The role of row crop predecessors in controlling weediness and increasing the productivity of rapeseed and rapeseed seeds

Practice shows that the demand for oilseeds is currently very high. Having the potential of large processing capacities in the southern part of the Non-Black Earth Zone of Russia, oilseeds are in high demand, characterizing rapeseed and rape as high-margin crops in agricultural production. The study of the influence of row crop predecessors on the productivity of cruciferous oilseeds in the conditions of this region is interesting and relevant, which served to determine the direction of research. The article presents data on determining the effectiveness of predecessors on weediness, growth and development, productivity of agrocenoses of rapeseed and rape of spring forms. On the dark gray forest soils of the Ryazan region, the maximum yield of oilseeds of rape and rape was obtained on the variants where the predecessor potato was chosen (2.80 t / ha for rape, 2.68 t / ha for rape), the minimum yield of rape and rape was obtained from the predecessor of corn for grain (2.55; 2.44 t / ha, respectively). A direct dependence of the weediness of crops to the yield of oilseeds of the studied crops was revealed.
