Abstract:

 


In this study, the effects of squares (flower-bud) and flowers removal on yield and fiber quality of cotton (Gossypium hirsutum L.) were tested. Field trials were conducted on research field of Harran University Faculty of Agriculture, Department of Field Crops in years of 1998 and 1999, at southeastern of Turkey. Field trials were arranged in completely randomized block design with four replications. The Sayar 314 cotton (Gossypium hirsutum L.) variety was used as plant material. Squares were removed at first two weeks of squaring (SR1-2) and flowers were  removed throughout first to tenth week of flowering with two weeks interval (FR1-2, FR3-4, FR5-6, FR7-8, FR9-10) and check plot. At the end of variance analysis it was indicated that cotton could compensate for generative organs losses at early stage (SR1-2 and FR1-2) despite dramatically yield reduction at mid-flowering losses (FR3-4 and FR5-6, 21.11% and 10.49% in 1998 and 22.05% and 12.28% in 1999, respectively). Late removals (FR7-8 and FR9-10) have not significant effect on yield. Not any fiber quality parameters were affected by removals.
