GROWTH AND YIELD RESPONSE OF SWEET POTATO VARIETIES IN SUDAN SAVANNAH ZONE OF MAIDUGURI, BORNO, STATE

The aim of the study is to determine the performance of four varieties of sweet potato (Ipomoea

per plant and tuber weight per plant. The data analysis was subjected to the Analysis of Variance
and treatment means were found to be significant were separated using the Duncan’s Multiple
Range Test (DMRT) at 5% level of significant. The result revealed that there was a significant
