Extraction of Microorganisms in the Cotton Rhizosphere and the Study of Their Practical Significance

Abstract

This article provides the research results on that in the conditions of Khorezm region’s dry climate and saline soils, pure cultures of bacteria involved in the mobilization of mineral phosphates were isolated, morphologically analyzed and found to belong to the genus Bacillus as gram-negative rods. Bacterial activity was monitored – solubility activity of water-soluble phosphate and antagonistic properties of soil-borne fungi such as Alternaria alternata Rhizoctonia solani, Fusarium solani Verticillium dahlia were studied. When cotton seeds were processed with the association of bacteria found to be active and encapsulated with composts, high yields of cotton were obtained in the bacterial-treated variants. The results obtained are important for the conditions of saline soils and can be used to prevent phosphorus deficiency in crops and to obtain high yields from cotton.
