Abstract

For the first time under the conditions of the Altai Region, studies were carried out to evaluate the effect of pre-sowing treatment of spring wheat seeds and the use of microbial fertilizers based on nitrogen-fixing and phosphate-mobilizing bacteria Azofit N and Azofit R at sowing, and the effect of reduced rates of pre-sowing application of mineral fertilizers against the background of using microbial fertilizers on field germination of spring wheat seeds in soil areas with different levels of fertility. Before starting the experiment, the areas of low, medium and high levels of fertility were identified on the field based on the data from the Cropio platform; and a full set of experiment variants was implemented in each of these plots. The greatest plant density and field germination of spring wheat was formed in the areas of medium fertility in the variant of reduced rates of the basic l fertilizers to 85% when using microbial fertilizers; in the areas of low fertility - by reducing to 70%, and in areas of high fertility - by reducing the rate to 70 and 50% of the basic level of fertilizers. Regression analysis showed that the site factor of soil fertility of the field was more significant. The regression coefficient made R = 0.69. This is largely due to the applied rates of fertilizers when accompanying application of microbial fertilizers and the diversity of soil fertility in individual sections of the fields in the experiments.
