Abstract
The effect of Rhizobium sp. and Meloidogyne incognita on nodulation, nitrogen fixation and translocation of Fe and Zn in the shoot of mungbean (Vigna radiata) cv. SML-32 was investigated in plants grown in the presence of different concentration of Fe. Application of Fe at 20 ppm produced the maximum number of nodules per plant, nitrogenase activity of nodules, dry weight of shoots per plant and N content of shoot. However, 30 ppm Fe had an adverse effect on all these characters and reduced the translocation of Fe and Zn in the shoot.
