Abstract

Drought disrupts plants physiological processes, which has a further impact on soybean production. Salicylic acid is a biostimulant that contributes as a plant stress mitigator. The purpose of the study was to investigate the physiological response and production of soybean plants as influenced by salicylic acid foliar spray in drought conditions. The study used Grobogan variety soybean as plant material. The research was carried out in August – October 2022 at the Greenhouse and Laboratory of Plant Physiology and Breeding, Faculty of Animal and Agricultural Science, Universitas Diponegoro, Semarang City. The study used a 3x3 Factorial Complete Randomized Design with 3 repetitions, so 27 experimental units were obtained. The first factor is drought stress with 3 levels (80% KL, 60% KL, and 40% KL). The second factor is the concentration of salicylic acid with 3 levels (0 mM, 0.5 mM, and 1 mM). The parameters observed were leaf chlorophyll, relative water content, stomata density, number of flowers, fresh weight of pods, dry weight of pods, and number of seeds. A 40% KL drought stress treatment decreased chlorophyll levels a, b, and the total, number of flowers, fresh weight of pods, and dry weight of pods. The application of salicylic acid with a concentration of 1 mM was able to increase the fresh weight of the pods.
