摘要: An experiment to study the effect of different irrigation levels on yield and radiation use efficiency cotton (Gossypium hirsutum) under two sowing methods was conducted at agronomic reaearch area, University Agriculture Faisalabad. The treatment were consist (A) viz (i) flat (ii) ridge (B) six viz: during vegetative growth (1irrigation: missing last 5 irrigations), (missing irrigation), from flowering till maturity (5 irrigation; first irrigation, boll formation (3 irrigations; 3 all stages (Normal 6 irrigation). laid out according RCBD in split plot arrangement with three replications net size 2.25x6 m. 16 (irrigation stages) produced maximum (2406 kqha') seed yield, which significantly higher than treatments. In 14 maturity) (2217kgha'1) 13 up 2098 kqha'. 15 (1362kg ha'). minimum (887kgha'1) recorded 11 growth).
