Influence of seeding density on agronomic parameters of cowpea (Vigna unguiculata L.) accession grown in Daloa, west center of Côte d’Ivoire

Cowpea (Vigna unguiculata L.) is most important food legume in tropical regions of Africa. In Côte d'Ivoire, its cultivation neglected and carried out on small surfaces with a strong concentration North the country. The objective this study was to determine, addition sowing density, ideal number plants per hole for better cowpea production. Experimental design used completely randomized Fisher block three replications six treatments block. tested spacings are : 20 cm x 01 plant hole, 02 hole; 30 40 hole. Observations were made nine agronomic parameters (plant height, leaves, branches, span, fresh biomass, pods, weight dry pods grain weight. Results show that seeding densities significantly influence parameters. Thus, lowest (62500 plants/ha) corresponding 40cm spacing one gave best yields while highest (250000 20cm two all
