Variability of Grain Yield and Yield Components of White Bean (Phaseolus vulgaris L.) Cultivars as Affected by Different Plant Density in Western Iran

In order to study the effect of plant density on yield and yield components of white bean cultivars an experiment was conducted as split plot in randomized complete block design with four replications in Agricultural and Natural Resources Research Center of Ilam, Iran during 2009-2010. The main and sub plots included cultivars (Shokofa and Danshekadeh) and plant density (13, 16 and 22 plant/m ), respectively. The 2 results of variance analysis showed that cultivar had significant effect on plant height, number of grains per plant, grain yield and harvest index. Shokofa cultivar had the highest plant height (188.5 cm), number of grains per plant (173.6 grains), grain yield (2591.8 kg ha ) and harvest index (45.5 %). Plant density had significant 1 effect on number of branches, number of pods per plant, grain yield, biological yield and harvest index. The plant density of 13 plants per m had the highest number of branches (28.5 branches), number of pods per plant 2
