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 uptake of vegetable
crops(Brinjal,Tomato,ChiJIi,Okra and Data). Significant positive growth
response to AM was observed in all the selected vegetables. The seedling
emergence, plant height, shoot length and root length of inoculated vegetables
were comparatively higher than that of uninoculated control. Mycorrhizal fungi
inoculation significantly enhanced disease reduction in all the treatment
compared to control plant. In case of Okra the incidence of damping off and
foot rot were )0.78% and 6.48% in noninoculated plant whereas 4.52% and
3.24% in inoculated mycorrhizal plant respectively. No leaf spot disease in
inoculated plant was found. Mycorrhizal dependency (MD) of the vegetables
ranged from 15.58% to 31.38%.Among the vegetable studied the "highest
mycorrhizal dependency (31.38%) was observed in Brinjal and the lowest MD
(15.58%) was observed in Chilli. Okra recorded the second highest MD
(26.82%) which was followed by Data (24.79%) and Tomato (18.56 %). N, P,
K, Zn and Fe uptake were. influenced significantly by the inoculation of AM
fungi over control in all the tested vegetables.
