Responsiveness to inoculation and application of micronutrient fertilizers in common vetch (<Emphasis Type="Italic">Vicia sativa</Emphasis> L.) new varieties at seed production

The responsiveness of common vetch varieties to inoculation with Rhizobium leguminosarum biovar-viciae of different genotypes and applications of molybdenum and boron micronutrients has been revealed. It is shown that the effect of interactions between molybdenum and boron on the plants at the joint application is nonadditive. The artificial colonization of seeds by the complementary strains of root nodule bacteria and the molybdenum treatment are expedient to increase the efficiency of the symbiotic interactions between rhizobia and common vetch varieties. Inoculation with strain no. 145 and supplementation with molybdenum improved the seed yields of the common vetch Valentina and Lugovskaya-98 varieties by 20% and 17%, respectively.
