        Optimal usage of tea gardens during surface cutting period is one of the basic needs of gardeners in Guilan province.One of the solutions is the cultivation of legumes among rows of surface cutting tea bushes. In order to investigate the effect of application of different potassium sulfate levels and row Spacing on yield and yield components of bean in tea garden, a field study was conducted at Amlash in 2016 growing season. The experimental design was randomized complete blocks with split plot arrangement with three replications. The main plots included 4 levels row spacing (20 × 20 , 20 × 30, 20×40 and 20×50 cm) and subplots included 3 levels of potassium sulfate [ 0 (control), 75 and 150 kg/ha]. The highest pods per plant, seeds per pod, 100- seed weight, seeds per plant, grains yield, biological yield, harvest index, straw yield, pod yield, plant height and number branch per plant were obtained with 75 kg potassium sulfate. Plant spaces had significant effects on pods per plant, 100 seed weight, seed per plant, grain yield, biological yield, straw yield, pod yield and number of branch per plan and 20 × 30 cm plant spacing had the highest pods per plant, 100- seed weight, seeds per plant and number of branch per plant. The highest grain, biological, straw and pod yield was achieved at 20 × 20 and 20 × 30 spaces cm. Manuscript profile
