McKnight Foundation Collaborative Crops Research Project No: 06-741 Development and promotion of Alectra resistant cowpea cultivars for smallholder farmers in Malawi and Tanzania Conclusion Cowpea grain and leaves are widely consumed in the two surveyed areas. The contribution of micro and macro nutrients is significant for both developed lines and local varieties but with leaves having greater mineral content than grain. Therefore awarenessraising within communities to consume more cowpea leaves is required. However the amount produced per household is low compared to requirements. Consequently cowpea intake per capita is low, and does not meet the RDA. However, since households in both areas still have ample land they should be encouraged to increase the area planted as well as planting higher yielding varieties in conjunction with preferred local varieties. This does however require further market investigation. Other important nutrients such as vitamins, amino acid profile and levels of antinutritional factors (tannins and phytates) should also be further investigated. The vitamins and amino acids influence in nutrition while the antinutritional factors influence on the bioavailability of the nutrients in the body. Acknowlegement The authors would like to acknowledge the financial assistance from the McKnight Foundation, who facilitated successful survey and laboratory analysis of macro and micronutrients.
