This experiment was conducted to select an optimum application rate of supplemented biochar pellet as slow release fertilizer during tomato cultivation. The supplemented biochar pellet was made through pellet mill placed with a combination (4:6) of biochar and pig manure compost with spraying the N-P-K solution. The treatments consisted of control as the recommended application rates of fertilizers and pig manure compost, N 40%, N 50% and N 70% of the supplemented biochar pellet application based on the recommended application rates of nitrogen. The highest nitrogen balance was 80.1% in the N 40%, while the highest carbon balance was 80.8% in the N 50% during tomato cultivation. Mehlich III extractable P₂O₅ contents in the N 50% was highest among the supplemented biochar pellet treatments. The highest stem diameter and plant height were 10.7 ㎜ and 169.3 ㎝ in the N 70% at 90 days after transplanting. The fresh weight of fruit was not significantly different between the control and N 50% treatment. Therefore, it might be considered that an optimum application rate was N 50% with considering chemical properties of soil and growth responses to application of supplemented biochar pellet during tomato cultivation.
