ABSTRACT

The present 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 some vegetable crops. A positive
growth response to AM was observed in all the selected vegetables The seedling
emergence, plant height, shoot length and root length of mycorrhiza inoculated
vegetables were comparatively higher than that of uninoculated control. The
mycorrhizal inoculation suppressed root rot, damping off and leaf spot disease of
Spinach (Spinacia oleracea L) and White gourd (Cucurbita vulgaris). The
mycorrhiza inoculated plants showed more leaves, branches, early flowering and
fruiting in comparison to uninoculated control Mycorrhizal root colonization differed
among the crops ranging from 18.65 to 53.48% and mycorrhizal dependency varied
from 18.57 to 36.36%. Increased nutrient (N, P, K, Fe and Zn) uptake was recorded
with the inoculated plants. Among the inoculated vegetables, comparatively higher N,
P and K uptake was observed in Spinach, Water spinach (Kalmishak) and Cucumber
where as Zn and Fe uptake was found higher in Spinach and in Cucumber,
respectively.
