The effect of spent mushroom compost (SMC) on yield and yield components of wheat (cv. Azar2) under different moisture conditions was evaluated in pot experiment at Dry-land Agricultural Research Institute in 2010. Experiment arrangement was factorial based on complete randomized design with four replications. Treatments were SMC at three levels (0, 25 and 50 Mg.ha-1) and water deficit stress at three levels (-0.3 or field capacity, -5 and -10 bar). Some morphological, yield and yield components of wheat were determined. Results indicated that water stress had a negative and significant (
