Other claims from this paper (7)
- Intervention effect Seeding rates of 84 and 101 kg ha−1 produced the greatest winter wheat yields compared with 34 kg ha−1.
- Intervention effect The seeding rate of 34 kg ha−1 gave the lowest winter wheat yield.
- Intervention effect Lower than optimum seeding rates reduced winter wheat grain yield.
- Intervention effect Seeding rates above the optimum showed no agronomic penalty.
- Association Seeding rate and variety affected winter wheat grain yield in 11 of 12 environments.
- Association A combination of two or more yield components was a good predictor of wheat yield response to increased seeding rate.
- Recommendation A seeding rate of 67 kg ha−1 or more is an important factor for dryland winter wheat yield in the central Great Plains.
