  • Estimate only. Actual results depend on variety, soil, water, weather and management.
  • Field counts vary a lot across a field — sample at least 5 spots and use the averages.

Results are estimates for planning. Actual figures depend on local conditions, prices and quotes — verify before making decisions.

About this calculator

Count a few plants or a small area in several places, enter the averages, and the calculator scales it up to maunds per acre.

Formula

kg/acre = Plants per acre × Bolls per plant × Boll weight (g) ÷ 1000 × (1 − losses)

Boll weight is the seed cotton in one boll, usually 2.5–4 g.

Examples

  • Default field counts, 1 acre

    Estimated seed cotton (phutti) yield: 23.6 maund per acre (945 kg/acre)

How to take field counts

  • Walk the field in a W or zig-zag pattern and stop at 5–10 spots.
  • Avoid field edges, water-logged patches and unusually good or bad spots.
  • Average your counts before entering them.

Important information

  • Count bolls on 10 consecutive plants at several spots.
  • Include green bolls only if they are likely to open before the season ends.
  • All outputs are estimates for planning. Real results depend on variety, sowing date, soil, water, weather, pests and management.

Frequently asked questions

What is a good cotton yield per acre in Pakistan?

20–30 maund of phutti per acre is good; national averages are lower due to pests and heat stress.

How many cotton plants per acre?

Commonly 14,000–23,000 plants per acre depending on row and plant spacing.

How accurate is a pre-harvest yield estimate?

With careful sampling it is usually within 10–20% of the final yield. Accuracy improves with more sampling spots.
