The influence of agricultural methods and soil and climatic conditions on soybean cultivation in the southern regions of the Amur Region was researched. Schemes of two-factor experiments to study the effectiveness of deepening the arable layer of soil during crop cultivation in 2014–2016 included the following options. Factor A – tillage: autumn – disk plowing or cultivation; spring disk plowing or cultivation; summer – inter-row cultivation with or without para-plowing. The options were combined in different ways, whereby the option of soil tillage with a disc harrow in autumn and spring was taken as control. Factor B: sowing with seeders SZ-5.4 and SP-3.6 L with row spacing (options – 15, 45 and 60 cm) with various tillage systems. In 2017–2018 experiments were carried out according to the following schemes. Factor A – tillage: in autumn tillage depth at 0.12 m with a disc harrower PM-8; in spring, before sowing – at 0.10 m (cultivator Case Tiger Mate 225 – control); autumn – tillage depth at 0.28 m (cultivator Lemken Karat 9/400); spring, before sowing – at 0.10 m (Case Tiger Mate 225). Factor B – seeding units included Amazon DMC 9000 (control); Amazon DMC 1200, Case Pro Disk 500 AFS, John Deer 1890, Lemken Solitair 12, Horsch Pronto 9 DC, Tom’ 12, SP-3.6 L. Deep autumn cultivation, in contrast with disk plowing, ensures a more favorable waterair regime for plants and an increase in soybean yield. Seeding units Case Pro Disk 500 AFS, John Deer 1890, Amazon DMC 9000 and SP-3.6 L used in combination with Lemken Karat 9/400 + Case Tiger Mate 255 machines for deepening the arable layer provided an increase in soybean yield by 25.0–38.3% compared to soil tillage with discs. It is recommended to use wide-span seeding units for soybean cultivation in large and medium-sized farms in fields with subdued relief in accordance with high-intensity technology. It is advisable to use SP-3.6 L seeder with a seed shoe for organic crop production in small-scale agricultural enterprises.

Introduction. The importance of specialization research is due to its role in the economic growth of the country, as it contributes to the resources concentration on the production of competitive products, the provision of scientific and techno-logical development and increase the efficiency of agricultural enterprises. The purpose of the study is to develop mechanisms for managing commodity specialization of agricultural enter-prises. Results. The unique features of agriculture in the general structure of the national economy are identified. The deci-sive role of land resources has been determined. The influence levels on the management of commodity specialization of agri-cultural enterprises are broadened: nationwide, regional and local, for which the means of influence are allocated. The rea-sons for the imbalance in the structure of agricultural production are considered. The groups of factors that influence the resources reproduction as factors of agricultural production are distinguished: socio-political, socio-economic, priorities of state agrarian policy, using level of agricultural land and other resources, natural and climatic conditions, seasonality of production, energy and resource intensity, innovative technologies implementation. The structure of Ukrainian agriculture on 3 levels in terms of crop, livestock and hunting is offered. The necessity factors of systematic influence on commodity specialization management of agrarian enterprises are determined. The determinants of commodity specialization of agricul-tural enterprises are presented. Conclusions. The architecture of the organizational and economic mechanism for managing the commodity speciali-zation of agricultural enterprises is provided, which includes the internal environment of the enterprise, the direct mecha-nism, options for development, the conditions influence of the external environment functioning and the factors of influence on the specialization of the agricultural enterprise. The concept takes into account tendencies of economic potential for-mation, internal infrastructure of the enterprise, basic architectural decisions and standards, management model and re-quirements to management processes, and also defines principles of transition from the existing state of the enterprise to the target one. Keywords: commodity specialization, agricultural enterprises, structure of agriculture, determinants, organizational and economic mechanism, crop production, livestock.

