To examine the effect of Arbuscular Mycorrhiza fungi (AMF) (Glomumosseae) on nitrogen and phosphorous metabolism in two wheat varieties at jointing and heading stage under water deficit stress conditions. NPK content was more in leaves and roots of AMF inoculated plants. Activities of Nitrate reductase (NR), Nitrite reductase (NiR) and Glutamine synthetase (GS) decreased in leaves and roots under stress conditions. The higher activities of NR, NiR and GS in mycorrhizal plants could also be attributed to the positive effect of inoculation on N acquisition and assimilation in plants. Higher phosphatase activity in WH 1025 than in WH 1105 might help the plants by maintaining higher P acquisition under stress conditions. Hence, overall results suggest that mycorrhizal symbiosis plays a vital role in enhancing the activities of nitrogen and phosphorous metabolizing enzymes and increased the nutrient content that enables the host plant to sustain the water stress conditions.
