The prospects of common vetch cultivation in mixed agrocoenoses in the conditions of Novgorod region

Abstract

Abstract For effective creation of highly productive plant formation, at first it is necessary to identify how the participants of this density interact with each other throughout the growth season. By cultivating mixed agrocoenoses, it is possible to identify this relationship and strengthen the food supply by establishing the optimal method of seeding and its seeding rates with different components. This article presents the main results of a scientific study of mixed agrocoenosis of vetch with different components at different seeding methods and seeding rates in the conditions of the Novgorod region. In the studies, the vetch was cultivated in a mixture with oats, and also pure vetch and pure oats were also sown to compare the results. The table shows the ratio of the legume-cereal component in the seeding rate and the influence of the seeding rate on such indicators as field germination rate, plant livability and the density of plants standing before harvesting. In the course of research, it was found that the optimal way to sow mixed agrocoenosis in the field of crops according to such indicators as elements of herbage productivity, field germination and crop yield is a combined method (1:1). Using this method of seeding, the resulting yield of the herbage of the common vetch reached 22.3 tph (tons per hectare) in comparison with the examining variant of the single-species dropping of the vetch.
