| Abstract | ||
| Two field trials were conducted at Sakha Agricultural Research Station during the two successive growing seasons 2004 and 2005 to study the impact of three methods of surface irrigation which are: 1 Short furrows, 2- Long furrows and 3- border irrigation, also during present work three land leveling practices were used as, traditional dead level (precision leveling) and ground surface slope of 10 cms/100 m (0.1% slope) on Egyptian cotton (Gossypium branadeneseL.), variety Giza 86, and irrigation performances. The experimental design which used in this study was split plot with four replicates, where the main plots were assigned to surface irrigation methods and the sub plot were devoted to land leveling methods. Results revealed that, the short furrows irrigation combined with 0.1% ground surface slope significantly affected the seed cotton yield, and all growth parameters. Data also revealed that 0.1% ground surface slope and dead level received the less amounts of irrigation water in the two studied seasons. Also, water application efficiency increased under short furrows irrigation and 0.1% ground surface slope. Compared to long furows and border irrigation. The data showed that the highest values of crop and field water use efficiencies were achieved with short furrows irrigation and 0.1% ground surface slope. | ||
