Seed weights & sowing rates
Sowing rates for individual situations vary. The following are general guidelines.
Seed weights and sowing rates (kg/ha) for bare seed
n/r = not normally recommended
*Seed weights vary a little between cultivars, & even between seed lines of the same cultivar
1. Bromes and short term ryegrass produce awned seed. Awns can be shortened or removed during seed cleaning, enabling the seed to flow more freely through the drill.
Seed treatment
Seed treatment can affect seed weight and sowing rate. There are two main types of seed treatment - a film coating (e.g. Agricote Grass) which has little effect on seed weight or sowing rate; and a lime-based seed coating (e.g. Agricote Clover) that has a significant weight build up and increases seed weight and sowing rates (see Seed treatment comparison for more.)
