Secondary traits can improve precision with which drought or low soil nitrogen (low-N) tolerant maize (Zea mays L.) genotypes are identified, compared to measuring only grain yield under each stress. The objective of this study was to identify secondary traits for indirect selection for yield imp...

Maize improvement at the International Institute of Tropical Agriculture (IITA), which began in the 1970s, built on the germplasm and experience of earlier years. The main breeding emphasis was to develop maize cultivars and hybrids with high yield potential and durable resistance to diseases and...

Participatory varietal selection is premised on the basis that only a small percentage of varieties developed by breeders are eventually utilizedbecause farmers are left out of the selection process. Consequently a total of 275 farmers were engaged in the promotion of stem borer resistantmaize va...

A study was conducted at six sites of Kenya Coastal region to evaluate candidate maize genotypes for inclusion in stem borer IPM package for the area. Stem borer infestation/damage during the trial period were rather low but nonetheless, significant differences were observed between the insectici...

The moist savannas of West and Central Africa have great potential for maize grain production due to high levels of radiation and reduced incidence of pests and diseases. However, soils in this zone are generally low in organic matter and cation exchange capacity in addition to land use intensifi...

The major thrust of the West and Central Africa Collaborative Maize Research Network (WECAMAN) has been on the development of early and extra-early maize varieties and associated agronomic practices. Adoption of these varieties and, to some extent, the complementary agronomic practices by farmers...

Maize (Zea mays L.) is cultivated under a broad range of climatic conditions in West and Central Africa (WCA). Unfortunately, maize production is constrained by a host of abiotic and biotic stresses, including drought, low soil fertility, diseases, insect pests, and the parasitic weed Striga herm...

Low soil nitrogen (low-N) level is responsible for yield reduction in maize (Zea mays L.) fields in sub-Saharan Africa. A clear understanding of the genetic diversity among early generation inbred lines selected from various elite low-N- tolerant populations offers an opportunity to obtain lines ...

The Guinea savannas of Nigeria have a high potential for the production of maize because of favourable environmental conditions. Despite this high potential, the yields obtained in farmers' fields are still very low. This is due to soil degradation and nutrient depletion arising from intensificat...
