ABSTRACT
There is now a fastly expanding application of drip irrigation line on extensive linear crops such as cotton. This system is undergoing a strict quality controlled in all procedure in all phases of production. There were no significant differences in yield and fiber quality between drip irrigation system in sandy soils of the new land and tradional cultivation in the Nile Valley. The highest yield of seed cotton per ha was achieved by Giza 80, being 2151 lbs/ha. Giza 45 cultivar was increased by 63.31% of seed cotton yield and 13.50% of fiber maturity in drip irrigation system. This system maintaine on the level of the fiber quality of the commercial cultivars.
