Planting data and soil moisture retention are the most important factors influencing the increase crop yield. In order to evaluate the effect of planting dates and rice residue application (mulch) on growth and yield of cranberry bean, a factorial experiment arranged in a complete blocks design with three replications was conducted in Koochesfehan (Rasht, Iran). The factors were planting dates 3 levels (23 April, 30 April and 7 May) and mulch application with 2 levels (with mulch, without mulch). Results indicated that planting dates had significant effect on parameters, exactly number of green pods had significant effect on parameters, exactly number of green seeds, number of flowers, biological and productivity score. Interaction between planting dates and mulch had significant effect on number of dry seeds, number of root nodules, dry seed yield, biological yield and productivity score. Comparison of means indicated that first planting date had the highest effect on parameters; number of green seeds (29.79), number of dry seeds (30.03) and number of flowers (16) per plant, dry pod yield (1139.58 Kg/ha) and harvest index (47.93%). Mulch application had the highest effect on parameters; number of green pod per plant (8.33), pod yield (1085.28 Kg/ha) and harvest index (42.68%). Overall the first planting date (23 April) and application of mulch had higher effect on dry seed yield and productivity score of cranberry bean.
