Polyethylene glycol (PEG), a non-ionic, non-toxic, and non-metabolic polymer, and is hard to be broken down by microorganisms. This compound is therefore can be used to induce drought stress to the cultivated plants.The current data were the first published data from three consecutive years of study with the aims to test the adaptabilitylevel of seven soybean varietiesand find out the two most adaptive varieties before the next step of this three year-based-research. The study applied an experimental study with different concentrations of PEG i.e.: 0%, 10%, 20% and 30% (w.v-1) PEG. There were two different phases of study namely test of viability and test of growing ability on the field. The viability test showed that Deja 1 and Depak Kuning were the two most viable varieties in comparison with those three others Dega, Dena 1, Detap 1, and Anjasmoro. Of the physiological characters, those two most viable varieties showed also the best sensitivity index between medium to tolerant. The Tukey test revealed that the treatment of PEG gave a significant effect on the plant’s growth as well as yield, although the PEG did not cause significant effect on the chlorophyll content, total chlorophyll and carotene. In terms of proline content, it showed that the PEG reveal that the Anjasmoro variety increased the proline content sharply.
