On the moderately cultivated sod-podzolic soil of the centre of Nonchernozem zone of the Russian Federation yield of haylage and grain of peas-wheat mixtures 4,6-8,4 t/ha and 2,4- 3,4 tons/ha (89 to 100% of maximum achieved) was achieved by introducing Р80К110 and N30Р80К110 depending on composition, grain yield of pure crops of peas and maple pea in this case achieved 3,2-4,2 t/ha (86-100%). These options and crop residues into arable layer additionally come 60- 130 kg/ha of symbiotic fixed nitrogen (KF 0,39-0,74) with the enrichment of the soil 12-73 kg/ha. Estimated increase of possible grain yield of subsequent winter wheat from Nbiol. can reach 6-10 t/ha.
