“…Environmental change has a complex impact on crop yields, with favorable climatic conditions being a cornerstone for achieving high agricultural performance [1][2][3]. According to prospective assessments, climatic conditions will be favorable for agricultural production until the mid-21st century, but these conditions will start to deteriorate towards the end of the century [4][5][6].…”

This study analyzes the impact of climatic conditions on the development of grain and leguminous crops in the Trans-Baikal region. Insufficient precipitation, droughts, early frosts, and a short growing season limit the choice of crops suitable for cultivation in the region. Grain crops, which occupy the largest share of sown areas, are chosen as the object of research. Based on theoretical and economic analysis and data on sown areas, yield, average temperature, and precipitation during the growing season, a regression model has been constructed to assess the impact of climatic factors on the gross grain harvest in the Trans-Baikal region.

The influence of the probiotic product Amylocin in the diet of laying hens on the biogas production potential of their droppings has been studied. A laboratory batch experiment on litter anaerobic fermentation was carried out. The total and specific biogas and methane yields from poultry droppings in the control and experimental groups were determined. It was found that the use of the probiotic Amylocin in the diet of laying hens reduced the biogas productivity of their dung; the average specific biogas and methane yields from the droppings of hens that received the probiotic was 73.90 and 19.52 ml/g of organic matter, respectively; the corresponding values for hens the diet of which did not contain Amylocin was 120.97 and 46.69 ml/g of organic matter, respectively. At the same time, the litter of the poultry group with the highest productivity was characterized by the lowest yield of biogas and methane (51.56 and 14.05 ml/g organic material, respectively), which may be due to the better conversion of feed nutrients in the poultry body, as well as to the inhibitory effect of probiotic microflora on the methane-forming consortium in the droppings. The methane concentration in the biogas from poultry litter averaged 29.75% in the experimental groups and 38.60% in the control. Only biogas from droppings of poultry that received the lowest dose of the additive contained 46.71% methane and was combustible. The addition of carbon-rich co-substrates can potentially increase the efficiency of converting into biogas of droppings of laying hens fed with Amylocin. biogas, methane, poultry litter, laying hens, Amylocin, Bacillus subtilis, Bacillus amyloliquefaciens The work was funded by the Russian Foundation for Basic Research, project no. 18-47-310008 р_а.

Study of the effectiveness of the use of increasing doses of mineral fertilizers (N16P16K16...N120P120K120) was carried out in 2020-2022 in the conditions of the Ryazan region on dark gray forest heavy loamy soil of average fertility. The object of the research was a new variety of spring barley Raphael, included into the State Register of the Russian Federation for the Central (3) and Volga–Vyatka (4) Regions in 2022 (patent No. 12254). As the result of the research, there was revealed a positive trend for raising the yield of the Raphael variety resulted from the use of increasing doses of NPK (y = 0.1829x + 6.36, R2 = 0.8866). On average, over the years of the research, the minimum yield productivity (6.50 t/ha) was shown by the control variant (N16P16K16), the variant with application of high doses (N120P120K120) had the maximum productivity (7.40 t/ha). The yield increase by 0.6...0.9 t/ha was provided by mineral fertilizers in doses of N45P45K45...N120P120K120. The yield of barley per year with sufficient moisture supply during the growing season (HTC = 1.39) was 4.6-5.1 % higher than in dry years (HTC = 0.63-0.53). Structural analysis of yield indicates that during the experiment, the yield of this variety has been influenced by the length of the ear (r = 0.689), the number of grains in the ear (r = 0.467), the weight of grain per the ear (r = 0.715). Increasing doses of applied fertilizers led to an increase in the leaf surface area of plants and the height of the productive stems. The highest protein content in barley grain was observed in the variant with the use of N120P120K120 (on average 14.1 %), the minimum – with the application of N16P16K16 (on average 13.2 %). The calculation of economic efficiency showed that the highest conditional net income (69413 rubles/ha) and the level of profitability (187.1 %) with the yield of the new Raphael variety of 7.1 t/ha can be achieved by applying medium doses of fertilizers N45P45K45.
