Reduced nitrogen and improved farm income for irrigated spring wheat in the Yaqui Valley, Mexico, using sensor based nitrogen management
Wheat nitrogen-use efficiency in the Yaqui Valley has been estimated at about 0.31. The nitrogen that is not recovered by the crop has important environmental costs that have regional and global consequences. In addition, ...
Remote sensing assessment of regional yield losses due to sub-optimal planting dates and fallow period weed management
New tools in agricultural research are needed for improved assessment of agronomic practices and their impacts on crop production. Remote sensing data acquired by satellite sensors offers great promise to complement ...
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 ...
Wheat genetic resources enhancement by the International Maize and Wheat Improvement Center (CIMMYT)
The International Maize and Wheat Improvement Center (CIMMYT) acts as a catalyst and leader in a global maize and wheat innovation network that serves the poor in the developing world. Drawing on strong science and effective ...
