THE QUALITY OF SPRING TRITICALE GRAIN DEPENDING ON THE EXCHANGEABLE MAGNESIUM SUPPLY OF SOD-PODZOLIC LOAMY SOIL AND RATES OF MINERAL FERTILIZERS

Abstract

It was found in field experiments that the content of crude protein in the grain of spring triticale and its output per unit area had been increased with increasing of soil exchangeable magnesium supply up to 138-147 mg/kg of soil. The maximum value of the sum of critical and indispensable amino acids 7,02-7,17 and 24,0-25,31 mg/kg of grain, respectively, was obtained in fertilized trial with the equivalent ratio in the soil Ca:Mg cations around 5 and the ratio of K:Mg around 0,6.
