Possibility of creation of effective algobacterial consortia with high nodulе ability of rhizobial cells is experimentally proven. Pre-sowing bakterization treatment of chickpea seeds provided the increase of the productivity of plants such polyfunctional cyanorhizobial complex by 43,4% in the conditions of the field experiment. It may serve as a base for biological technology of growing chickpea for obtaining of ecologically safe production. We brought under cultivation 12 strains associated with a strain of cyanobacteria Nostoc linckia 144, identified by their morphological, cultural, physiological, and biochemical properties. We revealed that on nitrogen-free substrate some 62 and 77% of strains satellite cyanobacteria and algae itself positively affect tuberization of soybeans and chickpeas and increase the dry weight of aboveground plant up to 28,6-35,7%; under condition of Southern black soils the bacterization of strains of Microbacterium laevaniformans KAGK and Mesorhizobium siceri raised the ground dry weight of plants per 0.82 g / plant (21.1%) compared with mono-farmery. We created the effective algological bacterial consortium of high activity of Mesorhizobium siceri cells, whose number was 9.7 h105 BUOD / mL, which exceed by two orders of magnitude higher the monoculture rhizobia. We proved experimentally the efficiency of usage of cyanobacteria combined with nodule bacteria in agrobiotechnology and suggested the high efficiency of prebacteryzation of seed by cyan-rhyzo-consortium of chickpeas which ensuring the increase of plant productivity by 43.4%.
