The experiment was conducted to investigate the effects of different regimes of irrigation schedule on various vegetative and reproductive stages of cotton crop. The results showed that irrigation effect was non significant for number of plants mE-2 , while I 4 treatment produced maximum number of monopodial branches 2.18, but statistically it was at par with I 3 , I 5 . I 4 treatment showed maximum number of sympodial branches (20.43), followed by I 3 (18.63). F.H-900 showed statistically higher sympodial branches (18.34) than the F.H-901 (17.08). Maximum number of flowers per plant was formed in the I 4 treatment (101.00), followed by I 3 (96.31) and I 5 (92.23). Significantly higher number of flowers and boll drops was recorded in treatment I 1, followed by I 2 . Flowers and boll drop per plant decrease with increase in irrigations applied to crop. Minimum number of flowers (60.45) and bolls (16.98) dropped per plant were in I 4 and I 3 (65.0 and 22.72, respectively).
