Abstract: The purpose of the research is to increase the yield and quality of spring barley grain by various tillage systems and fertilization. The conducted studies of the influence of the tillage method and the use of nitrogen fertilizer N30 on the elements of the spring barley crop structure indicate a positive effect on the number of plants and stems, their height, grain weight from the main ear of spring barley, increasing the value of these indicators to 2.2-3.2%. The yield, pro-tein content and vitreous content of the endosperm, depending on the conditions of the experiment, had the highest values in the plowing variant with a fertilized background, the lowest in the variants of fine processing, without autumn mechanical processing and without fertilizers. The natural weight of grain, determined depending on the systems of tillage and fertilizers, had similar values, changing slightly. The level of profitability of spring barley grain production, with the use of tillage systems – plowing and mineral fertilizer – decreased by 11% and 15%, respectively, compared with options without autumn mechanical processing and without fertilizers. Thus, the application of mineral fertilizers is less effective, and the use of a tillage method – without autumn mechanical treatment when cultivating spring bar-ley is economically feasible. Correlation analysis of yield and protein content in barley grains has shown that the de-gree of dependence of the traits is medium or strong, both straight and reverse. The determination coefficient in the regression equation is close to one and describes well the dependence of features. When analyzing the dependence of vitreous on protein content, a significant close correlation was established, which shows that the increase in one indicator is associated with the increase in the other.
