Foliar application of nutrients for spring barley cultivation in arid conditions of Middle Volga

Аннотация

The aim of this work is to study the effect of complex fertilizers containing macronutrients and micronutrients in a chelate form, Nutrivant Plus Cereal and Helatonik, applied as foliar nutrients, on the grain yield and the quality of Volgar’ spring barley. Grain yield increases to 26% in the years of insufficient moisture (HCS = 0.4–0.6). Moisture availability during the period from mid-May until the end of June (r = 0.86) has a significant effect on the volume of spring barley harvest. As a result of the use of the foliar additives, the quality of grains remains high while the yield grows.
