“…Corn yields in Ukraine almost doubled from 2000 to 2021 -from 27 cwt/ha (2000) to 50 cwt/ha (2021). The maximum yield of corn in individual agricultural enterprises located in the Forest-Steppe zone, under the conditions of production intensification, reached 170-180 cwt/ha (Tkachuk & Bondarenko, 2022).…”

Ukraine has a developed agricultural sector of the economy, where agriculture accounts for 10.4% of the gross domestic product. The relevance of the subject is due to the fact that agricultural production, which is of strategic importance for the country, is very sensitive to ongoing climate changes. Therewith, the crop industry is already undergoing a process of adaptation to the consequences of climate change and agrometeorological factors, which is manifested in the expansion of the range of cultivated crops. The purpose of this study was to predict the adaptability of heat-loving agricultural crops by their yield in various natural and climatic zones of Ukraine. In the course of the research, such methods as analysis, synthesis, factor analysis, correlationregression, and mathematical-statistical were used. Based on the results of the conducted studies, the expediency of considering climate change to obtain high yields of both conventional agricultural crops and heat-loving ones, which were not typical for Polissia and Forest-Steppe, is proved. Based on the analysis of the dynamics of crop yields, it is identified that it is advisable to reorient agricultural production to the cultivation of heat-loving crops – corn, sunflower, soy, and rapeseed in the Forest-Steppe, which in recent years give the same or slightly higher yields than in the south of Ukraine. Growing these crops in the Polissia zone is unprofitable – the yield is quite low, so in these regions, it is worth continuing to grow conventional crops (cereals, legumes, vegetables, potatoes). The established dependences of crop yields on climatic and agrometeorological factors allowed identifying a complex of factors that play a major role in the formation of the yield of specific crops. The developed crop yield models based on multiple correlation allow for predicting it. The results of the study can be useful in planning and optimising the activities of agricultural enterprises, and agriculture in general, in various natural and climatic zones of Ukraine, as a strategic branch of the economy

Purpose. To determine the economic and energy assessment of forage crop rotations including forage grain crops under different fertilization systems and to establish the most effective variants for the zone of unstable moisture on the Left-Bank Forest-Steppe of Ukraine black soils. Methods. Field studies were conducted during 2021-2023 at different variants long-term crop rotations with systematic placement in triplicate. Methods of field and laboratory research in feed production, statistical analysis were used. Results. High-yielding crop rotations including grain crops provided grain productivity from 4.08 to 5.77 t/ha per 1 ha of crop rotation area, and feed units – from 8.70 to 10.47 t/ha. The cost price of grain was 3359-3724 UAH/t, feed unit – 1859-1876 UAH/t, profitability – 122.5-151.1%. The saturation of crop rotations with high-energy crops contributed to the accumulation of energy in the yield up to 698392 MJ/ha, the energy efficiency coefficient (EEC) was 5.4-7.02, which is significantly higher than in the variant with a smaller share of corn (EEC – 3.8). With a corn yield of 10.0 t/ha, the energy accumulation was 150608 MJ/ha, EEС – 8.76, while with a yield of 8.5 t/ha – 129349 MJ/ha, EEС – 7.6. Conclusions. The high efficiency of forage crop rotations on the Left-Bank Forest-Steppe of Ukraine black soils is the result of the optimal selection of crops in the crop rotation. For dairy farms, it is recommended to use high-energy crops such as corn for grain and silage. For pork farms, optimal crops include corn for grain, barley, peas and soybeans. Such crop rotations provide high yields of grain, feed units and energy, as well as high profitability.
