ABSTRACT
A pot experiment was conducted in the net house of the Department of Plant
Pathology, Sher-e-Bangla Agricultural University, Dhaka during the period
from May 2006 to December 2006 with a view to study the role of Arbuscular
Mycorrhizal (AM) fungi on growth and nutrient uptabe of some legumes. A
positive growth response to AM was observed in all the selected legumes. The
seedling emergence, plant height, shoot length and root length of inoculated
legumes were comparatively higher then that of uninoculated control. The
mycorrhizal inoculation suppressed root rot, damping off and leaf blight disease
of BARI Mungbean and suppressed root rot, damping off, leaf blight and leaf
spot disease of Lentil and Chickpea. The inoculated plants showed early
flowering and fruiting in comparison to uninoculated control. Mycorrhizal root
colonization differed among the crops ranging from 20.00 to 49.75% and
mycorrhizal dependency varied from 8.85 to 55.22%. Increased nutrient (N, P, K,
S, B and Zn) uptabe was recorded with the inoculated plants. Among the
inoculated legumes comparatively higher N, P and K nutrient uptabe was
observed in Pigeonpea, Cowpea and Chicbpea respectively; where as S in
Pigeonpea, B in Cowpea and Zn in Soybean.
