Productivity and grain quality indicators of white lupine (Lupinus albus L.) variety Degas when using sodium selenite
Abstract The aim of the research was to study the sodium selenite using various methods effect on the yield and quality of Degas variety white lupine grain. To solve these issues microfield experiment on the experimental plot of the Department of agronomic, biological chemistry and radiology of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy was carried out. Thus, it was found that the use of sodium selenite for foliar treatment of plants contributed to the greatest increase in the yield of white lupine plants. The increase in the grain yield of 27% compared to the control was obtained. The increase in the weight of the beans was revealed by almost 2 times. This indicates the influence of sodium selenite on the processes of fruit formation and the process of laying the seed productivity of lupine plants. The greatest effect of foliar treatment of plants with sodium selenite was found. In this variant, the largest increase in grain yield and the highest content of crude protein in the lupine grain were obtained. It is concluded that the use of selenium affects the formation of beans and grains in them, which determines the increase in plant yield.
