Basal 3, 5, or 7 fruiting branches of cotton plants were removed at squaring stage to compare their effects on yield and disease control. Fourty days after treatment, the per plant numbers of fruiting branches in the 3 treatments were 13.09, 11.45 and 10.37, respectively, while those of the check plants averaged 14.95. However, the highest lint yield appeared in the treatment with 3 fruiting branches removed. In a set of experiments with the removal of basal 3 fruiting branches conducted at 5 locations of Jiangsu Province in 1988, counted 42 days after treatment, the number of fruiting nodes of the treated plants was similar to that of the untreated; the square and young boll shedding was decreased by 5.28%; the boll number per plant was increased. In addition, the fiber quality and output value were increased
