The aim of this study was to determine the most appropriate planting density for the highest yield of mung bean (Vigna radiata L.) cultivars in Lordegan region. The study was carried out as a factorial experiment in a randomized complete block design with three replications. Factors included four mung bean cultivars namely Parto, VC۶۱۷۳A, VC۶۳۷۱۹۴ and Lordegan Local mung bean plus three different planting densities of ۳۰, ۴۰ and ۵۰ plants per square meter. Flowering date, physiological maturity date, plant height, number of pods per plant, number of seeds per pod, ۱۰۰-seed weight and seed yield were measured. Results of combined analysis of variance over two years showed that genotypes were significantly different in studied traits (except for number of seeds per pod). The effect of planting density was significant on all traits (except for ۱۰۰-seed weight and the number of days to maturity). The interaction between genotype and density was not significant for any of the traits. The highest grain yield (۱۳۵۷.۸ kg/ha) was obtained from VC۶۱۷۳A line a density of ۴۰ plants per square meter.
