EFFECT OF MONO- AND BINARY INOCULANTS ON YIELD AND PHYTOPATHOLOGY STATUS OF GRAIN CROPS GROWING ON LUVISOL LOAMY SAND ERODED SOILS

Abstract

Application of mono inoculants Azospirillum brasilense, Bacillus circulans, Тrichoderma longibrachiatum (sowing treatment) as well as their binary compositions stimulates the formation of generative stems, the increase of grain’s number in spike and spike mass, as well as results in the reduction of pathological process in grain crops growing on different slope elements of Luvisol loamy sand eroded soils. Anti stress action of microbial inoculants provides the increase of grain crop yields on eroded soils. As a rule most significant effects from mono inoculants were obtained on eroded soils (yield responses - 4.3-6.6 %). Binary compositions were effective at different slope elements of Luvisol loamy sand eroded soils (yield responses 3.4-7.9 %).
