The present experiment was conducted in the net house of the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh with a view to studying the role of Arbuscular Mycorrhizal (AM) fungi on growth and nutrient uptake of some vegetable crops. Root segment of Cassia tora along with rhizosphere soil was used as inocula. In inoculated pot, raw inocula were used and in control pot sterilized root and soil inocula were applied to ensure same nutritional condition. Different number of seeds was sown based on seed size of the selected vegetables. A positive growth response to AM was observed in all the selected vegetables such as spinach (Spinacia oleracea L.), Indian spinach (Basella alba L.) and water spinach (Ipomoea aquatica). The seedling emergence, plant height, root length and shoot length of mycorrhiza inoculated vegetables were comparatively higher than that of un-inoculated control. Mycorrhizal root colonization differed among the crops ranging from 18.65 to 44.26%. The mycorrhizal inoculation suppressed root rot, damping off and leaf spot disease of spinach, Indian spinach, and water spinach. Mycorrhizal dependency was ranged 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 and water spinach whereas Zn and Fe uptake was found higher in spinach, respectively. Arbuscular Mycorrhizal fungi showed positive response in case of plant growth parameters and it could be used as a bio-fertilizer.
