The purpose of this study was to evaluate the effectiveness of the crop rotations under study for grain yield in different yearsbased on weather conditions. The highest productivity among all the schemes of the crop rotations was obtained in five-courseand four-course ones with the inclusion of leguminous and late crops, where the yield of grain from 1 hectare of arable landamounted to 1.70-1.81 tons with the average productivity of all crop rotations amounting to 1.54 tons. Based on the researchresults, the study establishes that in order to achieve optimal efficiency of agroecocenoses in conditions of insufficient moisture,it is necessary to include late crops, such as corn and grain sorghum, which are able to produce stable yields in different years,in the structure of sown areas. It is also advisable to include leguminous crops in the structure of sown areas, which increase theefficiency of crop rotations and contribute to the preservation of soil fertility.
