RESPONSE OF LEUCAENA-LEUCOCEPHALA TO INOCULATION WITH RHIZOBIA FROM
TROPICAL LEGUMES
IQBAL R; MAHMOOD A
Abstract: Rhizobia isolated from root nodules of Albizia lebbeck, Arachis
hypogaea, Clitoria ternatea, Leucaena leucocephala, Medicago sativa,
Pithecellobium dulce, Sesbania sesban and Vigna unguiculata were tested
for their ability to produce root nodules on Leucaena leucocephala.
Amount of fixed N2 was measured. Except Arachis hypogaea isolates from
all leguminous plants produced nodules on L. leucocephala. Isolates from
V. unguiculata, A. lebbeck and P. dulce were most effective in nitrogen
fixation and induced substantial increase in dry weight and nitrogen
contents of the host plant.
