| Abstract | Soil fertility improvement is an important goal for plant production in order to achieve the intended yield. In particularly, utilizing of farm waste materials is the methodology that could reduce the cost of soil improvement and circulate the production components for sustainability. Therefore, the aim of this research was to investigate the application of compost and biochar as compared to chemical fertilizers for red oak lettuce production. The experiment was conducted in a randomized complete block design (RCBD) replicated four samples with ten treatments. The treatments were consisted of T1: control (not applied compost and biochar), T2-T3: compost at rates of 1,000 and 2,000 kg/rai, T4-T5: biochar at rates of 1,000 and 2,000 kg/rai, T6: compost 1,000 kg/rai and biochar 1,000 kg/rai, T7: compost 1,000 kg/rai and biochar 2,000 kg/rai, T8: compost 2,000 kg/rai and biochar 1,000 kg/rai, T9: compost 2,000 kg/rai and biochar 2,000 kg/rai, and T10: chemical fertilizer at recommended dose. The results revealed that the application of chemical fertilizers at a recommended dose still produced the highest yield across all harvesting cycles and did so at a lower cost than applying compost and biochar at the highest rate. However, it was discovered that applying compost and biochar at a rate of 2,000 kg/rai each could produce the maximum net profit if the produce could be sold for the price of a safe/organic product. |
