Abstract Over two successive seasons (2011 and 2012), some morphological and yield parameters as well as some biochemical status of faba bean plants were studied in a field experiment under the influence of Rhizobium bacteria (R) and arbuscular mycorrhizal fungi (AMF) inoculation. The experimental studies were proceeded under the influence of the irrigation with either Nile water or wastewater. Throughout the plant growth, inoculation with R and AMF either singly or in combination, led to increases in the shoot length, number of leaves, flowers and pods and their dry weights, root nodules and AMF root colonization. At the harvest stage, the pods lengths, number of seeds per pod and the yield components of faba bean plants showed increases due to the inoculation with R and/or AMF. Regarding the biochemical status of the plant, the dual inoculation with R+AMF stimulated chlorophyll, protein and carbohydrates. The AMF inoculation (either alone or in combination with R) was generally more efficient in IAA induction than the R inoculation. Findings further demonstrated that reduced levels of chlorophyll, soluble protein and sugars were recorded in plants irrigated with wastewater. However, the activity of PPO was found to be greater in the plants irrigated with wastewater. Dual inoculation with R+AMF enhanced the nutrients absorption and translocation while led to a decrease in the heavy metals; Cr and Mn concentrations. |
