Estimate seed requirement from plant spacing, germination, purity, and thousand-seed weight.

Area

Row Spacing (cm) Plant Spacing (cm) Germination (%) Seed Purity (%) 1000 Seed Weight (g)

Plant population = area in square meter divided by plant geometry (row spacing x plant spacing).

Corrected seeds needed = target population divided by (germination fraction x purity fraction).

Seed quantity (kg) = corrected seeds x (1000 seed weight in g / 1000) / 1000.
