Other claims from this paper (7)
- Intervention effect In malting barley, net photosynthetic rate of the penultimate leaf, leaf area index and light extinction coefficient increased as the topdressed nitrogen fraction rose from 0% to 30% and then decreased from 30% to 50%.
- Intervention effect Putative gross maximum canopy photosynthesis of malting barley was highest at a topdressed nitrogen fraction of 30%.
- Intervention effect Remobilization of pre-anthesis stored assimilates from vegetative organs into grains was hardly significantly affected by the fraction of topdressed nitrogen.
- Intervention effect Grain yield of malting barley was highest at a topdressed nitrogen fraction of 30%.
- Intervention effect Plant nitrogen uptake and physiological and agronomic nitrogen use efficiencies in malting barley were highest at a topdressed nitrogen fraction of 30%.
- Association The enhanced nitrogen use efficiency corresponded to improved photosynthetic nitrogen-use efficiency in leaves at a topdressed nitrogen fraction of 30%.
- Recommendation The authors conclude that an appropriate fraction of topdressed nitrogen improved assimilation rate and nitrogen use efficiency, giving higher grain yields and proper grain protein content in malting barley.
