Other claims from this paper (13)
- Intervention effect Seedlings in tilled soil had more dry matter, height, and internode length than sod seedlings.
- Observation Node number and plant density declined in some experiments.
- Intervention effect Previous-fall sod tillage increased seedling yields over fresh tillage or sod.
- Intervention effect At a second seeding, spring-tilled sod performed comparably to fall-tilled sod.
- Observation Sod-sown seedlings remained inhibited at the second seeding.
- Observation A water-soluble toxin was detected in field-collected dry sod.
- Intervention effect Conductivity-matched KCl or NaCl did not inhibit alfalfa germination.
- Intervention effect Conductivity-matched NaCl did not inhibit alfalfa germination.
- Intervention effect Ground sod at 5% in soil inhibited seedling yield and leaf area.
- Intervention effect Ground sod at 10% in soil inhibited seedling yield and leaf area.
- Intervention effect Greater watering intensified sod-associated inhibition.
- Observation Sod cores released 8-10 times more ethylene than tilled soil over 12 days.
- Intervention effect Continuous ethylene exposure reduced alfalfa height, yield, and leaf area relative to air.
