The reported study summarizes the outcome of field trials on irrigation techniques for cotton crop carried out during Kharif season of 1990 at Pakpattan and 6R-Hakra sub-projects under the Command Water Management Project. The trials mainly comprised testing of irrigation techniques such as border, Furrow-ridge and Furrow-bed methods of irrigation on farmer's to develop and demonstrate methodology that can allow the farmers to their water resources more efficiently. Efficient use of irrigation water not only saves available water supplies but also have a direct impact on alleviating logging and salinity. Except at one location the trials concluded a saving of irrigation waterlogging 25 to 53 percent incase of furrow-bed and 24 to 33 percent under furrow-ridge irrigation as compared to the water applied under flat border irrigation method. The cotton yield improved by 6 to 52 percent at 6R-Hakra but decreased by 2 to 10 percent at Pakpattan sub-project. Saving of water accompanied by improvement in yield is a break through for the farmers having constrained water availability particularly on salt affected soils. The salt movement through the beds improved the soil-plant environments for better plant growth.
