Abstract
Vigna unguiculata(L.) Walp (cowpea) is a tropical legume of very high nutritive and economic values. A laboratory experiment was conducted to evaluate the BNF (biological nitrogen fixation) efficiency of 4 strains of Bradyrhizobium sp. (VUXYI, VUIEI, VUMDSI and VUIDI). From the results obtained these strains were classified into efficiency groups, with VUIDI being the most efficient and VUXYI the least efficient.The effect of inoculation was tested on 2 cowpea varieties in a field experiment. Remarkable increases in nodulation biomass and crop yield were observed. An increase from 58% to 81% in dry seed was obtained for the two varieties. A significance test revealed a significantly positive correlation between nodulation and biomass.
