Effect of Removing Early Developed Buds on Growth, Yield and Quality of Two Cotton Cultivars (Gossypium barbadense L.)


Abstract in English

A field experiment was conducted for two consecutive seasons 2006 – 2007 and 2007 – 2008 to investigate the effect of removing early developed buds on growth, yield and some lint proprieties. Treatments involved in the experiment included three levels of bud removal (0%, 50%, and 100%) at three times (one, two and three weeks after budding). The treatments were arranged in FRCBD, with three replications. Growth parameters (plant height, number of nodes/plant, number of leaves/plant, and number of branches/plant) cotton seed yield, lint yield and lint properties were investigated. The results revealed that bud removal significantly increased plant height, number of nodes, cotton seed yield and lint yield, uniformity (UR) and lint strength (HVI). Also the results showed that, time of bud removal significantly affected growth parameters, cotton seed yield and lint cotton. The results indicated that, varieties and time of bud removal interaction had a significant affect on growth parameters. While, percentage of bud removal and time of bud removal interaction had a significant effect only on cotton seed yield and strength of lint. The results showed that, there were significant difference between cultivars in plant height and number of branches per plant, with cultivar Barakat – 90 the best.