Introduction. The active movement of Ukraine towards integration into the world economy, the liberalization of customs regimes, the expansion of sales markets and the introduction of innovations have created new prospects for the progress of the production of exports-oriented agricultural products. Foreign economic activity plays a significant role in the economy of the country, affects its internal dynamics and competitiveness, so the research of trends in the formation of commodity exports are of current importance.  Aim and tasks. The aim of the article is to research the dynamics of progress and the current state of the agricultural sector of the economy of Ukraine in the field of crop production, the contribution to it of the main categories of farms and the role of the agricultural sector in the formation of the exports potential of the country. For the solvation of this problem, a number of statistical materials, scientific publications and Internet resources on the indicators of production activities of agricultural enterprises were used, the methods of mathematical statistics and economic and mathematical modeling were applied. Results. The conducted researches allowed to evaluate the contribution of the main categories of farms to crop production in 2010-2017. To estimate the distribution of land between agricultural enterprises the Lorenz curve was constructed, the Gini coefficient and the Hoover index were calculated. Calculations showed that 81.5% of enterprises had 13.4% of the total land area,  and in order to achieve an equal distribution of land between enterprises, it is necessary to redistribute 68% of the land areas. It has been established that in the agricultural sector of Ukraine there is a polarization in the production of agricultural products – small-scale forms of management dominate in the production of labor-intensive and low-income goods, while products of powerful agricultural enterprises have a high yield and low labor intensity. One of the leading places in crop production is the cultivation of sunflower due to its high profitability. Linear and multiplicative regression models of dependence of the volume of sunflower production. It was determined that high levels in the structure of commodity exports of Ukraine belong to sunflower oil, wheat, corn, barley, rapeseed and soybeans, and it was noted the important role of agricultural holdings in forming the exports potential. Conclusions. Agricultural enterprises, in particular, holdings, which have more opportunities than households for increasing their production through the introduction of innovations and the scale of production play a growing role in the production of agricultural products . Ukraine makes a significant contribution to global food security, but its position in the world markets as a producer and supplier of raw materials is fixed. Exports of goods with a low level of added value largely depend on fluctuations in world prices, which contributes to the sensitivity of the domestic economy to external negative trends, therefore, Ukrainian commodity exports need to diversify and increase the share of high technological value added goods.

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels. Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied. Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm. The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

The regional agroecological conditions, specific to the Transylvanian Plain, are favorable to soybean crops, but microclimate changes related to global warming have imposed the need for agrotechnical adaptive measures in order to maintain the level of soybean yield. In this study, we consider the effect of two soil tillage systems, the seeding rate, as well as the fertilizer dosage and time of application on the yield and quality of soybean crops. A multifactorial experiment was carried out through the A × B × C × D − R: 3 × 2 × 3 × 3 − 2 formula, where A represents the year (a1, 2017; a2, 2018; and a3, 2019); B represents the soil tillage system (b1, conventional tillage with mouldboard plough; b2, reduced tillage with chisel cultivator); C represents the fertilizer variants (c1, unfertilized; c2, one single rate of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus; and c3, two rates of fertilization: 40 kg ha−1 of nitrogen + 40 kg ha−1 of phosphorus (at sowing) + 46 kg ha−1 of nitrogen at V3 stage); D represents the seeding rate (1 = 45 germinating grains (gg) m−2; d2 = 55 gg m−2; and d3 = 65 gg m−2); and R represents the replicates (r1 = the first and r2 = the second). Tillage had no effect, the climate specific of the years and fertilization affected the yield and the quality parameters. Regarding the soybean yield, it reacted favorably to a higher seeding rate (55–65 gg m−2) and two rates of fertilization. The qualitative characteristics of soybeans are affected by the fertilization rates applied to the crop, which influence the protein and fiber content in the soybean grains. Higher values of protein content were recorded with a reduced tillage system, i.e., 38.90 g kg−1 DM in the variant with one single rate of fertilization at a seeding rate of 45 gg per m−2 and 38.72 g kg−1 DM in the variant with two fertilizations at a seeding rate of 65 gg m−2.

In the past decade, to improve crop production and productivity, Ethiopia has embarked on an ambitious irrigation farming expansion program and has introduced new large- and small-scale irrigation initiatives. However, in Ethiopia, poverty remains a challenge, and crop productivity per unit area of land is very low. Literature on the technical efficiency (TE) of large-scale and small-scale irrigation user farmers as compared to the non-user farmers in Ethiopia is also limited. Investigating smallholder farmers’ TE level and its principal determinants is very important to increase crop production and productivity and to improve smallholder farmers’ livelihood and food security. Using 1026 household-level cross-section data, this study adopts a technology flexible stochastic frontier approach to examine agricultural TE of large-scale irrigation users, small-scale irrigation users and non-user farmers in Ethiopia. The results indicate that, due to poor extension services and old-style agronomic practices, the mean TE of farmers is very low (44.33%), implying that there is a wider room for increasing crop production in the study areas through increasing the TE of smallholder farmers without additional investment in novel agricultural technologies. Results also show that large-scale irrigation user farmers (21.05%) are less technically efficient than small-scale irrigation user farmers (60.29%). However, improving irrigation infrastructure shifts the frontier up and has a positive impact on smallholder farmers’ output.

