Title: Preliminary study of potassium fertilizer's effect on sweet potato yield
Abstract: The effect of potassium fertilizer on sweet potato yield was studied through using an orthogonal design with two factors in three levels. The result indicated that in all three plant formulas, the sequence of fertilizer effect was: NPKNKNP. According to the result, we recommend that in sweet potato cultivation, it is better to integrate nitrogen fertilizer with potassium and phosphorus.
