The present investigations was carried out to estimate the variations in morphological, pigments variation and ameliorating effect of propiconazole (PCZ) and salicylic acid (SA) on drought stress in sorghum (Sorghum bicolor L. Moench.) Var. CO-30. 30 Days After Sowing (DAS), the plants were subjected to 3, 6 and 9 Days Interval Drought (DID) stress and drought with PCZ at 1mM and drought with SA at 1mM at 30, 40 and 50 DAS. The plant were irrigated regularly alternate day interval was kept as control. The plant samples were collected on 60, 70 and 80 DAS from all the treatments. The morphological variation and photosynthetic pigment estimation was carried out in each treatments. Individual and combined drought stress with PCZ and SA treatments increased the root length when compared to control. Then another morphological and photosynthetic pigment is decreased than compared to control but increased the drought stress plants. The PCZ and SA treatments mitigated are the adverse effect of drought stress by increasing the morphological and pigment contents and there by the way for overcoming drought stress in S. bicolar plants.
