Abstract :

To evaluate the effect of chickpea cultivars ( Azad, Arman, Hashem and Adel ), three plant density ( 31.3, 38.5 and 50 m ) and weed control on yield and yield components of pea, an experiment was carried out on the farm of Agricultural Research Station, Razi University of Kermanshah in 2015. Design was conducted in factorial arrangement using randomized complete block design with three replications. The measured traits included the number of pods, main branch, seeds per pod, grains per plant, grain weight per plant, 100 grain weight, grain yield and biological yield. Analysis of variance showed that the effects of cultivars and weeding were significant for the traits at one percent. Effect of plant density and interactive cultivars × density were noticeable at the level of one percent for more characters except the number of seeds per pod and number of main branches per plant. Azad was the best cultivar with the greatest amount of seeds per plant, number of pods, number of main branches, weight of grains per plant, grain yield and biomass, 9.47, 8.89, 2.74, 2.59 gr and 1103 and 2953.8 kg. ha, respectively. Density of 31.3 perm2 was the most appropriate density for the number seed per plant, number of pods, seed weight per plant, biomass and grain yield per unit area, with 10.3, 9.44, 9.75, 3158 and 1114.7 kg ha respectively. According to our survey Hashem and Azad cultivars with the density of 31.3 plant per square meter together with weed control were the most suitable for the temperate region of Kermanshah.
