This study was performed with three main objectives. First, to increase the yield potentially of different varieties of okra and their response to different growth regulators when used as foliar spary; second, to find out the most effective growth regulators i. e. ethrel or NAA and its concentration, and third, to investigate the effect of growth regulators on various physiological parameters and other growth/yield attributes.enPLANT PHYSIOLOGY AND ECOLOGY, AGRICULTUREA STUDYThesis
