The results declared that Lashatawere superior over Coker-310 variety in number of sympodia branches in plantand number of bolls in plant and boll weight (g) and seed index (g) and seedcotton yield (Kg/h.) were the increasing percentage in seed cotton yield arrived41.78% from Coker-310 variety which noticed were earlier than Lashata varietyand the variation between the two varieties were little and not significant forplant height and number of monopodia branches in plant and lint index and lintpercentage. The distance 40 cm between holes significantly affected plantheight and were superior over the distances 20 and 30 cm in mean number ofbolls in plant which reflect over seed cotton yield mean (Kg/h.) andsignificantly increasing were observed in number of sympodia branches in plantand boll weight when planted in distance 30 cm between holes, the higher plantheight and also higher earliness percentage in yield were recorded when weleave two plants in hole and also noticed significantly increasing in number ofsympodia branches in plant and number of bolls in plant and seed cotton yield atleaving three plants in hole.
