The results of the 2024 research confirm the feasibility of introducing five-field crop rotations with a 40% saturation of the arable land structure with grain and row crops. Among the predecessors in the first field (20% of the structure), it is worth alternating soybeans and corn with periodic use of fallow. The study of various agrophones revealed their ability to increase the resistance of agrophytocenoses to adverse environmental conditions, in particular, under conditions of abnormal drought, high temperatures and insufficient humidity. It has been found that in field crop rotations, a differentiated resource-saving system of tillage should be used on the basis of deep (up to 33-35 cm) moldboardless loosening for row crops and discing tillage for grain crops, as well as periodic ploughing once per rotation of a five-field crop rotation, primarily when growing corn. Studies have shown that such a system helps to stabilise and increase the productivity of agrophytocenoses by 10-15% by optimising the soil water regime and reducing the negative impact of biotic and abiotic stress factors. Improved agrotechnological methods that reduce the natural stress load on plants, increase seed germination, germination and growth intensity during the early growing season. The physiological and biochemical mechanisms of inducing seed germination, which simultaneously contribute to the adaptation of seedlings to adverse environmental conditions: lack of humidity, low or high temperatures, increased agrochemical load in agrophytocenoses, are investigated.
