Response of fruiting characteristics and yield of normal-, okra-, and super-okra-leaf types of cotton (cultivar Stoneville 213) to the plant bioregulator 2-diethylardinoethyl-3,4-dichlorophenylether (DCPTA) was examined at two locations in Louisiana. Although DCPTA application did result in increases in the number of blooms in the super-okra-leaf type and increases in total mature bolls in the okra-leaf type, there were no positive effects on yield in any leaf type grown at any of three plant populations examined at either location.
