Mandi price at last season's harvest (September–October 2026): about ₹7,446 a quintal across India's mandis.

This week: about ₹7,283 a quintal, the middle of 20 mandis across India (latest 13 Nov). At that price an acre would leave about ₹12,000 a season after typical costs.

Minimum support price: ₹8,343 a quintal (2026-27), if you sell to government procurement.

Prices are usually best in August.

Typical costs are about ₹23,000 an acre (seed, fertiliser, labour and hired machines, from the government's cost survey). They are spent whatever the harvest.
