Response of Wheat (Triticum aestivum L.) to Spent Mushroom Compost under Different Moisture Conditions

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 (
