Breeding for drought and nitrogen stress tolerance in maize: from theory to practice
Targeted initially for maize breeders in sub-Saharan Africa, the content is based on a successful approach developed at CIMMYT for improving the tolerance of maize to drought and low nitrogen stress. Intended as a supplement ...
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 ...
Evaluating spatial within plot crop variability for different management practices with an optical sensor?
It is essential to have an indication of the sustainability of an agricultural system in addition to the potential, immediate benefits well before the catastrophic consequences of non-sustainability become apparent. Long-term ...
Quantitative trait loci mapping for adult-plant resistance to powdery mildew in bread wheat
(American Phytopathological Society, 2006)
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a major disease to wheat (Triticum aestivum) worldwide. Use of adult-plant resistance (APR) is an effective method to develop wheat cultivars with durable ...
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: ...
The natural abundance of 13C with different agricultural management by NIRS with fibre optic probe technology
In the present study the natural abundance of 13C is quantified in agricultural soils in Mexico which have been submitted to different agronomic practices, zero and conventional tillage, retention of crop residues (with ...
