Singh (1991) cited the followingequation to estimate seeding rate: Seeding rate (kg.ha-1) = (10000 × thousand seeds weight×100 ×100)/(1000×1000× purity% × Germination% × spacing (meters). Test weight is theweight of seeds per unit volume and is expressed in kilograms per Hectoliter or pound per bushel.

1. Calculate the seed rate of mung bean for sowing 1 hectare of crop from the following: spacing=30cm×10cm germination %=92% purity %=85% 1000 grain weight =36g Solution: Plant population= 10000 0.3×0.1 =333333.33 Seed rate = 333333.33×36×100×100 92×85×1000×1000 =15.34 kg/ha.
May this helps you.
