The risk of drought is high in the Sudan savannah zone of West and Central Africa because rainfall in this area is unpredictable in quantity and distribution. Thus, improved maize genotypes tolerant to drought could stabilize maize grain yield in this zone, where recurrent drought threatens grain...

A researcher-managed on-farm experiment was conducted on a soil with low 1.90 mg/kg available phosphorus (P) to evaluate nutrient carryover from soybean grown under different P management options and productivity of maize grown in rotation. Promiscuously nodulating 110-day maturing soybean variet...

Iron deficiency is estimated to affect over one-half the world population. Improving the nutritional quality of staple food crops through breeding for high bioavailable iron represents a sustainable and cost effective approach to alleviating iron malnutrition. Forty-nine late maturing tropical el...

Maize streak virus (MSV) was first studied by Storey in Kenya in the 1920s and resistance transferred into East African maize in the 1960's. Yet the majority of farmers of East Africa are still growing streak-susceptible maize. At the International Institute of Tropical Agriculture (IITA) in Nige...

The attitudes of farmers towards risks influence their decision to invest into farming. Understanding the factors that influence these attitudes is important for crop development. This paper uses a combination of Ridge and Tobit regression analyses to determine the factors influencing risk aversi...

Field experiments were conducted with IITA maize (Zea mays L.) composite B at six locations ranging from forest to savannah in the Western State of Nigeria to assess the level of zinc response on sandy Inceptisols. Zinc, as Na2 Zn EDTA, was applied as broadcast application at 0, 1.0, 2.0, 4.0, an...

Maize (Zea mays) and itch grass (Rottboellia cochinchinensis) plants exhibiting a mild mosaic or mottle were collected from a farmer's field near Mokwa, Nigeria, in 1993. Icosahedral virions (approximately 28 to 30 nm) were purified from symptomatic tissue by differential centrifugation in 0.1 M ...

The effect of constant and fluctuating soil temperature and two soil moisture regimes on the growth, development, transpiration and nutrient uptake by maize seedlings was studied in a greenhouse investigation. The constant root temperatures were maintained at 30, 34, 35, 36, 37, and 38°C for both...

Weed seed bank size and composition were analysed in 1995 and 1996 in maize fields mulched with pruning from Gliricidia sepium, Leucaena leucocephala, and Senna siamea in South Western Nigeria. Plots mulched with pruning from the three trees had a lower weed seed bank in the first year of croppin...
