Effectiveness of fertilizer systems for winter rape on sodd­podzol loam soil

Abstract

The most effective in cultivating winter rapeseed was the use of complete mineral fertilizer N30+90+60P20K70 in combination with microfertilizers MicroStim-Manganese, MicroStim-Boron and plant growth stimulator Aminofol Plus against the background of the 2nd year of aftereffect of straw manure, which ensured the production of 38,9 c/ha of oil seeds containing 21,4 % protein, 48,3 % oil with 7,4 c/ha of crude protein yield and 79,3 c/ha of feed unit yield. With such a fertilization system, each kilogram of mineral fertilizers paid for 4,7 kg of oil seeds In a technological experiment on sod-podzolic loamy soil.

The standards for the specific removal of basic nutrients by winter rapeseed have been clarified. They make up are (kg/t): N – 31,8–37,9, P2O5 – 15,8–16,2, K2O – 21, 2–22,9 in depending on the fertilizer system used and the level of yield.
