Study on effect of plant growth regulators on vegetative growth of summer okra (Abelmoschus esculentus L. Moench) Var. Varsha Uphar
Year: 2018
Type: article
Abstract: Growth and fruiting pattern of okra (Abelmoschus esculentus L. Moench) CV. Varsha Uphar as affected by the growth regulators cycocel (CCC), paclobutrazol (PBZ) and ethrel were evaluated in field studies. High temperature and high humidity resulting more vegetative growth as compare to reproductive growth. Growth retardant suppresses the vegetative growth and promotes reproductive traits. Therefore, different concentrations of CCC (200, 400 & 600 ppm), PBZ (150, 250 & 300 ppm) and ethrel (150, 250 & 300 ppm) were sprayed on okra plants at 30 DAS stage, to ascertain their impact on plant growth. Observations were recorded on various traits and concluded that the lowest plant height, internodal length, highest number of leaves, leaf area, and petiole length of leaves per plant were recorded most in CCC @ 600 ppm while maximum number of nodes, lowest absolute growth rate (AGR) and relative growth rate (RGR) of plant, fruit length and ascorbic acid were higher in ethrel @ 300 ppm.
