (represented by dominants and subdominants). A position of the crop in the crop rotation was a significant factor for the agrocenoses of spring wheat, given that the distance from the steam increases the total biomass of vegetation due to weeds, as well as the number of pests, which probably forms more favorable conditions for the activity of ground beetles. Another correlation was also established between the index of dynamic density of ground beetles in wheat crops and the sum of active temperatures (t>5 ºC), revealing the significant role of heat supply for poikilothermic organisms. The correlation between the index of dynamic density of ground beetles and the vegetation index NDVI values in corn pointed to the features of microclimate formation, given the biology of corn and the ability to build up a large volume of biomass already by mid-summer. No significant correlation between the technology of cultivation (level of intensification) and the dynamic density of ground beetles in agrocenoses was found. Therefore, the level of intensification (the use of crop protection agents and fertilizers regulated by the cultivation technology) does not have a significant effect on the number of ground beetles in the crops.

Abstract. The production of corn in the North Caucasus, and particularly in Adygea, has its own characteristics. While cultivating, it is necessary to improve individual elements of technology constantly, since they, together with technical means, determine production efficiency, seed productivity and quality of product [7]. The purpose of the work is to determine the optimal methods of basic soil cultivation and doses of mineral fertilizers that give the maximum effect when growing corn selection hybrids of the FSBSI “National Grain Center named after P. P. Lukyanenko”. The novelty of the obtained results is that the responsiveness of new corn hybrids has been studied for the first time on merged leached black soils and the most optimal elements of their cultivation technology have been identified. The research methods correspond to the “Methodology of Experimental Business” by B. A. Dospekhov. Results. As a result, it was found that the types of tillage did not have a significant effect on the density of the topsoil and varied within 1.23–1.26 g/cm3. It was noted that the best conditions for the growth and development of plants are formed when fertilizers are applied at doses of N120P60K40 and N150P60K40. Plowing to a depth of 30–32 cm (option 3) and plowing to a depth of 26–28 cm with soil deepening (option 4) had approximately the same effect on the analyzed parameters of corn. The maximum leaf area in the range of 7028–7083 cm2 and the largest weight of one plant, 2.25–2.26 kg, was noted respectively in 3 and 4 options, which contributed to obtaining of the highest yield – 5.84 and 5.62 t/ha. The optimal parameters of the elements in the yield structure were noted in the variant with a dose of N120P60K40, where the grain yield of the hybrid ROSS 140 SV was 4.94 t/ha, Krasnodar 194 MV – 4.90 and ROSS 195 MV – 5.25 t/ha, which is on 67.2, 72.6 and 69.0 % higher than in the control. The use of fertilizers in a dose of N120P60K40 provides better economic efficiency, although the yield here is somewhat lower than on the N150P60K40 option. The most cost-effective was the variant with the dose of N120P60K40, and amounted: ROSS 140 SV – 168.6 %, Krasnodar 194 MV – 184.4 % and ROSS 195 MV – 185.4 %.

Corn is a highly productive crop of universal purpose, which is grown for food – 20–25 %, forage – 60–65 and technical purposes – 15–20 %. Increasing its yield is possible due to the improvement of the elements of the technology of cultivation taking into account biological characteristics. The growth and development of corn, the production of high yields, as well as the improvement of the quality of the main products are determined by factors of anthropogenic origin and weather conditions. Hydrothermal conditions of Ukraine have already begun to change significantly during the last decades, which resulted in a shift in the climatic seasons, changes in the vegetation period duration (depending on the zone and the biological features of the crops it can either decrease or expand), the decrease in the duration of a stable snow cover, changes in water resources of local drainage. The period 2005–2016 was analyzed for the reliable estimation of the typicality of weather conditions and their influence on the corn productivity under the following basic cultivation methods: ploughing at the depth of 28–30 cm (control), flat-cut tilling at the depth of 28–30 сm, chisel ploughing at the depth of 43–45 cm and disking at the depth of 10–12 cm. The dynamics of precipitation in the northern part of the Right Bank Forest Steppe during the corn vegetation period for the last 2005–2016 testifies to the noticeable tendency of increasing the amount of precipitation in May-June and their sharp decrease in July-August. It was determined that the conditions for eight years – 2006–2008, 2011–2014 and 2016 were optimal for their hydrothermal indices for the production of corn yields at the level of 5.83–9.47 t/ha. The hydrothermal coefficient for vegetation was 1.13–1.76. Weather conditions were unfavorable in 2005, 2009–2010, and 2015 with the amount of precipitation for vegetation of 120–288 mm, which is below the long-term amount by 120 mm, or 36 %. The peculiarity of these years was 37–61 % lower precipitation level in June–July with the grain yield of 3.12–6.51 t/ha. The mathematical-statistical analysis allows to characterize features and typicality of weather conditions of 2005–2016 and to estimate the influence of hydrothermal years and separate months on corn crops productivity. It has been established that there is the following correlation between weather conditions in July and the yield of corn: high correlation for disk soil cultivation (r=0.75–0.86), the average – for ploughing and chyzel loosening (r=0.49–0.53). Thus, the formation of a deep layer of soil with the best water–physical characteristics and fertility in these cultivation modes reduced the dependence of the elements of yield formation from the adverse weather conditions and provided a higher yield of corn by 6.0–8.0 %. Key words: hydrothermal conditions, hydrothermal coefficient (HTC), vegetation period, corn yield.

