Effectiveness of the action of humic preparation on potato productivity

The article discusses the effect of humic fertilizer Ekorost on the productivity of potato varieties cultivated in the Ryazan region. Humic fertilizers and their application are one of the innovative techniques used in potato growing technology. Stimulation of the development and growth of plants is carried out during the pre-planting treatment of potato tubers. At the same time, there is an increase in the level of metabolism in the treated tubers, which leads to the germination of eyes at an earlier date and intensive growth of stems at the beginning of the growing season. An increase in the yield of potatoes is positively affected by an increase in the level of metabolism and the power of development of the bush itself. The use of humic fertilizers increases the intensity of respiration and photosynthesis, which leads to an increase in the content of chlorophyll, the total amount of sugars in the leaves, and ascorbic acid. According to the results of the studies, it was found that the treatment by Ekorost of the studied potato varieties contributed to the increase in stems. Most of them were observed in the third variant of the experiment of the Koroleva Anna cultivar - 5.1-.5.6 pcs. / Plants, or 14.6-16.7% more than in the control. In the Koroleva Anna variety, the biological yield index in the third variant of the experiment increased in relation to the control by 2.81 t / ha, the Red Scarlett variety by 1.55 t / ha and the Kolobok variety by 2.57 t / ha
