Other claims from this paper (8)
- Observation Seeding forage mixtures at any of four dates between late May and July 15 gave satisfactory results.
- Intervention effect For the timothy, alfalfa, red clover and alsike mixture, yield losses between the fourth and eighth seeding dates were 45, 25 and 15% in the first, second and third harvest years.
- Intervention effect For the bromegrass, alfalfa and ladino clover mixture, yield reductions between the fourth and eighth seeding dates were 75, 25 and 15%.
- Intervention effect Yield loss in the third harvest year was .65 tons of dry matter per acre in each mixture for later seeding.
- Intervention effect Legume establishment and contribution were greatly reduced at later seeding dates.
- Intervention effect Timothy performed somewhat better than bromegrass at later planting dates.
- Intervention effect Timothy and bromegrass responded better than legumes to delayed planting.
- Intervention effect Species composition differences attributable to planting date were practically eliminated by the end of the third harvest year.
