PRODUCTIVITY AND QUALITY INDICATORS OF GRAIN BARLEY DEPENDING ON VARIETY FEATURES AND LEVEL OF MINERAL NUTRITION

The article presents experimental data on the yield of various varieties of grain of spring barley, depending on the use of mineral fertilizers and their influence on the accumulation of mineral nutrition in barley plants and some economic valuable traits. The studies were carried out on ordinary black soil in the conditions of the central black earth. The influence of fertilizers on the content of nutrients in plants, yield and quality of grain on various varieties of spring barley is considered. It has been established that with an increase in the level of fertilization and the direct application of mineral fertilizers for barley, a significant increase in the yield and quality of barley grain is observed. The varietal characteristics of barley in response to the conditions of mineral nutrition are noted.
