Two cotton cultivars having different plant morphology were evaluated for seed cotton yield and some economic characters keeping 1,2 and 3 plants per dibble at a standard plant configuration of 75 x 30 cms. The results showed that the cultivars do not differ significantly form each other in yield of seed cotton, boll weight, ginning out turn and staple length except number of bolls per plant. In spite of difference in plant shape, CIM-85 and MNH-93 produced maximum yield of seed cotton at two plants and one plant per dibble respectively. The increase in number of plants per dibble showed statistically significant negative effect on bolls per plant boll weight and lint percentage. However, the staple length was not affected by different number of plants per dibble. The varieties and number of plants per dibble inter-action effects remained significant only for seed cotton yield.
