The influence of various fertilizer systems on the yield of soy beans and wheat in the crop rotation of the long-term agrochemical stationary of A.K.

The article presents the results of the study of various fertilizer systems in a long-term stationary experiment conducted in 2018–2020, their influence on the change in soil fertility, yield and quality of seeds of the Primorsky Krai crop rotation. During the wheat growing the variant with a complex fertilizer system and a double NPK rate stood out, which provided the greatest increase in yield and obtaining grain with a sufficiently high protein and gluten content. The maximum yield of soybeans, high protein content in seeds (39.3 %), and 1000 seed weight (187.8 g) were observed when using a complex system with a single dose of NPK.
