Osmotic stress affects water availability, which can significantly impact seed germination and seedling growth. Polyethylene glycol (PEG) creates negative water potential on the outside of the seed, thereby impeding the ingress of water into the seed and impeding the initiation of germination. High concentrations can seriously impede seedling growth, leading to stunting and even necrosis. This investigation aimed to examine the impact of different PEG concentrations, specifically 0%, 10%, 15%, 20%, 25%, and 30% with three replications on both the germination rate and root length in soybean. The germination rate and root length were assessed every day over a period of six days. The control group showed a germination rate of 100.00%, while the groups exposed to a 10% PEG concentration displayed germination rates ranging from 90.00% to 100.00%. In contrast, experimental groups with high PEG concentration shows reduced rates of germination whereas zero germination were occurred in the groups with 25% and 30% PEG concentrations. In addition, the roots length also exhibited a decline as the concentrations of PEG increased. The results of this study emphasize the negative effects of increased PEG concentrations on both the germination process and root length in soybean plants.
