The effect of the drug Atlante Plus on the formation of the solanum lycopersicum L. crop in the central zone of the Krasnodar Territory

Abstract

Physiologically active substances play an important role in the formation of the vegetable crops harvest, influencing the timing of product receipt, its size and quality. In the Krasnodar Territory, the leading place among vegetable crops in the open ground is occupied by solanum lycopersicum L., the crop stability of which is complicated by high temperatures and insolation during the growing season. Using the drug Atlante Plus makes it possible to increase the stress resistance of plants, provide the necessary phosphorus-potassium nutrition. Studies conducted in 2021 in the central zone of the Krasnodar Territory revealed the drug effectiveness for pre-sowing seed preparation and spraying of solanum lycopersicum L. plantings during budding. Soaking seeds in the drug solution with the concentration of 0.005 % increased their germination energy and laboratory germination, activated growth processes in seedlings. Spraying of vegetat-ing plants with a solution of the same concentration increased the leaf surface area by 28 cm2, and the productivity of one plant – by 180 g.
