| 摘 要： | Vigna unguiculata(L.)Walp (cowpea)is a tropical legume of very high nutrive and economic values.A laboratory experiment.was conducted to evaluate the BNF (biological nitrogen fixation) effciency of 4 strains of Bradyrhizobium sp.(VUXYI,VUIE1,VUMDS1 and VUID1).From the results obtained these strains were classified into efficiency groups,with VUID1 being the most efficient and VUXY1 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% ti 81% in dry seed was obtained for the two varieties.A significance test revealed a signifecantly positive correlation between nodulation and biomass.
