Field trials were conducted in 1999 and 2000 in the northern Guinea savanna of Nigeria to evaluate the potential of several weed management practices to reduce early weed competition in maize. The treatments were different combinations of the herbicide mixture metolachlor + atrazine at 5 L ha−1, ...

Striga hermonthica (Del.) Benth parasitizes maize (Zea mays L.) in sub-Saharan Africa, causing yield losses of up to 100% under severe infestation. Hybrid maize breeding for polygenic resistance to Striga has been undertaken at the International Institute of Tropical Agriculture (IITA) since the ...

North Carolina Design I (NCD I) progenies derived from Pool 16 DT, a white, dent, early maturing, drought-tolerant and streak resistant tropical maize (Zea mays L.) population, were evaluated in the 1995/96 and 1997/98 dry seasons, using two sites each season in Côte d'Ivoire. In all sites, the c...

A study was conducted in the humid-forest, forest-savanna, and Guinea savanna zones of West Africa from 1993 to 1999 to examine the effect of managing crop residues from cereal-legume cropping systems for mulch and fodder for sheeIncreasing the proportion of total crop residues produced from a un...

The selection response of a complex maize population improved primarily for quantitative disease resistance to northern leaf blight (NLB) and secondarily for common rust resistance and agronomic phenotypes was investigated at the molecular genetic level. A tiered marker analysis with 151 simple s...

Participatory research and development approaches involving all stakeholders along the value chain have recently been hypothesized to produce quicker outcomes than the linear technology transfer model. This paper analyzed the crop yield obtained by farmers and their uptake of improved technologie...

The nutrient composition and safety of complementary foods have recently become areas of concern, especially with regard to aflatoxin contamination which has been found to adversely affect health outcomes. This study presents the nutrient and aflatoxin contents of complementary foods consumed by ...

Balancing the nitrogen (N) budgets of agricultural systems is essential for sustaining yields at lower environmental costs. However, it is still rare to find reports on the total N budgets of agricultural systems including all N fluxes in the literature. Here, we conducted a comprehensive study o...
