Growth and production of soybean (Glycine max L. Merril) varieties in response to waterlogging at vegetative (V5) growth phase by application of gibberellic acid and salicylic acid

[摘要] Waterlogging can cause damage to soybean plants that can decrease the growth and yield. The objective of this research was to measure the growth and production of three soybean varieties such as Burangrang, Anjasmoro and Argomulyo, imposed on waterlogging at vegetative stage (V5) along with the application of GA3 and Salicylic acid. Waterlogging was conducted for 72 h by sinking the planting media inside a pool filled with water. Number of leaves, pod, seed and chlorophyll content were measured. The result showed that foliar application of GA3 (200 ppm) together with Salicylic acid (150ppm) for each enhanced the number of pod and seed for Burangrang soybean variety on waterlogged condition compared with normal condition. Burangrang and Anjasmoro soybean varieties gave the highest chlorophyll content on waterlogged condition after being applied by the same dose of plant growth regulators. In term of yield (number of pod and seed per plant), Burangrang soybean variety is the most promising variety to plant in waterlogged condition.
