Abstract

In researches on sod-podzolic light loam soil the highest productivity of green mass of spring rapeseed is received at N110Р60К120 application on background of aftereffect of 40 and 60 t/ha manure - 41,5-42,9 t/ha at average response of yield from mineral fertilizers - 15,7 t/ha, from aftereffect of organic fertilizers - 4,7 t/ha. Application of organic and mineral fertilizers on given variants has provided green mass with optimum zootechnics parameters: gross output of feeding and proteinogenous units in average was 5,91 and 7,17 t/ha correspondingly, the contents of crude protein - 17,4%, supply of feeding unit by digested protein - 119 g at ratio K/(Са + Mg)=1,71.
