Site-Specific Nutrient Management: Implementation guidance for policymakers and investors
(GACSA; CIMMYT; ILRI; CCAFS; WRI, 2015)
Site-Specific Nutrient Management (SSNM) provides guidance relevant to the context of farmers’ fields. SSNM maintains or enhances crop yields, while providing savings for farmers through more efficient fertilizer use. By ...
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. ...
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: ...
