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...

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...

The incorporation of livestock into alley farming systems, in which food or forage crops are grown between hedges of multipurpose trees that are regularly pruned for mulch and/or forage, has been studied for over 10 years in Africa. Prunings from leguminous trees such as Leucaena and gliricidia c...

The paper evaluates the effects of forage type and level of concentrate supplementation on forage intake, diet apparent digestibility, purine excretion and milk production. Twelve crossbred cows (Bos taurus X Bos indicus), in early lactation were allocated to the following six dietary treatments:...

Normalized difference vegetation index (NDVI) is a non-destructive measure of green vegetation growth or above ground biomass of a crop. NDVI may also be used to evaluate traits such as early vigour and stay green which are important for adaptation to drought stress. In the present study, the rel...

Emergence of several seed companies in the West Africa sub-region during the last decade has necessitated intensified efforts towards hybrid development and extensive testing. The objectives of the present study were to evaluate selected Striga-resistant maize (Zea mays L.) hybrids for grain yiel...

Breeding programs for acid-soil tolerance are desirable as a relatively inexpensive and permanent way for increasing maize (Zea mays L.) yield on these soils. Our objective was to compare the genetic effects controlling the expression of maize traits in acid and non-acid soils. Seven related and ...

Researchers worked with farmers in eastern Uganda to develop alternatives for soil management using crotalaria (Crotalaria ochroleuca), mucuna (Mucuna pruriens var. utilis), lablab (Dolichos lablab), and canavalia (Canavalia ensiformis) as green manures in short-term fallows. The participatory re...

The potential of Crotalaria ochroleuca check for this species in other resources as a green manure crop was evaluated in a series of on-station and on-farm trials on reddish kaolinitic loam and sandy clay loam soils in Uganda. Production of the green manure by intercropping Crotalaria with eithe...
