SEED RATE: START AT 5 LB./AC. AND TWEAK FROM THERE

For growers who want to keep things simple, a standard seeding rate of 5 lb./ac. should meet the basic needs of stand establishment — as long as for a good stand are followed.

Growers who want a seeding rate that establishes 7 to 10 plants per square foot — 4 plants is about the minimum but you should add a few extra plants for a safety cushion — will want to adjust the seeding rate based on seeding date (cool soils may require a higher seeding rate given the likelihood of higher seeding mortality) and thousand seed weight.
