This paper examines the economic viability of biochar application in crop production, focusing on varying application rates of 0, 4, 8, 12, 16, 20, 24, and 28 tons per hectare. Biochar, produced through biomass pyrolysis, has shown promise in improving crop yields and contributing to environmental sustainability. The biochar production financial metrics were analyzed, and it shows that the economic parameters such as Operational Expenditure (OPEX) amounting to $2339.40, feedstock cost of $2420.25, and transport cost of $293.71. The total biochar production cost was $232.87 per ton, with labour costs comprising 27.07 % of the overall production and application expenses. The analysis revealed that the maximum annual revenue from crop production (peas in the rabi season and maize in the kharif season) reached $525.88 per hectare at a biochar application rate of 12 tons/ha. Carbon sequestration revenue was estimated at $186.6 per ton of biochar. Economic indicators revealed that the benefit-cost ratio (BCR) was the highest at 1.476, with an 8 ton/ha biochar application rate. At the same time, the net present worth (NPW) and internal rate of return (IRR) also maximized at this rate, reaching $932.85 and 85.71 %, respectively. Conversely, higher biochar application rates of 24 and 28 tons/ha resulted in negative NPW and IRR values and BCR values below 1, indicating economic infeasibility at these levels. These findings highlight the economic viability and potential agronomic benefits of biochar application at optimal rates of 8 tons/ha for promoting sustainable crop production.
