Title
Crop Nitrogen Demand and Grain Protein Concentration of Spring and Winter Wheat
D. B. Fowler Agronomy Journal 2003. doi:10.2134/agronj2003.0260
Other claims from this paper (9)
- Association Large grain protein concentration responses to added N were accompanied by large increases in grain yield.
- Association Genotype influenced the upper limit of yield when N was not limiting.
- Association Environment influenced the upper limit of yield when N was not limiting.
- Association The relationship between GPC and grain yield depended on the part of the N fertilizer response curve sampled.
- Association Across cultivars there was a strong negative correlation between GPC and maximum potential grain yield.
- Association GPC at the point of maximum grain yield increased as the potential grain yield of a cultivar was reduced by environmental limitations.
- Association Growing season weather had a large influence on GPC–grain yield relationships.
- Recommendation The critical GPC–grain yield responses must be known for each cultivar before GPC can be used as a practical postharvest indicator of N sufficiency.
- Recommendation GPC may be a useful postharvest indicator of N deficiencies for crops under N stress, with caution in managing N fertilizer use.
