Other claims from this paper (11)
- Intervention effect Increasing nitrogen increased grain yield quadratically across cultivars.
- Intervention effect Increasing nitrogen increased kernel weight quadratically across cultivars.
- Observation Hybrid 8644‐27 had the highest grain yield, 5.3 Mg ha −1.
- Observation Hybrid 8644‐27 had the highest kernel weight, 26.62 mg kernel −1.
- Observation Mean grain protein yield per area did not differ significantly among cultivars in either year.
- Observation At 30–60 kg N ha −1, 8644‐27 and TZPB‐SR had more floaters than other cultivars.
- Observation SPL and TZB‐SR had relatively few floaters at 30–60 kg N ha −1.
- Observation SPL and TZB‐SR had high test weights, over 811 kg m −3 in 1993.
- Observation SPL and TZB‐SR had high test weights, over 778 kg m −3 in 1994.
- Recommendation The authors suggest 8644‐27 and TZPB‐SR for traditional dry milling.
- Recommendation The authors suggest SPL and TZB‐SR for industrial dry milling and grits.
