Abstract
The article presents the results of studies on the effect of the combined use of mineral fertilizers and growth regulators of various spectra of action on the yield of various hybrids of corn cultivated for grain in the conditions of the Central Black Earth Plant. Differences in the responsiveness of hybrids to increasing doses of applied fertilizers and applied agrochemicals were established. The most productive maize hybrids have been identified. The efficiency of the combined use of increasing doses of mineral fertilizers and various plant growth stimulants, new forms of macro- and micronutrient fertilizers, physiologically active substances in the formation of grain corn yield is presented.
