Creating a biological product using Nitrogen-fixing bacteria before sowing wheat
Abstract
Based on the associations of nitrogen-fixing bacteria of the Rhizobium sp. and Azotobacter sp. genera, biofertilizers have been developed for increasing the wheat yield in Northern Kazakhstan. Among nodule bacteria and azotobacters, nine promising strains of microorganisms that can stimulate plant growth, fix nitrogen, and exhibit antagonism to phytopathogenic micromycetes have been isolated. Three associations have been tested in the vegetation experiments. According to the results of the experiment, association No. 2 that was tested in field studies upon introduction before sowing spring wheat was selected. The biofertilizer has increased the wheat grain yield by 275 kg/ha.
