 Common beans – valuable high-protein crop, has a multilateral use in the national economy. Expansion of industrial production of common beans is due to the growing demand for it on domestic and global market.Most part of grain of this crop is grown in the private sector at small areas (mainly at household plots), does not meet demand for its products, so there is a question about sown areas increasing. Purpose of research was to establish peculiarities of common beans productivity formation varieties Mavka, Perlyna, Nadiia, depending on doses of mineral fertilizers and seed inoculation on sod-podzolic soils of Transcarpathia of Ukraine.The experiment was laid on collection-demonstrative field of PE NULES of Ukraine Mukachevo Agrarian College in Transcarpathian region. Results of research allowed establishing that seed inoculation provided an increase in grain yield from 1,3 to 16,3%, depending on variety and fertilizers. It is noted that the higher was dose of fertilizer application, the lower was percentage yield of beans increasing due to inoculation.Application of mineral fertilizers in dose N90P60K30 without seed inoculation promoted an increase in yield of beans to 2,34 t/ha for variety Mavka, 2,45 t/ha for variety Perlyna and 2,15 t/ha for variety Nadiia. With inoculation of seeds by Rizobofit, yield of beans was higher for fertilizer application in dose N60P40K20 and reached 2,54 t/ha for variety Mavka, 2,63 t/ha for variety Perlyna and 2,36 t/ ha in variety Nadiia. Nitrogen nutrition influenced on increasing protein content in the grain of studied varieties of common beans.Variety Nadiia was characterized by high palatability and quantity of protein in the grain, content of which on average over the years of research varied within 24,9-27,4%.
