Abstract

Application of fertilizer on sweetpotato can boost the growth and yield of sweetpotato. This study was conducted to: (1) evaluate the growth and yield response of sweetpotato to the different levels of P and K fertilizers; (2) determine the appropriate levels of P and K fertilizers that will give the optimum yield for sweetpotato; and (3) determine the profitability of sweetpotato production per hectare using solophos and muriate of potash. Application of different levels of solophos and muriate of potash significantly increased the fresh herbage weight, length of the main vines, and leaf area index. NSIC Sp36 applied with fertilizer regardless of the levels showed a significantly longer length of main vines (T2-T6) than the plants not applied with fertilizer (T1). On the other hand, plants applied with 45-55-55 kg ha-1 N, P2O5, K2O (T6) had the highest LAI but were significantly comparable to plants applied with 45-45-20 kg ha-1 N, P2O5, K2O (T4). However, applying different solophos and muriate of potash did not significantly influence the yield and yield component and harvest index of NSIC Sp36 variety. The highest net return of PhP274,039.24 ha-1 was realized when sweetpotato was applied with 45-20-45 N, P2O5, K2O kg ha-1.
