Abstract:
To study the effect of arbuscular mycorrhizal fungi on morphological and physiological characteristics of maize in different levels of phosphorus fertilizer, a greenhouse experiment as factorial arranged in completely randomized design with three replications was carried out at Islamic Azad University Miyaneh Branch, Iran. The experimental treatments consisted of mycorrhizal inoculation with Glomus mosseae (inoculation and non-inoculation) and four levels of phosphorus chemical fertilizer (control, 13, 26, and 39 kg P per ha). Results showed that the highest values of wet and dry biomass (224.08 and 172.47 g Plant-1, respectively) were belonged to mycorrhizal inoculation in 39 kg P per ha. Also, the lowest values of wet and dry biomass (120.74 and 95 g Plant-1, respectively) were belonged to mycorrhizal non-inoculation at control level of phosphorus fertilizer. The highest values length, weight and number of ears (23.22 cm, 116.32 g and 4.25, respectively) were related to mycorrhizal inoculation in 39 kg P per ha. Totally, the result indicated which 39 kg P per ha at mycorrhizal non-inoculation had not only higher wet and dry biomass than 26 kg P per ha at mycorrhizal inoculation but also it had lower wet and dry biomass than 26 kg P per ha at mycorrhizal inoculation. Generally, the results of this research shows the increasing amount of biomass, chlorophyll and leaf phosphor concentration with improving in morphological and physiological characteristics of maize due to use of arbuscular mycorrhizal fungi. Also, absorption of phosphor and plant yield were increased by applying a low amount of phosphor fertilizer.
