Abstract

                                The effect of ethrel and cycocel each at three concentrations on the yield component of cassava varieties reveals that the total number of roots per plant was significantly influenced by CCC 5000 ppm and the same was more pronounced at the peak bulking phase. Among the varieties. Co.l recorded a greater number of roots. The number of tuberous roots was more under the treatment ethrel 250 ppm and the variety Co.1 had the highest root number. The yield of tubers was significantly influenced by CCC, 10,000 ppm and the variety Co.1 recorded the highest yield.

Key words : Total number of roots, peak bulking, tuberous roots, yield components
