A field investigation was conducted at College of Agriculture, CAU, Imphal, Manipur, India during session 2019-20. Nitrogen and potassium are limiting factors when it comes to influence on growth, yield and quality of sweet potato cultivation. The study consisted of 16 treatment combinations with 4 levels of N (0, 35, 50 and 65 kg/ha of N respectively) and 4 levels of K (0, 35, 50, 65 kg/ha of K respectively) with 3 replications in FRBD on variety NFSP-1. The findings of the experiment are as follows. Pertaining to growth and yield, highest level of N i.e., 65 kg/ha (N3) and highest level of K i.e., 65 kg/ha (K3) gave highest values. N3 and K3 also gave better values for quality characters like DM, TSS, starch, sugar, crude protein, ash and NPK content of tubers. N x K interactions did not show any significant differences between the treatments for the aforementioned characters. A combination of 65 kg/ha of N and 50 kg/ha of K (N3 x K2) gave highest B: C ratio of 3.33.
