Create a balanced crop rotation model based on the latest means of production and technologies that ensure the consolidation of high productivity and compliance with agri-environmental standards, efficient use of material resources and preservation of agro-landscapes. Investigate the adjustment of crop rotation value of individual crops, the growth of the structural concentration of the most commercially viable crops, the transition mainly to organic fertilizers of plant origin, optimization of the location of mineral fertilizers in the soil against the background of shelf-free methods of basic tillage, determination of the dynamics of weed infestation, determination of the dynamics of weed infestation in crop rotation. popup.description2 The purpose of the work is to substantiate the optimization of agrobiological regimes for increasing productivity and forming the ecological and economic balance of zonal multi-rotational crop rotations under different farming systems and anti-erosion methods of soil cultivation. The object of the study is the processes of changes in agrobiological parameters of the formation of crop rotation crop yields, the efficiency of field crop rotations; soil fertility: indicators of agrophysical and agrochemical properties, water regime; crop yields; productivity of 5-8-field field crop rotations; economic efficiency of growing crop rotation crops; resource conservation. The parameters of the ecological and economic balance in crop rotations under different farming systems are obtained. The results of research on the optimization of agrobiological regimes for increasing crop rotation productivity based on anti-erosion methods of soil cultivation are summarized. Predecessors and fertilizers affected the yield of winter wheat: after black rye, grain yield was 5.25 t/ha, after occupied, sideral rye and peas - 3.21-3.86 t/ha, after alfalfa - 2.19 t/ha. More effective are the organo-mineral and mineral fertilization systems, developed taking into account agrochemical soil diagnostics. In 8-field crop rotations, the highest productivity indicators (for 2021-2025) were in 2023. The grain yield in the grain-steam-tillage crop rotation was 3.38-3.56 t/ha, in the grain-tillage 2.94 and 3.12; in the grain-grass-tillage - 2.40 and 2.60 t/ha. Grain yield in grain-grass-till crop rotation is 4.79 and 5.20 t/ha, (there are no peas and soybeans in it); in grain-steam-till crop rotation – by 6.2 and 9.7%, and in grain-till crop rotation – by 15.1 and 13.9% less.
