To investigate the effect of straw mulch on irrigation management and operation of common bean, split plot experiment in a randomized complete block design with three replications was conducted in the city of Astaneh Ashrafiyeh during the growing year 2012. These studies include no irrigation and irrigation management with three different Intervals (6, 12 and 18 days) and an amount of straw mulch (0, 1, 2 and 3 cm) in each plot was selected. The results showed that a different level of irrigation management and mulch on yield was found to be significant. But its effect on seed yield was was found non-significant. Mean data showed that the highest yield in irrigation management (2431.3 kg haG1) is obtained for 6 days interval of irrigation. A yielddifferent level of mulch with 1585.6 kg haG1 was higher than without mulch. At the end of the season the numbers of seeds podG1 and plant height and root traits were also measured.
