Purpose: to study modern growth-promoting agents that have a positive effect on the agrobiological and economically valuable characters of peanut crops under drip irrigation on light chestnut soils of the Lower Volga region.
Materials and methods. The study was conducted at the experimental plot of the Precaspian Agrarian Federal Scientific Center of the Russian Academy of Sciences over a period of three years. The object of the study was the Astrakhansky 5 peanut variety, obtained by the center’s staff. The experiment was conducted in triplicate. The agents used were chosen for their growth-promoting and protective effect on peanut seeds and plants in the arid conditions of the Lower Volga region. In addition, they are environmentally friendly, cost-effective and easy to use. Phenological and laboratory studies were conducted using generally accepted methods.
Results. Based on the experimental data obtained, it was determined that the peanut ripening period was 122–135 days. The application of the studied agents for seed soaking accelerated the seedling emergence. Thus, seedlings soaked in Cytodef-100 appeared already on the tenth day, while in the control they appeared only on the fifteenth. The use of Cytodef-100 contributed to a reduction of the ripening period by seven days. The highest productivity indicators were also noted with the use of Cytodef-100. Thus, the productivity of one plant ranged from 56.2 to 63.7 g, the weight of 50 beans reached 159.3 g, the yield was 6.1 t/ha. When using Berkana, water-soluble concentrate, the corresponding productivity indicators ranged from 49.3 to 52.7 g, 127.3 g, 5 t/ha; when using the “Rezvy Start” Chelate, the yield was from 49.9 to 56.9 g, 140.4 g, and 5.4 t/ha.
Conclusion. The most effective growth-promoting agent was Cytodef-100, which yielded the highest results in almost all peanut treatment variants.
