Effectiveness of a preparation based on animal effects on winter and spring wheat

Abstract

   The results of testing a drug obtained from livestock waste containing fulvic acids on winter and spring wheat are presented. The prescription was obtained by treating an aqueous infusion of chicken manure and pig waste with 60% nitric acid. Before use, the drug was diluted with water in a ratio of 1:100. The working solution had a pH of 6.7–6.9. The specified pH value of the working solution prevents the possible adverse effect of the drug on other agrochemicals when using tank mixtures. Pre-sowing treatment of winter wheat seeds with the resulting preparation, at a consumption rate of 0.1 l/t, increased the area of flag leaves, which had a significant positive effect on yield, by 1.8 times compared with the control. The biomass of plants treated with the drug was 1.3 times greater than in the control. Pre-sowing treatment of seeds with the medication at a consumption rate of 0.1 l/t led to an increase in the yield of winter wheat in the conditions of the Belgorod region by 0.44 t/ha, or by 6.8 %, as well as the content of gluten protein in grain by 2.0 % and reduced infection of seeds with Alternaria. Spraying spring wheat during the stem growth phase (two nodes) increased the yield by 0.73 t/ha or 20.8 %. The use of the drug for pre-sowing seed treatment significantly reduced the sensitivity of spring wheat plants to herbicide stress. The increase in yield under the influence of the medicine was achieved by increasing the number of ears by 11.2 % and by increasing the number of grains in an ear by 8.3 %.
