Abstract (English):
In the period from 2021 to 2023, in the conditions of radioactively contaminated sod-podzolic sandy soils of the Novozybkovsky district of the Bryansk region, studies were carried out on the possibility of managing the yield of buckwheat agrocenosis by using chemicalization tools to analyze environmental stability and plasticity parameters using the "yield" criterion. Assessment of the adaptive properties of buckwheat agrocenosis in the control variant revealed that the culture gives stable grain yields, while the agricultural system is stress-resistant to changes in climatic conditions. An analysis of the yield potential of buckwheat agrocenosis at different levels of use of chemicalization agents established: 1) the environmental conditions index varied from - 1.35 to 0.88 depending on the year of the study; 2) the highest coefficient of adaptation (1.36) to changing environmental conditions was detected at the highest level of the use of chemical agents; 3) without the use of chemizing agents, buckwheat agrocenosis in extreme conditions reduces productivity to the least extent, the use of mineral fertilizer and biological product leads to a decrease in stress resistance; 4) the most stable yield of buckwheat agrocenoses is characteristic under the conditions of N60P60K60 use; 5) agrocenosis is most responsive to changes in environmental conditions when using N60P60K120 + Albite; 6) the highest responsiveness to changing environmental conditions in combination with the low stability of the buckwheat agrocenosis crop is typical for the option of using mineral fertilizer in the normal N60P60K120, both separately and together with the Albit biological product. When using chemicalization tools, it is possible to control the yield potential of buckwheat in the conditions of sod-podzolic sandy soils of the south-west of the Bryansk region, even under contrasting environmental conditions.
