Results of a research of cultivation of Vicia sativa L. together with colza and mustard white. The lack of scientific research on the use of Vicia sativa L. as a compacting crop of colza and mustard white for the purpose of forming highly productive resistant to lodging mixed agrophytocenosis determines the relevance of the research data. Data on allelopathic interference of cultures, elements of crop structure, yield in single-species and mixed crops are provided. Binary crops of Vicia sativa L. with colza and mustard white reduce the seeding rate of Vicia sativa L. on 55-70 % in comparison to single crops. At the same time, the lodging of Vicia sativa L is reduced to 2-3 points, against 4,7-5,0 in single form, the yield of the mix is increased by 37,5-68,1% in mixture with colza and 8,0-40,7% in mixture with mustard. The advantage of cultivating spring Vicia sativa L. in binary crops is especially evident in conditions of precipitation deficit at elevated temperatures. Single-species crops of Vicia sativa L. sharply reduce the yield, and in mixed crops a positive allelopathy appears. In the crops of spring Vicia sativa L. with mustard and colza, a distinct varietal reaction of Vicia sativa L.
