Improvement of the elements of the technology of sugar corn cultivation in the conditions of the central zone of the Krasnodar Territory

Annotation. The creation of a scientifically based nutrition system for domestic sweet corn hybrids is becoming an increasingly popular research topic, since the correct balance of nutrients is a key factor in achieving high and stable yields in the central zone of the Krasnodar Territory. The aim of the work is to improve the elements of the technology of cultivation of domestic sweet corn, aimed at increasing the yield and quality (sugar content) of cobs through the use of various types of fertilizers. The research is conducted according to the methodology of B. A. Dospekhov's field experience. The scientific novelty of the work lies in the fact that for the first time in the central zone of the Krasnodar Territory, studies are being conducted on leached chernozem with sugar corn hybrids selected by the Lukyanenko National Research Research Center and the elements of its cultivation technology are being improved. Results. In the course of research, it was previously established that the use of ammonium nitrate, at a dose of N40 for pre-sowing cultivation, increases the yield of corn cobs by 10% compared with the control. Foliar top dressing with the microbiological preparation Geostim Fit W increased by 20.2%. In general, the use of factors studied in the experiment: new forms of mineral fertilizers with controlled nitrogen release, application for pre-sowing cultivation, with foliar fertilization of sweet corn with organomineral and microbiological fertilizers, increases the length of the corn cob by 8.5%.
