Influence of foler feeding with humic fertilizers on the productivity and quality of spring wheat grain

Research to determine the effectiveness of the use of humic fertilizers in the cultivation of spring wheat was carried out in 2021-2023. In the experiments of the Department of technologies of highly productive rational land use on the basis of the Federal State Budgetary Budgetary Institution "Kursk FANTZ" of the Kursk State Agrarian University. The effectiveness of humic fertilizers of domestic (ECO-SP) and foreign production (Fulvigrain Classic, Humiful Pro) in seed treatment and double treatment of spring wheat crops in the tillering phase and the exit phase into the tube was studied. The soil of the experimental site is a typical powerful chernozem of heavy loamy granulometric composition. A variety of spring wheat Daria. It was found that the treatment of spring wheat seeds with fertilizers based on humic acids increased their germination energy by 2-4%, laboratory germination by 4-5% in comparison with the option where the seeds were not processed. When processing seeds and double-processing crops in the "tillering" phase and the "exit into the tube" phase, humic fertilizers increased the yield of spring wheat by 0.47-0.55 t/ha or by 12.6-14.8%, while the gluten content in the grain increased by 0.6-1.3%, the protein content by 0.5-0.9%, starch – by 1.4-1.8%. The use of humic fertilizers in the cultivation of spring wheat was economically beneficial. The highest net income was obtained from seed treatment and double treatment of crops with domestic humic fertilizer ECO-SP – 19315 rubles/ha, with a profitability level of 83.3%. The value of the conditional net income from the use of humic fertilizers Fulvigrain Classic and Humiful Pro was lower and amounted to 18913-18702 rubles /ha, and the level of profitability, respectively 79.5-80.6%.
