This article presents the results of research of the influence of bio-and humic preparations on the productivity of spring multi-row barley. It was concluded that they have an effective influence on plants. Studies have shown that when processing crops with potassium HUMATE in the tillering phase and entering the tube, the largest numbers of barley plants were preserved for harvesting and a higher productive bushiness compared to the control was observed. The third use of the preparation slightly reduced studied indicators. It was also established that, on average, for 3 years of research, the use of potassium HUMATE in the tillering phases, entering the tube and earning contributed to a significant increase in the number of grains in the ear and the mass of 1000 seeds. The research results indicate that the yield of spring multi-row barley of Vakula variety significantly changed according to experiment varieties. The maximum increase was provided by three-time treatment of crops with potassium HUMATE. After conducting a correlation and regression analysis, it can be concluded that the yield of spring barley was equally dependent on the elements of productivity. There was a close positive relationship. Consequently, the productivity of spring multirow barley plants is significantly influenced by bio-and humic preparations.
