Biological features and productivity of soybean varieties grown in the unstable moisture zone on leached chernozem

Abstract

Abstract The article presents the results of studies on the biological characteristics and productivity of new promising varieties of different ripeness groups, Armavir experimental station selection - a branch of the Federal state budgetary scientific institution “Federal scientific center “V.S. Pustovoit All-Russian Research Institute of Oil crops”. The studies were carried out in an unstable moisture zone on the basis of the experimental station of the Stavropol State Agrarian University; the soils of the experimental plot are leached chernozem. On average, over three years of research, it was found that the highest yield in the group of quickly ripening varieties was obtained by Parus variety - 1.73 t/ha, which was 0.43 t/ha more than the standard Bara variety. In the group of early ripening varieties, the highest yield was obtained by the standard Duar variety - 1.58 t/ha. The mid-ripening Zara variety showed a maximum yield of 1.84 t/ha among the studied varieties, exceeding the standard Vilana variety by 0.19 t/ha. The highest protein content in soybean grain was noted in the Vilana variety - 43.2%, and the vegetable oil in the Vestochka variety -24%.
