Farm calculators that answer the bag, the seed and the price
Fertilizer quantities, seed rate, yield and MSP income — four calculators built for the field, with the official grade and price tables shown.

Open calculatorWhat this vertical covers
A farming decision usually comes down to three quantities: how many bags of fertilizer, how much seed, and what the crop will fetch. Official recommendations are written in kg of nutrient or kg per hectare, while the shop sells bags and the mandi buys quintals. These calculators do the conversions with the working shown.
Fertilizer grades and MSP rates are official rules, so they come from the Fertilizer Control Order and the CCEA announcements with the source linked. Yield, cost of cultivation and the actual price you get are yours to enter — the defaults are clearly labelled examples, not a promise for your field.

Worth knowing before you calculate
DAP already contains 18% nitrogen
Working out urea from the full N dose without crediting DAP's nitrogen over-applies N. The fertilizer calculator subtracts it automatically.
Seed rate is per acre, adjusted for germination
Wheat at 100 kg/ha is about 40.5 kg/acre. A lot with 80% germination needs 1.25 times the base seed to get the same plant stand.
MSP is a support price, not a guarantee
MSP for marketing season 2026-27 ranges from ₹2,410 for maize to ₹8,780 for moong per quintal. Procurement at that price depends on crop and state.
