Effects of conservation tillage on water supply and rainfed maize production in semiarid zones of west-central Mexico
This study analyzes the potential of conservation tillage (CT) for improving maize productivity under a range of soil and rainfall conditions in a semiarid zone of West-Central Mexico, evaluating the consequences of tillage ...
Breeding and selection for drought resistance in tropical maize
Throughout the lowland wet tropics, periodic nonprotracted drought caused by irregular rainfall distribution is responsible for sizable reductions in maize yield. This is particularly true when reduced water availability ...
CIMMYT 1997/98 world maize facts and trends -- Maize production in drought-stressed environments: Technical options and research resource allocation
This publication, through its focus on maize production in drought stressed areas of developing countries, explores economic, research, and policy issues related to maize agriculture in marginal areas of the developing ...
Selection for drought tolerance increases maize yields across a range of nitrogen levels
It is not known whether selection for improved tolerance to a specific abiotic stress leads to correlated changes in performance under other stresses. Drought and N deficiency are important constraints to production in the ...
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 ...
Developing drought and low-nitrogen tolerant maize : proceedings of a symposium
Proceedings of a symposium hosted at CIMMYT in 1996, this publication describes the incidence and intensity of drought and low nitrogen conditions for maize in the tropics, the physiology of drought tolerance and the ...
