INFLUENCE OF PHOSPHORUS-MOBILIZING BACTERIA ON GROWTH, YIELD AND PHYTOPATHOLOGY STATE OF CEREAL CROP GROWINGS ON LUVISOL LOAMY SAND SOILS

Abstract

Tested P-mobilizing bacteria were found to promote plant development at earlier stages of ontogenesis that provides the increase of plants adaptive potential. As a result of inoculation with P-mobilizing bacteria the root volume of plants was increased by 14-30%, root biomass - by 11-32%, stem biomass - by 6-19% compared control treatments. Inoculation of winter triticale and spring barley sowings with P-mobilizing bacteria resulted to reduction of indices of spread and development of root rot infection by 1,2-1,3 and 1,3-2,3 times respectively. Application of P-mobilizing inoculants resulted in the yield increase of winter triticale and spring barley due to combination such factors as plant growth promotion, fungi static effect and P-mobilization.
