Abstract

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 (P<0.01) on all measured parameters except spikelet number and density. SMC application had a positive effect on all measured parameters whereas reduced wheat spikelet density. There was a significant interaction between SMC and water stress in terms of extrusion length, plant height and most of yield attributes. At each given water stress levels, application of SMC significantly improved the mentioned traits. According to the results, in all moisture levels, the maximum increase was observed in 50 Mg.ha-1 of SMC application for grain number per plant (4 to 5.7 fold) followed by grain yield (3.2 to 3.6 fold) and biological yield (2.9 to 3.3 fold). Therefore, it seems that in different water levels, SMC could be considered as a suitable candidate to apply for organic fertilizer.
