The result showed that tested four soybean varieties (Anjasmoro, Dering 1, Devatra 2 and Grobogan) and the concentrations of PEG 6000 (0% control, 5% 10 %, 15% and 20%) did not interact in affecting the number of flowers and the number of pods. Soybean varieties varied in their tolerance to drought stress at Entisol. Based on all observed both vegetative and generative growth variables, the order of drought tolerance of soybean varieties (from the most to the least tolerant) were Anjasmoro, Dering 1, Devatra 2, and Grobogan. Increasing the concentration of PEG 6000 to the highest one of 20%, constantly reduced the vegetative and generative growths (plant height, number of leaves, number of flowers and number of soybeans pods). The predicted effective dose selection of PEG 6000 for soybean drought tolerant was 19.50%; it reduced yields up to 50%.
