   Subscribe/Renew Journal


Nitrogen fixation studies were carried out in four tree species viz., Albizia lebbeck, Acacia nilotica, Dalbergia sisoo and Leucaena leucocephala under potculture conditions. Maximum plant height, nodule biomass, and nitrogenase (acetylene-ethylene reduction) activity was noticed in case of Leucaena followed by Albizia, Acacia and Dalbergia. The amount of n moles C2 H2, produced per plant h-1 and per nodule h-1 was 550.9 and 4.44 in Albizia, 488.88 and 4.40 in Acaica, 125 and 2.28 in Dalbergia and 1772.3 and 12.31 in Leucaena.

Abstract


Nitrogen fixation studies were carried out in four tree species viz., Albizia lebbeck, Acacia nilotica, Dalbergia sisoo and Leucaena leucocephala under potculture conditions. Maximum plant height, nodule biomass, and nitrogenase (acetylene-ethylene reduction) activity was noticed in case of Leucaena followed by Albizia, Acacia and Dalbergia. The amount of n moles C2 H2, produced per plant h-1 and per nodule h-1 was 550.9 and 4.44 in Albizia, 488.88 and 4.40 in Acaica, 125 and 2.28 in Dalbergia and 1772.3 and 12.31 in Leucaena.
