Water-saturated soil conditions or waterlogging conditions can cause a decrease in soybean productivity. Efforts to destroy crop loss due to inundation through cultivation techniques are considered acceptable so that need for good management in soybean cultivation. This study aims to expression at the productivity results of the three varieties namely Deja-1, Dering, and Anjasmoro with the inundation stress in the vegetative phases V 4 and generative R 1 phases with the use of Gibberellic acid (GA 3 ) and Salicylic acid (SA). The submergence time is given for 72 h in the stated phase. The use of GA 3 and Salicylic acid was given with 3 levels of concentration treatment namely GA 3 (150 ppm) + salicylic acid (100 ppm), GA 3 (200 ppm) + salicylic acid (150 ppm), and GA 3 (250 ppm) + salicylic acid (200 ppm). The outcomes showed the application of GA 3 and salicylic acid showed good production in the number of pods, number of seeds, and weight of seeds. However, the pressure of waterlogging affects the duration of flowering time so that it can cause loss of production.
