EFFECT OF BIOFERTILIZER KALIPLANT ON QUALITY OF GRAIN CROPS GROWING ON LUVISOL LOAMY SANDY SOIL

Abstract

The application of biofertilizer Kaliplant (K-mobilizing bacteria) was found to affect grain crops quality. More reliable effect of Kaliplant on grain quality was observed under deficit of mobile potassium in luvisol loamy sandy soil. Significant increases of protein contents in winter rye (0.4-0.5%) and winter triticale - 0.7-1.3% were found. Introduction of Kaliplant resulted in the improvement of amino acid composition of grain under following conditions: for winter rye under К₂О content in soil in diapason of 105-222 mg/kg, for winter triticale and spring wheat - 94-164 mg/kg.
