Cowpea is one of the most important grain legumes of Niger, which is the second largest producer of the crop in Africa. About 764,000 MT of cowpea are produced annually on about 4,132,000 ha (Figure 1). Local consumption has grown significantly in recent years. This is bound to have a positive impact on people’s nutrition and health. Cowpea haulms are used as animal feed, helping to increase livestock productivity. Farmers often grow long-duration spreading varieties for fodder (Singh et al., 2003).
Groundnut is a major source of income and protein for rural households in West and Central Africa (WCA). It is a women’s crop and as such, women farmers play a major role in groundnut value chains. They are the major producers, processors and marketers. However, they have been constrained by inadequate institutional, policy and market support to improve seed and groundnut oil and paste value chain efficiencies.
L'identification des variétés d'arachide et niébé tolérantes à la sécheresse et bonne fixatrices d'azote augmenterait leurs productions et celles des céréales associées ou en rotation. Des variétés d'arachide et de niébé ont été évaluées, au champ et en pots, en condition de sècheresse ont réduit la plupart des paramètres étudiés , dont notamment le nombre nodules (40%) et le poids des gousses (30%).
