Foliar treatment of barley by sodium selenium in controlled conditions

The effects of various selenium concentrations on crop formation, grain quality, and nitrogen and selenium accumulation in spring barley grown on sod–podzolic soil were studied in experiments on vegetation. Optimal amounts of the element were established taking into account different levels of mineral nutrition (NPK) for enriching barley production. Positive effects of selenium on yield, grain quality, and other features of its action on plants were noted. The key role of mineral fertilizers in the effectiveness of foliar treatment of barley was studied.
