The paper presents the results of the foliar feeding application in the technology of spring barley cultivation for fodder purposes. The effectiveness of foliar nitrogen fertilizer application and treatment with humic fertilizer «Stimulife» is also discussed in the paper. The use of foliar top dressing in a rate of 30 kg N/ha on an unfertilized background contributed to a 28%-increase in the productivity of spring barley. Subsequent treatment of the crop with «Stimulife» resulted in an additional 12%-increase in productivity. Application of a lower nitrogen rate (20 kg N/ha) on the N75P50K50 background contributed to 11%-increase in barley productivity, while with subsequent treatment with «Stimulife» – to 19%. Foliar fertilizer application at a rate of 10 kg/ha on the most fertilized background (N100P75K75) resulted in an increase in barley productivity of 15%, and with subsequent treatment with «Stimulife» – of 30%. The energy yield of the crop and grain chemical composition was estimated. Differences in the experiment treatments resulted in a change in the chemical composition of barley grain. The combined use of foliar nitrogen fertilizer (30 kg N/ha) with «Stimulife» stimulated an increase in the nitrogen content in barley grain of 50%. Reducing the nitrogen rate to 20 kg N/ha led to an increase in nitrogen in the grain of 44%. The minimum rate of nitrogen in top dressing (10 kg N/ha) allowed to increase the nitrogen content in grain by 16%. Thus, fol
iar differentiated nitrogen fertilization together with «Stimulife» treatment on an increasing background of mineral fertilizers contributed to an increase in the protein content of barley grain from 9 to 17%.
