Effect of Agro-ecological Zones on the Agronomic Performance of Cowpea in the Central African Republic

Cowpea (Vigna unguiculata (L.) Walp.) is a legume cultivated and consumed in the Central African Republic. Few studies have been carried out on cowpea For this reason, four local accessions (Kahkir, Gbarah, Aie-toung Bambalassa) collected different localities were evaluated at three sites. Yield squares laid according to randomized block design with replications. These selected basis of quantitative parameters such as height, growth, number pods, weight pods (g), pod yield, haulm yield seed yield. The data was subjected analysis variance (ANOVA). results show that are statistically among studied. emergence rate all over 75%. showed height plants significantly compared study areas (p < 0.05). susceptible viral diseases prevalence more than 50 98%. Kahkir Gbarah best pod, biomass production most productive sites M'Baïki.
