Abstract:
An experiment was conducted with three concentrations of Ethrel (150, 300 and 450 ppm) and three concentrations of CCC (250, 500 and 1000 ppm) to study the effect of the two growth, yield and quality of a sweet potato variety Bhalrakalichola. Three foliar sprayings were given at an interval of 15 days starting from the 30th day after planting. Ethrel as well as CCC showed similarity in influencing the length of vine, number of branches, length of internode, girth of internode and leaf area. While the length of vine , length of internode and individual leaf area were significantly decreased the number of branches and girth of internode were significantly increased by the application of the growth regulators, Ethrel significantly reduced the fresh weight of top and the number of leaves. The weight of tops was not significantly affected by CCC.
