Analyse sexospecifique dans la production agricole: Guide de recherche de lIita, No. 58
(1998)La ‘sexospecificite' est un concept utilize en sciences socials pour etudier les roles et les activites des homes et des femmes. Ces roles sont souvent socialement defines, et faconnes par les traditions et les croyances d'une culture donnee. Bien que les femmes contribuent entre 60 et 80% de la productionagricole dans les pays en developpement, les agricultrices ont moins de chance de beneficier des services d'encadrement et des technologies qui pourraient ameliorer leur production. Par consequent, ... -
Amelioration de la duree de conservation du plantain et de la banane: Guide de recherche de lIita, No. 62
(1998)Le plantain et la banana sont des cultures vivrieres importantes dans la zone humide d' Afrique sub-saharienne. Le plantain et la banana ont le granddesavantage d'avoir des fruits tres perissables. Par consequent, les cherchurs tentent de trouver les voies et moyens d'en prolonger la duree de conservation. On peur utiliser plusieurs methods pour prolonger la duree de conservation. Les fonctionsphysiologiques les plus importantes affectant la qualite du produit pendant la conservation sont la ... -
Agronomy of cassava: IITA research guide, No. 60
(1997)Even though cassava is a durable crop, it has certain husbandry requirements and is responsive to favorable crop management practices. Healthy, fresh stem cuttings from mature cassava plants are the best planting materials. Depending on moisture conditions of the soil, farmers plant cassava cuttings vertically, at an angle, or horizontally. Slow initial development of sprouts makes cassava susceptible to weed competition in the first 3-4 months. Therefore, weed control involves cultural, biological, ... -

Insect pests of maize in storage: biology and control
(1998)Damage and losses to stored maize in Africa are often severe. Storage pests of an area have to be identified to determine whether they merit control and to choose appropriate control methods. Know ledge of the biology of pests and of factors influencing preharvest and postharvest infeststion is important to control insect pests in maize storage. -
Integrated assessment of crop–livestock production systems beyond biophysical methods: role of systems simulation models
(Elsevier, 2018)Crop–livestock farming systems that are predominant in Africa, are complex with various interrelated ecological and economic factors. They involve multiple products or benefits (intended and nonintended), with trade-offs and synergies occurring both on- and off-site and varying over time. Understanding both simplistic relationships and complex interactions between climate and agricultural production systems to determine overall system efficiency and impacts on human well-being is a major challenge. ... -
Ex post impact assessment of agricultural research in subSaharan Africa: the IITA experience
(2007)The International Institute of Tropical Agriculture (IITA) and its research-for-development partners have made substantial contributions to food security, poverty reduction and environmental protection in sub-Saharan Africa. Technologies developed and largely diffused include high yielding varieties (cassava, cowpea, yam, maize, soybean, plantainbanana), Integrated Pest Management of varieties resistant and tolerant to pests and diseases, biological control of pests and alien invasive species, ... -

Effectiveness of breeding and disseminating CMDresistant cassava varieties in western Kenya
(2005)In 1996, Cassava Mosaic Disease in Western Kenya depressed productivity and de-stabilized markets. The study assesses the effectiveness of breeding and disseminating CMD-resistant varieties in westernKenya by determining the extent of adoption and impact on farmers' income of the new varieties vis-àvis the level of investment in the program as well as the factors that influenced their adoption. Results show that the new varieties significantly increased production and marketing potential of cassava ...
