Other claims from this paper (13)
- Association Environment interactions with nitrogen rate, fungicide, and cultivar were significant for grain yield, leaf rust ratings, and test weight.
- Association Grain yield response to nitrogen rate was linear in five environments.
- Association Grain yield response to nitrogen rate was quadratic in five environments.
- Association There was little evidence of an N by fungicide interaction for grain yield.
- Association Increasing nitrogen rates increased leaf rust severity.
- Intervention effect Fungicide increased grain yield in four of twelve environments.
- Association Cultivar and fungicide interacted significantly for grain yield.
- Association Yield gains from foliar fungicides were related to leaf rust severity and cultivar resistance.
- Intervention effect Nitrogen increased test weight in three environments.
- Intervention effect Nitrogen decreased test weight in two environments.
- Intervention effect Fungicide application increased test weight.
- Observation Test weight varied among cultivars.
- Recommendation The authors caution that higher nitrogen rates may increase yield in some years but also disease pressure and fungicide need.
