Response Of Pasture Grasses To Inoculation With Mycorrhizal Fungi And N- fixing Bacteria

Abstract

The effect of inoculation with “Mycosym TRI-TON” biofertilizer applied singly or in combination with symbiotic and non-symbiotic N-fixing bacteria on the plant biomass, N and P content of some pasture grasses and soil and roots acid phopsphatase activity was studied in a pot experiment. Active and effective symbiotrophic associations pasture grasses – AMF – N-fixing bacteria, suitable for agricultural practices in the creation of meadows and pastures were selected. The best synergetic interactions were established for the combinations AMF + Rh. melliloti 116 for lucerne, AMF + Rh. trifolii 325 for red clover and for gramineous grasses – AMF + Az. brasilense 107.
