Introduction. An increase in crop production from the growing area of both vegetable root crops and all agricultural products results in grows of the load on the machine-technology complex when harvesting. The reason is that in the structure of machine-technological complexes there are not devices providing the qualitative screening of the heap incoming for processing. The purpose of the study is to identify the areas with the minimum value of soil screening on the rod elevator surface depending on the elevator apron angle and to develop recommendations and proposals for improving the separation quality. Materials and Methods. The article describes the methodology and results of laboratory studies of rod elevators with an asymmetric arrangement of web agitators and an adjustable elevator apron angle to determine the soil screening quality on its surface. We used the method of comprehensive assessment of the quality and stability of technological operations based on quantitative optimization criteria. Results. The highest value of the screened soil weight is at the wavelength attenuation section of the rod elevator working branch 1,020 mm cause by action of the elliptical web agitator at an elevation angle of 5 gon. Discussion and Conclusion. The rod elevator with asymmetric arrangement of web agitators and adjustable elevator apron angle increases the soil screening quality along the entire length of the elevator apron by 10 %, and therefore increases the completeness of separation of root crops from soil impurities.

Abstract The chemical control of pests and weeds is employed to improve crop production and the quality of agricultural products. The intensive use of pesticides, however, may cause environmental contamination, thus altering microbial communities. Cryptococcus gattii is an environmental yeast and the causative agent of cryptococcosis in both humans and animals. Up to this day, the effects of agrochemicals on human pathogens living in nature are still widely unknown. In this work, we analyzed the susceptibility of C. gattii to nonfungicide agrochemicals (herbicides and insecticides). Microdilution and drug-combination susceptibility tests were performed for the herbicides flumioxazin (FLX), glyphosate (GLY), isoxaflutole (ISO), pendimethalin (PEND), and also for the insecticide fipronil (FIP). Moreover, these compounds were combined with the clinical antifungals amphotericin B and fluconazole. The MIC values found for the agrochemicals were the following: &lt; 16 μg/ml, for flumioxazin; 128 to 256 μg/ml, for FIP, ISO, and PEND; and &gt;256 μg/ml, for GLY. Synergistic and antagonistic interactions, depending on the strain and concentration tested, were also observed. All strains had undergone adaptation to increasing levels of agrochemicals, in order to select the less susceptible subpopulations. During this process, one C. gattii strain (196 L/03) tolerated high concentrations (50 to 900 μg/ml) of all pesticides assessed. Subsequently, the strain adapted to flumioxazin, isoxaflutole and pendimethalin showed a reduction in the susceptibility to agrochemicals and clinical antifungals, suggesting the occurrence of cross-resistance. Our data point to the risk of exposing C. gattii to agrochemicals existing in the environment, once it might impact the susceptibility of clinical antifungals.

This article presents the results of the analysis of the current state of crop production in Russia, as well as the dynamics of the main indicators of the industry. Crop production occupies a position of primary importance in the agro-industrial complex of the country, since the cost of agricultural products in actual prices amounted to 5348.8 billion rubles in 2018 (according to preliminary data of 2019 – 5907.9 billion rubles), including crop production – 2756.1 billion rubles (3160.0 billion rubles – in 2019) or 51.5% (53.5% in 2019); the index of crop production – 98.5% (in 2019 – 106.1%). The gross grain harvest in 2018 amounted to 113.3 million tons; in the structure of grain production, the largest share belongs to wheat – 63.69% or 72.1 million tons, then barley – 15.00% (16.99 million tons), corn – 10.08% (11.4 million tons), oats – 4.17% (4.7 million tons), rye – 1.69% (1.9 million tons), rice – 0.92% (1.0 million tons), buckwheat – 0.82% (0.9 million tons) and other crops – 7.79% (8.8 million tons). The most favorable situation was with such technical crops as soy and rapeseed. In 2018, record harvests of soybeans and rapeseed were collected – 4026.8 and 1988.7 thousand tons, respectively. The volume of vegetable production in all categories of farms for the period 2014-2018 increased from 12821.02 to 13685.23 thousand tons; the yield and marketability of products also increased. The number of vegetables and melons per population was 76.18 % in 2018.

Ecological Footprint Analysis

This paper employs the ecological footprint analysis method to analyze the ecological footprint of the import and export trade of major agricultural products during the years of 1990-2009 in China. The results indicate that the footprint of the main agricultural products’ import and export of China presents obvious two-stage characteristics: during the years of 1991-2001, the import and export trade as a whole tended to be stable with ecological deficit; however, during the years of 2001-2009 the import trade increased significantly. The export trade tended to be stable. There was ecological surplus in successive years. In order to promote the sustainable development of China’s major agricultural products, we should optimize the industrial structure of the major agricultural products, implement the technical improvement of crops, ameliorate the ecological environment of crop production, and promote the development strategy of agricultural trade.

The digitalization of agriculture is connected with the increase in the efficiency and sustainability of its functioning. The paper studies the dynamics of indicators of the development of agricultural production in the Samara region. First of all, agriculture of the region is represented by crop production, the share of which in the total volume for a number of years has been over 60%. The basis of the regional crop production is the production of high quality food grains. Cereals are one of the most demanded items in the export of agricultural products. For the period from 2009 to 2020 the gross harvest of grain crops increased 1.6 times. The Samara region is one of the ten regions of the Russian Federation in terms of sunflower production. The gross harvest of sunflower, which serves as a raw material for the main export position of the region namely sunflower oil, has increased fivefold over the period. Digital technologies, the need to use which is determined by general trends in the development of the world economy, create new opportunities to increase the competitiveness of products and further develop the export potential not only of a particular region, but also of the country as a whole.

Ensuring food security is achieved by increasing the volume of agricultural products in compliance with environmental requirements. The proposed technologies for pre-sowing treatment of rapeseed seeds with EMF UHF will improve the quality of these seeds, which, ultimately, will affect the increase in yield, as well as provide gain in yield and improve the quality of oil during processing. The implementation of the project of pre-sowing treatment of rapeseed seeds with EMF UHF in this regard, for example, in LLC “Nichkinskoe” of the Minusinsky District, seems promising. The article devoted to the economic assessment of two possible technologies for pre-sowing treatment of seeds with EMF UHF in LLC “Nich-kinskoe” of the Minusinsky District with the use of spring rapeseed varieties “Nadezhny-92” and “Hephaestus”. It is established that additional income can be obtained for both options.

Pakistan is an agriculture-based country, so the agricultural sector is known as the backbone of the national economy. Considering the national economy and the agricultural industry, it is necessary to focus on earnings through agricultural products export to improve the livelihood of local farmers. Therefore, the current study aimed to analyse the short-term and long-term factors affecting agricultural products export. The annual time series of 1976–2016 were collected from World Bank indicators, the Food and Agriculture Organization, and the Statistical Bureau of Pakistan. An autoregressive distributed lag, along with a vector error correction model, was employed. A cointegration test showed long-term associations between the selected variables. While the autoregressive distributed lag model confirmed the short-term correlation between area sown and crop production towards agricultural products export, there is no long-term relationship between the selected variables. In addition, the bidirectional correlation between employment in agriculture and agricultural products export was confirmed by the vector error correction model. Therefore, it is essential to increase agricultural production with the available natural resources to increase foreign earnings.
