Abstract
In 2017-2019, we conducted the field and vegetation experiments at the field station of Russian State Agrarian University, Moscow Timiryazev Agricultural Academy to study the effect of sodium selenite on the yield and grain quality indicators of white lupine, Dega variety, and spring wheat, Yubileynaya-80 variety. The best way found to use selenium is to spray vegetative plants with 0.01% aqueous sodium selenite solution. The studies have shown an increase in grain yield by 15-17%, crude protein content by 9-15% and crude fat content by 5-7% when treated with sodium selenite. The obtained grain yield of white lupine has a higher feed and nutritional value and is suitable for feeding animals and preparing various types of feed and feed additives. The optimal way to use selenium is spraying vegetative plants before shooting. Treatment with sodium selenite contributes to an increase in wheat yield by 1.5 times. We have established the positive effect of sodium selenite on the quality indicators of wheat grain. An increase in the content of raw gluten and glassiness of grain has been noted, which determines high bread-making qualities.
