The agriculture and health program of the International Institute of Tropical Agriculture (IITA), a CGIAR institution in Africa
(2012-07)The agriculture and health program of the International Institute of Tropical Agriculture (IITA) is one of the eight research for development (R4D) programs implemented by IITA in the humid and sub-humid tropics of sub Saharan Africa. The overall goal of this program is to improve diets, health, and productivity through research in micronutrients content, food toxins, nutrient patterns and science-based evidence policy advocacy. This paper explains the rationale of this program, the main objectives, ... -
Les insectes nuisibles du riz au champ en Afrique: biologie et methode de lutte
(1993)Les inseeles nuisibles sont une contrainle principale II la production du riz en Afrique et dans d'autres parties du monde. lis occasionnent toujours des pertes de rendement de rordre de 30 II 100'*. Les mesures de lutle comprennent les methodes culturales el biologiques, la resistance de la plante-hote et les me-thodes chimiques. Les methodes chimiques presentent plusieurs inconvenients. La lutte integree contre les depredateurs combine les avantages de plusieurs me-thodes de lutte pour parvenir ... -
Use of maps for planning research farms
(1996)Topographic maps is the main type of maps used by farm managers. In agriculture, surveying is required to prepare topographical maps that indicate variations in the level of the land's surface. Topographical maps are the basis for farm planning. They can be used for determining slopes and land form. In combination with information on soil types, they can be used for farm planning. -

Precautions demploi des insecticides dans lagriculture
(1996)Les insecticides peuvent servir a combattre les insectes nuisibles mais sont generalement toxiques pour taus les animaux. Les insecticides d'une valeur DL50 aigue orale inferieure a 200 mg/kg ne devraient pas litre utilises dans les petites exploitations. Par mesure de precaution, I'emploi d'insecticides est soumis II certaines regles. En outre, les insecticides constituent un danger pour I'environnement : sol, eau, air et systemes biotiques. La plupart des insecticides courants sont des poisons ... -
Virus diseases of cowpea in Africa: IITA Research Guide, No. 53
(1996)Eight viruses are reported from cowpeas in Africa. Cowpea viruses are described from lowland, humid and sub-humid West Africa, as well as from mid-altitude ecological zones mainly found in eastern and southern Africa. Wherever facilities are limited and detailed characterization is not possible, a simple procedure using a combination of serology (agar-gel diffusion test), inoculation to test plants, and vector transmission studies, is proposed for the identification of the cowpea viruses reported ... -
Conservation des ressources genetiques par le stockage des graines
(1996)Il existe pi usieurs facons de conserver les ressources genetiques des cultures. La methode la moins chere et la plus simple consiste a stocker les graines. Toutefois, ce n'est pas toutes les cultures qui peuvent etre conservees sous forme de graines, car certaines se propagent vegetativement et produisent ou ne pro• duisent pas de graines; quand elles en,produisent, la viabilite de celles-ci est courte. Pour prolonger au maxi-mum la duree de vie des graines, il faut un bon entrepot et la maitrise ... -

Viruses and virus diseases of maize in tropical Africa
(1995)Seven viruses are known on maize in tropical Africa, however, information is still scanty. MSV is widely distributed in sub-Saharan Africa; other viruses are less widely spread or only of local importance. Information on viruses and virus diseases is useful to plant breeders in setting priorities. Resistance breeding is the most practical solution for control. -

Effect of banana leaf pruning on legume yield in bananalegume intercropping systems in Eastern Democratic Republic of Congo
(2013)As a result of declining farm/plot size and increasing food security needs, intercropping is practised by the majority of small-scale farmers in eastern Democratic Republic of Congo. A banana-1egume intercropping experiment was conducted at the Mulungu Research Station in South Kivu Province to evaluate whether banana leaf pruning improves legume biomass and grain yield without reducing banana production. Treatments consisted of combinations of three different levels of banana leaf pruning (maintain ... -
