Abstract: 
A two factor pots experiment was conducted during winter season of 2018/2019 investigate effects of two growth regulator and soaking time on germination indices and seedling vigor of Pigeon pea seeds. The experiment was laid out according RCBD with three replications. Parameters studied include germination indices; Final germination percentage FGP, Mean daily germination MDG, Daily germination speed DGS and vigor index. Also, seedling dry weight, length and root length were measured. The results indicated that soaking seeds of pigeon pea enhanced germination behaviors and seedling characters. Application of GA or lemon at medium level concentration increased all characters measured in this study particularly under longer time of soaking. The positive effected of soaking with water with combination of GA significantly increased germination indices and seedlings growth characters. In conclusion, as a result, soaking seeds of pigeon pea with application of medium growth regulator concentrations could increase the seed germination indices and seedling growth characters.
