The activity was proposed with the objective of determining the combined application rate of inorganic NPSB and N fertilizer that maximizes the yield and yield components of sweet potato. Sweet Potato variety Naspot-13, was used for the experiment. The experiment was arranged in factorial combination of four level of NPSB (0, 50, 100 and 150 kg ha-1) with four level of N2 (0, 23, 46 and 69 kg ha-1) in RCBD with 3 replications. The analysis of variance showed that the combination of 100 kg ha-1 NPSB fertilizer and 69 kg ha-1 of Nitrogen fertilizer gave the highest marketable root yield (553.09 qt ha-1). Therefore, cultivation in the Adola rede and similar areas can be optimized by applying 100 kg ha-1 of NPSB fertilizer and 46 kg ha-1 of nitrogen, resulting in improved plant growth and marketability, higher root yields and cost efficiency.
