Sweet potato was grown in a sandy loam soil with three levels in each of N and K and two sources of Potash namely, muriate of potash and schoenite. The results indicated that nitrogen application had significantly increased the tuber yield over control but the yield difference between 50 and 100 kg N/ha was not appreciable. Potash levels though did not have any significant effect on the tuber yield, had increased the starch content. Schoenite source of K had similar influence on the vield and starch content of sweet potato tuber as that of muriate of potash.
