SCP= stand count percent; UMTY = yield of unmarketable tuber; MTY = yield of marketable tuber; TTY = total tuber yield;  = 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.
