PRODUCTIVITY AND NUTRITION ELEMENT REMOVAL UNDER CULTIVATION OF MAIZE ON SOD-PODZOLIC LIGHT LOAMY SOIL

Full Text:

Abstract

In research on sod-podzolic light loamy soil the use of various kinds of organic fertilizers and industry waste has enhanced maize productivity by 5,0-31,2 c/ha of fodder units (f.u.), a full mineral fertilizer - on 39,4 c/ha of fodder units, at the general productivity in the fertilized variants of 125,0-156,2 c/ha of fodder units. The highest productivity parameters of maizy are received in variants with entering N90+30P60K120 into a combination to 60 t/ha of straw manure of cattle (productivity of green mass - 781 c/ha, dry matter gathering - 156 c/ha, gathering of fodder units - 156,2 c/ha, gathering fodder protein units - 146,9 c/ha, the content of crude protein - 11,1%, digested protein - 14,69 g/kg of green mass at security 1 f. u. by digested protein at level of 73,4 g.) and to 60 t/ha of divot and manure compost (productivity of green mass - 769 c/ha, dry matter gathering - 153,8 c/ha, gathering of fodder units - 153,8 c/ha, gathering fodder protein units - 139,3 c/ha, the content of crude protein - 10,3%, digested protein - 13,5 g/kg of green mass at security 1 f. u. by digested protein at level of 67,7 g).
