This study was conducted to determine the growth and yield performance of sweet potato cultivars as affected by different sources of fertilizer under Pampanga condition. The study was conducted from August 24, 2021 to November 13, 2021 at La Paz Turu, Arayat, Pampanga. The following agronomic characteristics were determined: length of vines before harvest, number of days in harvest, yield of tuber, diameter of tuber, length tuber, the marketable weight of tuber, non-marketable weight of tuber, yield of tuber per ha, and the cost and return analysis. The study was designed using Two Factorial Randomized Complete Block Design with two blocks and three treatments. Three cultivars were used in the study namely: Inubi as V1, Super Taiwan as V2, and Bureau as V3. Two fertilizers were applied in treatments and one control, F1Recommended Rate, F2Organic Fertilizer and F3 is control/no fertilizer. Length of vines before harvest - there is a significant difference in the length of vines before harvest as affected by different cultivars and sources of fertilizer. In terms of cultivars, the longest vines were obtained from Inubi and Super Taiwan with 195.47 cm and 170.25 : om, respectively. On the effect of fertilizer sources, the recommended rate of.
