Other claims from this paper (9)
- Association Seedling emergence and second-year survival were closely related to seeding rate.
- Intervention effect The percentage of planted seeds becoming mature plants decreased with higher seeding rate.
- Intervention effect More seedlings emerged from small seeds than medium or large seeds.
- Intervention effect More seedlings emerged from composite seeds than medium or large seeds.
- Intervention effect Seed size did not affect yield in the seeding year or following year.
- Observation At one location 1.1 kg/ha produced maximum following-year yield.
- Observation At a second location 2.2 kg/ha produced maximum following-year yield.
- Recommendation Sizing seed offered no advantage.
- Intervention effect Small seed produced seedling density as good as or better than large seed at the same rate.
