The effect of selenium on the nitrogen content in barley grain

Abstract

Selenium, which is an essential element, is supllied in humans and animals due to receipt of plant products, and in particular crops. Its relationship with nitrogen gives an idea of the participation of selenium in plant metabolism. In pot experiments were conducted studies of foliar effect of sodium selenite on the growth and development of barley. The high responsiveness of plants on foliar selenite utilization is observed, which showed not only the content of selenium in the straw, but also in the grains. It was also studied the relationship between high selenium content in the grains and the supply level of the main plant nutrients (NPK). As a result, some changes in nature of selenium effect on nitrogen metabolism and some changes in the amino acid content have been identified.
