Oil Crop Seed Rate & Yield Calculators
Pick a crop below to plan seed rate (kg/ha), total seed volume, projected yield, gross revenue and crushable oil output. Defaults are pre-loaded per crop — adjust to your variety, agronomy and market.
How do you plan seed rate and oil output for oil crops?
For sunflower, canola, soybean, sesame, groundnut and other oil crops, seed rate is derived from target plant density, germination, field loss and thousand seed weight; oil output is expected yield multiplied by the crop's oil content.
- Seed rate (kg/ha) = seeds/ha × TSW ÷ 1,000,000, adjusted for germination and field loss.
- Oil output (t/ha) = yield (t/ha) × oil content (%), typically 18–50% by crop.
- Sunflower is normally drilled at 55,000–70,000 plants/ha on 70 cm rows.
- Gross revenue = yield × area × market price per tonne, before crushing margin.
