Yield and yield components of red bean cultivars in different planting pattern as a second cropping in Kermanshah climate, Iran

Article published on February 09, 2015 Abstract To evaluate the effect of planting pattern on yield and yield components of different bean cultivars as second cropping in Kermamanshah province, this experiment carried out based on split plot arrangment in randomized compplet block design with three replications. Planting Pattern as 15 × 12 cm, 30 × 6 cm, 45 × 4 cm, respectively, so that the density of 55.5 plants.m -2 were observed and considered as main plots. Main plots consisted of three planting patterns with 15, 30 and 45 cm as row spacing and 4, 6 and 12 cm as plant spacing. Six bean cultivars including Akhtar, Goli, Pak, Shokofeh, Dorsa and Daneshkadeh were assigned sub-plots. After harvesting canola as main crop in this field, bean cultivars were cultivated as second crop in summer of 2013. Analysis of variance showed that planting pattern on grain yield, biological yield and harvest index were significant at the 1% level. 100-grain weight and number of pods per plant were significant at the 5% level, but had no significant effect on number of grains per pod. Cultivar had a signifcent affect on the number of pods per plant, grain per pod, grain yield, biological yield and harvest index at the 1% level. Protein content was affected by cultivar at the 5% level. Interaction effect between planting pattern and cultivar were significant on grain yield, biological yield and harvest index at the 1% level, but pods per plant, grain per pod and 100-grain weight were no significant by plantig pattern and cultivar. The heghest grain yield with mean of 445 g.m-2 was observed in planting pattern of 45 cm and Dorsa cultivar and the lowest grain yield with mean of 10 g.m-2 was bserved in planting pattern of 15 cm and Akhtar cultivar, respectively.