Subject of research. Biopesticides are based on live cultures of specially selected beneficial microorganisms with controlled properties. They have a pronounced phytoprotective and stimulating effect, thus providing effective prevention and protection of plants from diseases. The obtained biological product increases productivity, improves the quality and structure of the crop, does not accumulate in plants, which allows to obtain environmentally friendly agricultural products and does not harm the environment. Among the large number of bacteria, as a source of microbiological insecticide is Bacillus thuringiensis, which infects lepidopteran pests and leads to their death. Preparations based on this strain are effective when used in low concentrations of solutions. The Bacillus thuringiensis strain produces several toxins with insecticidal action, including β-exotoxin and δ-endotoxin. Toxic effect is manifested and leads to paralysis of the intestinal tract of parasites. Preparations β-exotoxin and δ-endotoxin are obtained by culturing Bacillus thuringiensis bacteria in a liquid medium. The scientific work proposes a method of industrial production using by-products of vegetable raw materials, which makes it economically feasible to use such substrates. The purpose of the study is the development of technology, formulation of nutrient medium, process parameters for the cultivation of bacteria of the genus Bacillus thuringiensis and obtaining a culture fluid containing substances of the class of biopesticides. Methods. Standard and generally accepted methods of research of bioproducts in biotechnology. The formation of bioinsecticides was established by hydrolysis methods, followed by determination of the component of β-exotoxin – ribose, the formation of octagonal crystals of exotoxin – by microscopic method. Research results. Three variants of nutrient media, which include yeast-polysaccharide complex: corn flour, corn oil, yeast autolysate were developed. The parameters of the bacterial cultivation process were studied. The final product is a paste or powder with a titer of 35 .109 spores in 1 g of the bioproduct. Scope of research results. Microbiological preparations based on Bacillus thuringiensis are highly specific and act only on insect larvae from the classes Lepidoptera and Diptera. The resulting biopesticide can be used against pests of a wide range of vegetable and fruit crops.

Abstract North Sulawesi is one of the areas with great potential in supporting the production and productivity of hybrid maize seeds. The land available for the cultivation of hybrid maize seeds is very wide, the requirements for agro-climatic are simple, the technology is readily available, so that the prospect of profits for the cultivator is quite large. Most of the maize farmers in North Sulawesi tend to use hybrid seeds. This is because the yield obtained is very high, however, the availability of hybrid seeds is very limited, even if available, the price is quite expensive. Farmers are currently still dependent on seed assistance from the Government. Production of seeds through breeder farmers as a solution in order to increase corn production. NASA 29 variety is a new superior variety derived from male parents G102612 and Mal 03 as female parents. The results of the interview showed that 86% of the 25 respondents of maize farmers gave an average rating score of 3.8. This shows that they really like the characteristics of the plant. The production data for NASA 29 seed candidates is 3.6 tons / ha. These results indicate that the prospect of hybrid maize seeding business is profitable for breeder farmers.

Corn is one of the important food crops and feeds in the world. Conversion of agricultural land into non-agricultural land is one of the major causes of the decline in corn production. Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. This technology can prevent pyrite oxidation in the tidal swamp. This research aimed to study the effect of temporary fl ooding under saturated soil culture on the growth and productivity of corn. The research was conducted at Karya Bhakti village, Rantau Rasau, Tanjung Jabung Timur, Jambi Province, Indonesia. The experiment used a split plot design with three replications. The main plot is fl ooding condition, consisted of 1) saturated soil condition continuously, from planting until harvesting time (as control), and 2) saturated soil condition from 0 to 10 DAP (Days after Planting) + fl ooding from 11 to 13 DAP + saturated soil condition from 14 to 28 DAP + fl ooding from 29-31 DAP + saturated soil condition from 32 DAP until harvesting time. The subplot is corn variety, “Sukmaraga”, “Bisma”, “Pioneer 27”, and “Bima 20”. “Pioneer 27” had the highest productivity of 9.33 t.ha-1. Corn varieties with moderate tolerance to temporary fl ooding were “Sukmaraga” and “Bisma”, whereas “Pioneer 27” and “Bima 20” are sensitive to fl ooding.

