Abstract
The article presents materials on the study of the effect of mineral fertilizers on the yield and grain quality of the second corn in a nine-field crop rotation on gray-earth meadow soil of the educational and experimental farm of the Kyrgyz National Agrarian University. Intensification of grain production, including corn, is a very important factor. In recent years, the efforts of scientists and practitioners in the country have created a potential that allows you to get 80-130 kg/ha of corn grain. The production received promising, high-yielding varieties and hybrids of corn. Since the time of the Union States, up to the present time, the use of fertilizers, and the introduction of new varieties and hybrids of corn into production have been important methods of increasing the yield of agricultural crops, including corn. Ukuruza grain in terms of feed value is one of the best among forage crops, it is a raw material for the food industry and an indispensable component in the production of compound feeds. Research on the development of a system of maize fertilizers in specific soil and climatic conditions has not been carried out before, so the topic of research is very relevant and of great practical importance. The research was carried out in a long stationary experiment with fertilizers, founded in 1967 by the staff of the Department of Agrochemistry. The experimental field of the stationary experiment is divided into three equal fields, where a nine-field crop rotation was introduced and mastered
