Effect of intercropping on nodulation and N2-fixation by groundnutP T CNambiarauthorM RRaoauthorM SReddyauthorC NFloydauthorP JDartauthorNodulation and N2-fixation of groundnuts were studied in pure stands and intercropping systems. Intercropping with maize, sorghum or Pennisetum americanum reduced nodulation and N2-fixation. This is ascribed to shading of groundnuts by cereals and the consequent decrease in photosynthesis of the legume canopy.Groundnut1983Cambridge University Press Article