Abstract Presents results of a study of the uniformity of distribution of irrigation water along the length of the drip lines at its pre-treatment in sand gravel and disc filters (typical) and hydrocyclone installation (experimental version) and the efficiency of water technology in the cultivation of corn. It was found that when using a sand-gravel and disc filter as a water treatment unit on a drip irrigation system, the coefficient of effective irrigation was 0.635, insufficient irrigation - 0.240, and excessive irrigation - 0.125. The use of hydrocyclone installation for water treatment, which combines the processes of capture of dispersed particles by the method of sedimentation in a centrifugal field and the filtration method provides an increase of the coefficient of effective irrigation to 0.715 and reduce the rates of under-and over-irrigation, respectively, to 0.20 and 0.085. Thus, increasing the uniformity of the distribution of irrigation water along the length of the drip lines ensures the regulation of irrigation of agricultural crops. In field experiments on corn cultivation with drip irrigation, an increase in grain yield was achieved by 9% when using an experimental version of the water treatment unit instead of the standard one on the irrigation system.

Community service programs are implemented to solve problems after corn is harvested, this problem is faced by partner groups. The dependence of partners on traders who provide loans in the form of agricultural production facilities, makes farmers' incomes low. The provision of multifunctional machine technology, socialization, demonstration, and training is expected to be able to overcome the problems. Data processing using the Likert Summated Rating Scale (LSRS) with numbers 1-5 from the very poor to very knowing category. The ability of farmers to use machines after harvesting corn is categorized as understanding. All members of the farmer group understand and are able to operate the corn sheller machine owned by the traders, but at the time of operating the multifunction machine only some farmers are able and understand the operation of the machine. Demonstrations involve partners in the preparation, operation and production of multifunctional machines. By the end of the machine demonstration, almost every farmer has understood the function of each machine. The knowledge of farmers about making animal feed from corn cobs has increased to very knowledgeable. With the existence of multifunctional machines, it is hoped that farmers will not depend on traders and can increase their income from their corn products. The profits that farmers get are expected to be used as capital to fulfill production inputs for corn cultivation. Machine technology brings changes in farmers' activities and social changes by changing lives from an economic perspective, making it easier for farmers to peel and break corn

Full textAbstract:
The results of the analysis of long-term trends in changes in individual climatic characteristics and variations in weather conditions of the growing season in the forest-meadow zone of the Middle Urals for the period from 1958 to 2020 are presented, their influence on the choice of hybrids and some elements of corn cultivation technology are estimated. As a result of calculating the linear trend, a statistically proven trend has been established to increase the sum of active temperatures above 10 °C for May – September. At the same time, random fluctuations of the analyzed parameters over the years have a direct impact on corn development and productivity, and the limiting factor is the lower limit of these fluctuations, the values of which increase throughout the analyzed period. Nevertheless, the variation over the years remains strong, and the lower limit of these fluctuations does not reach the minimum level for the stable maturation of early-maturing corn hybrids. Therefore, for the conditions of the Middle Urals, the previous recommendations concerning the selection of corn hybrids for early maturity, cold resistance and drought resistance remain relevant. At the same time, the revealed climatic trend allows to predict an increase in the probability of obtaining feed with a high content of exchange energy, which characterizes it as positive one.

Abstract Corn is vital crop cultivation in Gorontalo Province and becomes major export comodity from the agricultural sector. Most of corn farms are located in hilly and mountainous area known as sloping agriculture. The main aim of this study was to analyze the advantages of portable combine machine, peeling-thresher corn as appropriate technology, to support sloping agriculture, reduce cost production, and generate farmers income. This research was conducted in Tutuwoto village that involves two farmers group association (POKTAN) namely POKTAN Dusun Beringin and POKTAN Dusun Puncak. The POKTAN members stated that labour budget is the most expensive for corn production in their region. Dissemination of peeling-thresher machine is proven shorten of harvest and post-harvest steps in the current pattern. Results revealed that the technological input decreased 34.50% operational cost of harvest and post-harvest from Rp8,520,000 to Rp2,940,000. Furthermore, its application improved the farmers net profit 51.67% ha−1 and 85.01% ha−1 for own and loan capital respectively, in one growing season about 4 month. It is concluded that the proper equipment implemented in hilly farming reduces cost production and its implication redoubles revenue of the corn farmers.
