EFFICIENCY SPRING RAPE AND CARRYING OUT OF NUTRIENTS DEPENDING ON FERTILIZER SYSTEM IN CULTIVATION ON PODZOLUVISOL LOAM SOIL
Abstract
Influence of various fertilizer systems in spring rape cultivation on podzoluvisol loam soil is studied. It is established that mineral fertilizers application in doses N90Р60К120 promoted formation of seeds spring rape productivity 28,2 t/ha. Specific carrying out of basic nutrients with 1 t basic and by-product production at the given fertilizer system has made: nitrogen 44,4 kg, phosphorus 21,5 kg, potassium 54,9 kg, calcium 19,1 kg, magnesium 7,6 kg. In researches with summer rape 2010-2011 it is established that depending on mineral fertilizers system indicators specific carrying out of nitrogen and phosphorus below standard. Specific carrying out of potassium (except without fertilizers variant) above standard and in a variant with entering N90+30P60K120 exceeded it twice. Specific carrying out of calcium exceeded standard in 2,7-4,1 time, magnesium - in 3,3-4,1 times.
