The influence of various types of organomineral fertilizers using a biohumin complex on the yield and quality of potato tubers

The use of organomineral fertilizers in the form of granules and pellets with the addition of a humic biocomplex when growing potatoes in the field had a beneficial effect on the yield and quality of potato tubers. A significantly higher yield index, on average for three years - 26.74 t/ha, was obtained when introducing into the soil of WMD in the form of treated pellets and vegetative potato plants with a biohumin complex, which allowed collecting tubers in addition to the control 6.99t/ha - 9.65 t/ha. In the variant with the introduction of WMD + BHA into the soil in the form of granules and with the treatment of plants during vegetation, the yield of potato tubers was 22.19t/ha, which is higher than the control by 2.46 t. The collection of dry matter increased by 3.89 t/ha and amounted to 5.56-4.69t. Starch accumulation was 2.22-3.22 t/ha, exceeding the control variants by 0.6-3.23%.
