Field experiment was carried out at the farm of Aida hotel, northern coast, Merci Matroh governorate, Egypt, in order to evaluate the growth and yield of eight Egyptian cotton cultivars (Gossypium banbadense L.) were grown in sandy soil and under drip irrigation system by using treated sewage water which provided from Aida hotel. The experiment design was randomized complete blocks with four replications. Each plot resembled by one bed of 30 m long x 1.45 m width, where cotton planted on both sides of the bed in hills spaced 20 cm and leaving two plants/ hill at thinning time. Sowing date was on March 31, 1992. The cotton cultivars under study were extra – long staple (Giza 45, Giza 70, Giza 76 and Giza 77), besides long staple varieties (Giza 75, Giza 80, Giza 81 and Dandara). The data obtained revealed that the Egyptian cotton cultivars varied greatly with respect to plant growth, yield components and the yield of seed cotton, while lint % and seed index were slightly affected. The highest yield was produced from Giza 80 followed by Giza 45, while the lowest yield was obtained by Giza
76. Generally, the yield of seed cotton was relatively low due to low plant stand at harvest, besides avoiding to use pesticides through the growing season.
