ICAR-DMR's Hindi farmer folders print a cost of production of about Rs 20 to 25 per kg for seasonal white button and Rs 10 to 15 per kg for oyster. Those folders are undated and carry early 2010s prices.
Historical figures do not establish current costs or the relative profitability of different crops. Use current quotations and measured local performance; do not submit historical prices as a current bank estimate.
