The Effect of Arbuscular Mycorrhiza Fungi on Cotton Growth and Yield under Salinated Soil Condition

The aim of this study was to investigate the response of two cotton AN-Bayaut-2 and S-6524 ( Gossipium hirsutum L.) varieties to Arbuscular Micorrhiza Fungi (AMF) inoculation under salinated soil condition. The inoculation significantly increased N, P uptake and plant growth of both cotton varieties but micorrhization rate were considerable higher in AN-Bayaut-2 compare to S-6524 variety, 36,7% and 19.1% respectively. Micorrhization rate of root had a significant impact on plant growth and development during vegetation period. AMF formed a symbiotic relationship with cotton root in salinated soil enhanced a nutrient and water uptake of plant and growth of the plant as well as cotton yield.
