FODDER EFFICIENCY AND QUALITY OF THE PEA-BARLEY MIX DEPENDING ON APPLICATION OF FERTILIZERS ON SOD-PODZOLIC LIGHT LOAMY SOIL

Abstract

In researches with a pea-barley mix on sod-podzolic light loamy soil the application of increasing doses of organic fertilizers of 20-60 tha^-1 has increased gathering of feed units on 0,58-2,75 tha^-1 at the general efficiency of 6,10-9,38 tha^-1 of fodder units and a recoupment of 1 ton of manure of 29,0-48,0 f.u. Adequate provision of 1 f.u. of a digestible protein in variants with entering of organic fertilizers has made 172-223 g, the maintenance of crude protein - of 17,3-21,7%. Entering of full mineral fertilizer N₆₀P₄₀K₈₀ promoted additional gathering of 1,21-1,83 tha^-1 of f.u. at a recoupment of 1 kg NPK of 6,7-10,2 f.u. Specific carrying out of nitrogen with 1 ton of green weight of a pea-barley mix has made of 6,6-8,9 kg, phosphorus - of 2,1-3,2, potassium - of 6,3-8,1, calcium - of 1,3-1,6, magnesium - of 1,0-1,2 kg.
