Studies on tree legumes
Twenty five species of tree legumes, belonging to genera Acacia, Albizzia, Bauhinia, Colophospermum, Dichrostachys, Leucaena, Peltophorum, Pithecolobium and Prosopis were examined for nodulation under pot culture conditions using unsterilized soil. Out of these, only nineteen tree-legumes nodulated. It was interesting to note that all the three species of Bauhinia and one each of Acacia, Colophospermum and Peltophorum did not nodulate both at Jodhpur and Delhi. Inoculation of tree legumes with their own rhizobial isolates, improved nodulation under sterilized conditions.
