UMTN = number of unmarketable tubers; MTN = number of marketable tubers; TTN = number of total tubers. AWT = average weight of tuber;  = significant at 5% significance levels;  = significant at 1% significance levels; LSD (0.05) = least significant difference at 5% level; CV= coefficient of variation; means in column followed by the same letters are not significantly different at 5% level of significance.
