The Impact of Arbuscular Mycorrhizal (AM) fungi and water stress on development and yield of onion (Allium cepa L.)

Abstract

A field study was conducted to determine the effect of arbuscular mycorrhizal (AM) fungi inoculation on growth of onion grown under well watered and water stressed pot culture conditions. The data was collected at an interval of 15 days i.e. after 45, 60, 75 and 90 days. Root colonization with AM fungi occurred in under water-stressed and well-watered conditions, but the extent of AM fungi root colonization was higher under well-watered than under water-stressed conditions. Data was collected regarding length of leaves, root, diameter and weight of onion after 45, 60, 75 and 90 days. However, inoculation with AM fungi has improved onion bulb yield. The result indicates from AM fungi inoculation benefited more than that of especially under water-stressed conditions.
