A field experiment was conducted to investigate effects of inoculation of faba bean with rhizobium GS374 on total yield and nodulation of faba bean in a fababean/maize intercropping system receiving nil or 225 kg hm^-2 N. Results show that biomass or grain yield of fababean in Treatment N₀ where fababean was inoculated rhizobium GS374 was similar to those in Treatment N₂₂₅ where fababean was not inoculated with rhizobium regardless of whether planted sole or intercropped. However, in Treatment N₂₂₅, nodulation of faba bean was facilitated by rhizobium inoculation. Biomass of fababean was significantly enhanced by rhizobium inoculation, intercropping or N fertilization as compared with their respective check, while grain yield was increased only by intercropping. Both biomass and grain yield of maize were significantly improved by N fertilization. In Treatment N₂₂₅no significant effects of rhizobium inoculation and intercropping were observed on biomass of maize, while in Treatment N₀, the effect of inoculation on grain and biomass yield of maize in the intercropping system was significant, increasing by 343% and 256%, respectively. Inoculation also significantly improved grain-yield-based land equivalent ratio (LER) in treatments receiving N and biomass-based LER in Treatment N₀. In addition, rhizobium inoculation markedly increased nodule number and nodule dry weight per faba bean plant, but its effect on nodule number was less in the intercropping system than in the sole system. So it is held that inoculation of bean crops with appropriate rhizobium is an approach to further promoting the merits of the legumious/gramineous intercropping system.
