INFLUENCE OF MICROBIAL COMPOSITION AND ITS COMPONENTS ON GROWTH, DEVELOPMENT AND YIELD OF AGRICULTURAL CROPS

Abstract

Plant growth promotion effects of monoinoculants Azospirillum brasilеnse , Bacillus circulans и Trichoderma longibrachiatum and their composition on inoculated plants were observed in laboratory and field conditions. The efficiency of mono- binary and triple inoculants was studied in the field experiment on Luvisol sandy loam soil on loess loam characterized by different extent of water erosion development. Most significant responses of spring barley grain (5,2 and 4,9 c/ha under yields values 61,4 and 57,9 c/ha) were obtained as a result of triple inoculant application ( A. rasilense + B. сirculans + T. longibrachiatum ) at watershed and weakly eroded soil.
