In order to determine the appropriate plant density of spotted bean in Yasouj, a field experiment
was conducted in 2008 as a factorial in a randomized complete block design with three replications.
Three spotted bean cultivars (Keshavarzi, Talash and Oshtori) were sown at five plant densities (10,
20, 30, 40 and 50 plant.m-2). Results showed that effect of plant density, cultivar and interaction
between them on grain yield were significant. The maximum and minimum grain yield was obtained
at 50 plant.m-2 (539.10 g.m-2) and 10 plant.m-2 (203.43 g.m-2), respectively. Number of pods per square
meter and grain per pod at plant density of 50 plant.m-2 were higher than the other plant densities.
Talash grain yield was higher than the other cultivars. Number of pods per square meter of Talash
cultivar was higher than the other cultivars. Oshtori cultivar at plant density of 10 plant.m-2 with 161.7
g.m-2 and Talash cultivar at 50 plant.m-2 with 606.6 g.m-2 had maximum and minimum grain yield,
respectively.
