BIOLOGIC EFFECTIVENESS OF HUMIC NATURE PREPARATION APPLICATION IN SPRING WHEAT CULTIVATION

Abstract

The results of three-year studies (2016-2018) of the effect of the organic-mineral preparation of humic nature “Humat + 7”of C 2 label on the spring wheat yield and its constituent elements are presented. As a result of the drug application in variants with a tank mixture preparation additional stems were formed in plants. The productive tillering coefficient was 1.34, 1.27 and 1.36 over the years. The density of the productive stalk was 12.3, 15.7, 19.8% higher in comparison with options 1 and by 1.9, 4.9, 8.7 % with control 2. It was established that the pesticides and a humic nature agrochemicals application are contributed to an increase in the productivity of spring wheat in the Ryazan region by 17 - 43%. Full complex application of the preparations (option 6) provided the greatest increase – by 1.1 t / ha. The yield was 5.37 t / ha in 2016, 7.68 t / ha in 2017, 5.11 t / ha in 2018, as it was formed due to the high productive stalk, the number of grains and their weight per ear. It was determined that, depending on the use of the drug, the net income and the level of profitability are higher, respectively, by 21 – 46 and 8 – 24% than in the control without a dressing agent and by 5 – 27 and 4 – 26% – with the introduction of pesticides. At the same time, the profitability increases most significantly in the 4 and 6 options in comparison with the control.
