In the conditions of the west of the Bryansk region, on sod-podzolic soils of light grain size distribution, the adaptive properties of buckwheat were assessed depending on fertilizer systems in terms of environmental stability and plasticity according to the "yield" criterion. Changes in the yield of buckwheat grains were analyzed in the period from 2020 to 2022, which differed in weather conditions. As a result of the study, it was found that the use of mineral fertilizer and Albit increases the adaptation of the culture to environmental conditions, while the ratio of nutrients in it plays a role. The environment of the west of the Bryansk region during the research period creates insignificant variability in buckwheat yield, the use of Albit biologics and phosphate- potassium fertilizer makes variability average. The greatest stress resistance, the minimum value of the yield range under contrast conditions was revealed on the option without the use of fertilizer, and the greatest crop stability under experimental conditions was observed when using mineral fertilizer in a dose of N60P60K120. The use of mineral fertilizer enhances stability and reduces the responsiveness of crops to environmental changes
