Abstract: 

In order to determine the effects of narrow row spacing on vegetative and reproductive characteristics of bean (Phaseolus vulgaris), an experiment was conducted in Khomein National Bean Research Station for two years (1998-1999) as split block design in randomized complete block with three replications. Three bean genotypes (C.O.S-16, Akhtar, WA4502-1) in verticl plots and four row spacings (50, 37.5, 25,18.75 cm) in horizontal plots were studied. Combined analysis of variance of experiment revealed that genotypes had significant differences in plant height, days to flowering, days to maturity, pod filling period, 100-seed weight and grain yield. C.O.S-16 had the highest plant height. Furthermore, this genotype had greater growth period than the others. Mean grain yield of spotted bean (C.O.S-16), red bean (Akhtar), and white bean (WA 4502-1) were 2569, 3050, and 2230 kg/ha, respectively. Row spacing significantly influenced the traits of days to flowering, days to maturity, pod filling period, 100-seed weight and grain yield. The greatest grain yield, up to 2971 kg/ha, was obtained from 37.5 cm row space.
