EFFECTS OF PHYTOHORMONE ON GROWTH-DEVELOPMENT AND YIELD OF OKRA (ABELMOSCHUS-ESCULENTUS (L) MOENCH)

In order to find out the effect of foliar applications of different co ncentrations of cycocel (CCC), indole butyric acid (IBA) and gibberell ic acid (Ga3) on okra and to determine suitable concentration level fo r obtaining higher yield, a pot culture experiment was conducted. Plan t height, length and weight of fruits were reduced in all concentratio ns of CCC and IBA treatment whereas these characters were positively i nfluenced at all concentrations of GA3 applications. More number of le aves and branches/plant were obtained with CCC treatments, particularl y with that of 500 ppm over all levels of IBA and GA3 treatments. 500 ppm CCC and 20 ppm GA3 gave significantly higher number of fruits and yield/plant. However, CCC at 250 ppm and GA3 at 10 and 50 ppm produced increased yield/plant with insignificant variation over control. Appl ication of CCC at 1000 ppm decreased fruit number and yield/plant as c ompared to control and its other concentration.
