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 ...
Straw management, crop rotation, and nitrogen source effect on wheat grain yield and nitrogen use efficiency
Nitrogen fertilizer management from different sources and annual crop rotations are important components of wheat (Triticum aestivum L.) production systems, especially where air and soil quality issues have prompted a ...
