The influence of growth regulators on the yield of potato tubers of seed material in the conditions of the mountainous zone of the Kabardino-Balkar Republic

Abstract

With sufficient provision of mineral macro elements of the soil and an optimized fertilizer system, growth regulators contribute to an increase in the number of tubers laid on one bush. The use of growth regulators dampens the influence of the weather conditions of the year on the diet of plants, which contributes to the growth and development of potatoes. The complex application of growth regulators contributes to the production of leveled seed material, to increase the yield of the seed fraction twice. The effectiveness of using Agrovin Mg-Zn-B is higher than Agrovin Ca by 13%, in terms of total productivity, and in terms of seed yield by 7.8%. Agrovin Ca, in comparison with Agrovin Mg-Zn-B, has a more directed effect on increasing the mass of the tuber than on the number of tubers per plant. The complex use of Agrovin Micro 0.5l/t + Agrovin Mg-Zn-B is more suitable in seed plantation technology, and Agrovin Micro 0.5l/t + Agrovin Sa for the production of table potatoes.
