Abstract

The article presents the results of researches on influence of various doses of fertilizers on the productivity of barley grain, crude protein content in it and nutrient consumption per production unit. Fertilizers increased productivity by 0.6–2.8 t/ha and crude protein content in the grain by 1.9–4.2%. The calculated fertilizer doses almost doubled the yield as compared to the control group, reaching 4.6–5.2 t/ha, and brought the actual nutrient consumption per ton of grain with the corresponding amount of straw closer to the planned levels.

Keywords

barley, nitrogen, phosphorus, potash fertilizers, productivity, nutrient consumption.
