EFFECT OF BINARY INOCULANT A. BRASILENSE + B CIRCULANS ON YIELD AND QUALITY WINTER WHEAT GROWING ON ERODED SOD-PODZOLIC LOAMY SOILS

Abstract

Binary inoculant application resulted in the yield increase of two cultivars of winter wheat at different slope elements: not eroded, moderately - and severely eroded sandy loam soils on morain and loess loams. The effect from binary inoculant A. brasilense + B. сirculans is increased in stress conditions on eroded soils. In the field experiment on not eroded sod podzolic loamy soil on moraine loam the responses of winter wheat to inoculation varied in diapason of 1,9-3,5 c ha^-1, on severely eroded soils - in diapason of 3,2- 3,9 c ha^-1 of grain. Application of binary inoculant resulted in the improvement of winter wheat grain quality in respect of protein content and 1000 grains mass.
