Influence of crop rotation factor and fertilizer system upon productivity and quality factors of grain of winter wheat in field rotations of Right-bank Forest-steppe region

Abstract

Objective. Determine the influence of predecessors, the period of return to the previous place of cultivation and various fertilizer systems on the yield and quality of winter wheat grains in short-rotation crop rotations. Methods. Field, laboratory, comparative calculation. Results The highest yield of winter wheat (4.63 t / ha) was obtained after soybean for organo-mineral fertilizer system in crop rotation. Grain of winter wheat of the highest quality (11.8% - protein and 22.4% - gluten) were obtained for placing it after the clover on 2 slopes for making N70P50K60. Conclusions For the cultivation of winter wheat on chernozem soils in conditions of sufficient moisture of the forest-steppe of the Right Bank precursors, the period of return and fertilization have a significant effect on the moisture content, nitrate nitrogen in the soil and the level of perturbation of crops.
