THE POTENTIALS OF VEGETATION AND MICROBES INTERACTION IN AGROCENOSES OF LEGUMINOUS PLANTS
The purpose of the study was to find ecologically safe ways of effective functioning of agrocenoses, control of biological processes and using the plant-microbe interaction potential by applying agronomically effective microbe strains to obtain the fertilizing effect on legumes and herbicidal effect on weed plants. The chickpeas Cicer arietinum L. and peas Pisum sativum L., promising and valuable to the Crimean agrocenoses pulse crops, well adapted to the climatic conditions of the steppe zone, were included in the research program. As result of studies, for the first time, it was found that the consortia based on the strains of cyanobacteria could have stimulating and inhibiting effects on the plants of agrocenoses. The pre-sowing treatment of pea and chickpea with cyanorhizobial consortium based on Nostoc linckia-144 and strains of nodule bacteria, specific for pea plants (Rhizobium leguminosarum bv. viciae 261b) and chickpea (Mesorhizobium ciceri 068), made it possible to increase the plants phytomass. The use of the filtrate of the homogenized strain culture of Nostoc linckia-144 had an inhibitory effect on the green amaranth (Amaranthus retroflehus L.) weed plant and did not decrease the yields of pea and chickpeas.
