Abstract
Significant effect of different irrigation schedules and integrated nutrition levels was determined on fraction of intercepted radiation (Fi) in cotton. The treatments were four irrigation schedules viz. six irrigations (I1), three irrigations (I2), irrigation at 25 mm deficit (I3) and irrigation at 50 mm deficit (I4), and seven integrated nutrition levels i.e. control (N0), 75-37.5–37.5 kg NPK ha-1 (N1), 75-37.5-37.5 kg NPK ha-1 + FYM (farm yard manure) @ 20 t ha-1 (N2), 75-37.5-37.5 kg NPK ha-1 + wheat straw@ 5 t ha-1 (N3)
