A field experiment in 2004 and 2005 was conducted at Cotton Research Institute of Iran (CRI), (54° 16¢ , 36° 51¢, 13.3m above sea level). Water resources can be stretch using Sprinkler Irrigation systems, which are highly efficient when properly designed and managed. Cotton pollen and seed cotton is highly sensitive to water. This study was investigated the effect of Sprinkler irrigation programs on Okra-leaf Cotton quality. Four different Irrigation treatments with three replication on Randomized Complete Block were studied. The amount of water used was based on class-A pan evaporation: 100% (T1), 70% (T2), 40% (T3) of cumulative class-A pan evaporation and No Irrigation or rain field (T4). Each plot size was 144m2 with 6m spacing and Si-okra variety-was planted at 80*20 Cm spacing. The plants were harvested by hand twice. Seed cotton was collected at harvest time, processed at the research gin and sent to the Fiber Technology Laboratory of Iran for fiber evaluation. There were significant different between Irrigation treatment and Earliness, Fiber length and Micronaire. The T4 had Maximum Water Use Efficiency (WUE=11Kg/ha.mm) and earliness (92%) but minimum Fiber length (28.9mm). The T2 had maximum fiber length (31.1mm), Strength value (30.5gr/tex), Elasticity (7.0%) and moderate WUE(9.1%) and total yield (3181Kg/ha).
