Abstract
Aftereffect of biological nitrogen produced by different plant genotypes was studied in gray forest and chernozem meadow soils. High efficiency was established for availability of fixed nitrogen by oats after super nodular form of peas. In the second year of aftereffect the yield gain with regard to the breed amounted to 11 % and 49 % on gray forest and chernozem meadow soils, respectively.
