Title
Seed Size and Seeding Rate Effects upon Stand Density and Yield of Alfalfa1
C. S. Cooper; R. L. Ditterline; L. E. Welty Agronomy Journal 1979. doi:10.2134/agronj1979.00021962007100010021x
Other claims from this paper (9)
- Association Seedling emergence and second-year survival were closely related to 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.
- Intervention effect Composite seed produced seedling density as good as or better than large seed at the same rate.
