Increasing wheat yields sustainability through agronomic means
This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. ...
Narrowing the agronomic yield gap with improved nitrogen use efficiency: A modeling approach
Improving nitrogen use efficiency (NUE) in the major cereals is critical for more sustainable nitrogen use in high-input agriculture, but our understanding of the potential for NUE improvement is limited by a paucity of ...
Yield uncertainty at the field scale evaluated with multi-year satellite data
The level of yield risk faced by a farmer is an important factor in the design of appropriate management and insurance strategies. The difference between field scale and regional scale yield risk, which can be significant, ...
The effects of urea fertilisation and genotype on yield, nitrogen use efficiency, 15N and 13C in wheat
New methodologies to assess nitrogen use efficiency (NUE) in field crops could help in the characterisation of large numbers of genotypes and growing conditions. The effects of chemical nitrogen fertilisation on yield: ...
Satellite monitoring of yield responses to irrigation practices across thousands of fields
Geographic information systems (GIS) present new opportunities for empirical agronomic research that can complement experimental and modeling approaches. In this study, GIS databases of irrigation practices for more than ...
Adapting wheat cultivars to resource conserving farming practices and human nutritional needs
As farmers increasingly adopt resource conserving farming practices, there is a need for wheat cultivars that better adapt to the changing environment and the nutritional needs of people, particularly those living in ...
