In order to investigate the effect of planting arrangement on growth indices and grain yield of a red bean cultivar (Sayyad cultivar), The experiment was conducted in a split-plot randomized complete block design with 4 replications in Jihad Agricultural Services Center of Al-Mahdi town, Azna. The main factor consisted three row spacings including 20, 30 and 45 cm and the sub-factor consisted three densities including 40, 50, and 60 plants m-2. The results showed that by reducing the row spacing dry matter accumulation, CGR and LAI at different periods of growth and grain yield increased. However, changing the row spacing did not have a significant effect on RGR and NAR. With increasing plant density, the dry matter accumulation, CGR and LAI over the course of plant development, RGR and NAR in reproductive stage and thus grain yield increased. Plant density had no significant effect on RGR and NAR in vegetative growth stage and maximum NAR. Considering the increase in most traits in the row spacing of 20 cm and a density of 60 plants m-2, this type of planting arrangement might be suitable for cultivation of red been under similar environmental conditions in Azna, Lorestan, Iran.