Adoption of cover crop interseeding in the northwestern Corn Belt in the USA is limited due to inadequate fall moisture for establishment, short growing season, additional costs, and need for adapted winter-hardy species. This study evaluated three cover crop treatments—no cover crop, winter rye (Secale cereale L.), and winter camelina (Camelina sativa (L.) Crantz)—which were interseeded at the R6 soybean growth stage, using two different soybean (Glycine max (L.) Merr.) maturity groups (0.5 vs. 0.9) and two row spacings (30.5 vs. 61 cm). The objective was to evaluate these treatments on cover crop biomass, soil cover, plant density, and soybean yield. Spring wheat (Triticum aestivum L.) grain yield was also measured the following year. The early-maturing soybean cultivar (0.5 maturity) resulted in increased cover crop biomass and soil cover, with winter rye outperforming winter camelina. However, the early-maturing soybean yielded 2308 kg·ha−1, significantly less compared with the later maturing cultivar (2445 kg·ha−1). Narrow row spacing had higher soybean yield, but row spacing did not affect cover crop growth. Spring wheat should not follow winter rye if rye is terminated right before seeding the wheat. However, wheat planted after winter camelina was no different than when no cover crop was interseeded in soybean. Interseeding cover crops into established soybean is possible, however, cover crop biomass accumulation and soil cover are limited.

Abstract Three row spacings and two planting dates for peanuts, Arachis hypogaea L., were examined in 1993 and 1994 to determine the influence of the canopy environment on lesser cornstalk borer, Elasmopalpus lignosellus (Zeller) (Lepidoptera: Pyralidae), other arthropods, and alflatoxigenic fungi. Climatically, 1993 and 1994 were disparate years. Decreasing row spacing increased relative leaf area and light interception by the canopy but, compared to difference between planting dates or years, had a relatively small impact on soil temperatures and relative humidity within the canopy. Late planting produced smaller plants, retarded canopy development, and reduced yield in both years, but especially in 1993 when it was hot and dry. The wide row spacing did not yield as well as twin and normal row spacings in either year. Lesser cornstalk borer damage and aflatoxin concentration were higher in the late planting than in the early planting of 1993, but were unaffected by row spacing. Fewer predatory arthropods were caught as row spacing decreased in both beat and pitfall samples, but planting date had variable effects. Prevailing climatic conditions and planting date appeared to be more important in influencing the canopy environment and pest densities than was row spacing.

Water scarcity is rising as a global issue, because the planet earth is facing a global water crisis, which is considered something that can destroy environmental sustainability of our planet. The fact is that humanity’s demand is depleting natural resources faster than nature can replenish itself; if human habits and unsustainable use of water resources do not change, water scarcity will inevitably intensify and become a major cause of conflict among different nations of the world. The water scarcity issue is a crucial issue but unfortunately it has not received due attention in past. Pakistan, which once was a water abundant country, now facing a situation of water scarcity. Pakistan has a poor irrigation system which results 60% loss of its water; Pakistan uses more water for crop production than other countries. Likewise, the country harvests water from rainfall, rivers, snow, and glaciers. The country is facing a serious water crisis that is caused by different factors, such as changing climatic conditions, rising population, poor irrigation system, poor political will, and rapid urbanization. The water crisis of Pakistan is expected to worsen in coming years. This is a drastic situation which calls for emergency measures. With this background, the present study provides a detailed view of the water situation in the country with challenges to water management. The study also suggests some recommendations for policymakers to improve the water crisis situation in the future.

On-farm compound feed production from self-produced raw materials is favorable to agricultural enterprises under present-day conditions. The authors carried out a comparative technical and economic study of the conventional and modular small-scale on-farm compound feed plants with a capacity of 2 tons per hour, designed for agricultural enterprises with an average livestock population of 6…8 thousand pigs. The proposed modular plant consists of two modules – the operative storage of raw materials and the main module of grinding and mixing. Modules with installed equipment are delivered and placed on a light foundation, connected by transport equipment and with tanks for raw materials and fi nished products. The conventional factory is a technological line housed in a hangar and used for crushing, metering, and mixing raw materials. It consists of a separator, a hammer mill, weighing equipment, a mixer, containers for raw materials and fi nished products, transport, and aspiration equipment. The technical and economic analysis has shown that the erection and operation of the on-farm modular enterprise require 41% less capital investments than a traditional compound feed plant of the same capacity. The use of a small-scale modular plant will reduce operating costs by 23.8% (from 3094 to 2358 thousand rubles), increase the specifi c economic eff ect from the compound feed production by 1.6% (from 8.64 to 8.78 thousand rubles per ton) and return on margin by 4% (from 10.2 to 10.6%), reduce the payback period by 42% (from 0.8 to 0.46 years), and increase the net present value by 3% (from 66167 to 68216 thousand rubles), as compared to a conventional enterprise. The modular on-farm plants producing loose compound feed with a productivity of up to 3 tons per hour are profi table and economically sound as they can increase production effi ciency of compound feeds for farm animals.`
