The study was carried out in the Sultantepe village of Eyyübiye district of Şanlıurfa province in the 2020-2021 growing seasons according to the randomized blocks of divided plots experimental design with 3 replications. From defoliant applications, Finish Pro 765 (720 g l<sup>-1</sup> Ethephon + 45 g l<sup>-1</sup> Cyclanilide), Genesiss (200 g l<sup>-1</sup> (Carfentrazone-ethyl + 30 g l<sup>-1</sup> Diuron), Ethephon (720 g l<sup>-1</sup>), Son Final (480 g) /l Ethephon+60 g l<sup>-1</sup> Cyclanilide) were applied in normal and late sowing when 60% of the bolls were opened. In the study, ginning outturn (%), 100 seed weight (g), fiber fineness (mic), fiber strength (g tex<sup>-1</sup>), fiber uniformity (%), fiber length (mm), reflectance value (Rd), yellowness (b+) and ratio of trash matter (TrAr %) were determined by examining.<strong>&nbsp; </strong>According to the results obtained from the study, it was observed that the sowing time had a significant effect on the fiber quality, and the defoliant applications had no effect other than the fiber fineness.</p> ER -
