he main goal of the study is to optimize the ratio of high potential productivity of winter wheat, environmental sustainability and environmental improvement functions at the level of the variety, agrocenosis, agroecosystem and agrolandscape. Research has been conducted since 2017 in a field experiment organized on the basis of an adaptive landscape approach. It was deployed on the plakor and slope of the southern exposure in parts 1-3° and 3-5°. The object of the research – varieties ‘Veselka’, ‘Synthetics’, and ‘Ariadna’ created in the Laboratory of breeding and seed production of winter wheat of Belgorod Federal Agricultural Research Center of the Russian Academy of Sciences. The ‘Almera’ variety was taken as the standard. The soil cover is represented by typical Chernozem. To improve the productivity of agricultural crops in conditions of slope agrolandscapes, it is advisable to choose and place the variety according to the selected microzone. It is necessary to cultivate the varieties at the specific plots of arable land with the most optimal parameters for the complex orographic, climatic and edaphic conditions for this variety, and in which plants will be able to give the highest yield. Thus, in plakor, it is advisable to give preference to cultivating ‘Ariadna’ and ‘Veselka’ varieties (6.2-6.3 t/ha). For slope microzones, the ‘Synthetics’ variety (4.4-5.3 t/ha) is well suited. The presented set of varieties gave stable yield in difficult conditions of erosive agricultural landscapes, thus can be considered as an innovative development in crop production.
