Abstract

Introduction. The article presents the comparative assessment of applying various doses of growth stimulant in soybean cultivation.
Goal. The research determines the effectiveness of applying multifunctional humic growth stimulator potassium Lignohumate brand AM with a high content of fulvic acids on soybean yields under irrigation conditions.
Methods. The work was carried out in 2021-2023 at an experimental irrigated site in the north of the Astrakhan region. The soil of the experimental site is light chestnut, the subtype is brackish. The humus content in the arable layer was 0.9%, mobile phosphorus and potassium (according to Machigin) – 24.3 and 441.5 mg/kg of soil, respectively, and the granulometric composition was medium loamy. Field experiment scheme: control (without treatment); Potash lignohumate, 30 g/ha, 50 g/ha and 70 g/ha.
Results. The analysis of weather conditions definitely revealed that the growing season of the conducted research was extremely dry. The options that use less water to form marketable products were with a consumption rate of 50 and 70 g/ha. The water consumption coefficient in these variants was 625.8 m3/t. The consumption differed significantly from both the control and the lower-consumption version of the drug. It was found that the maximum number of grains per 1 plant is 138.3 pcs., the weight of grains per 1 plant is 22.3 g., and the weight of 1000 grains is 212.3 g. they were obtained in a variant with a consumption rate of 50.0 g/ha.
Conclusions. The use of the AM grade potassium Lignohumate preparation at a concentration of 50.0 g/ha allowed to obtain a soybean yield of 4.5 t/ha by improving the structural parameters of the crop. It is possible to recommend this drug in the specified rate of use for soybean cultivation under irrigation conditions to realize the genetic potential of productivity.
