In order to study effects of different planting pattern on yield and yield components of mung bean cv. Gohar , a field experiment was conducted in summer season of 2003. The experiment was designed as a randomized complete block with a split-plot arrangement and four replications. Main plots were row spacing (50, 65 and 80 cm ) and subplots were within row distance (5, 7.5 and 10 cm). Results indicated that the highest and the lowest grain yield was produced at 50 and 80 cm ( 120 and 95.6 g.m-2) row spacing treatments, respectively. with a reduce in row spacing, the grain yield increased that might be attributed to higher grain per pod (8.7), pods dry weight (73.2 g.m-2) and biological yield (315.4 g.m-2). Within row distance did not have any significant effect on yield and yield components with the exception of 1000 grain weight and HI. The highest yield was produced by 50*5 cm planting pattern.
