The effect of row spacing and seed rate on grain yield, protein and agronomical traits of common bean (Phaseolus vulgaris L.) cultivars in Rasht
Abstract:
In order to evaluate the effect of row spacing and seed rate on grain yield and agronomical traits of Common Bean cultivars, a split factorial experiment based on the complete randomized block design with three replications was conducted at Rice Research Institute of Iran (Rasht) in 2008 and 2009 cropping years. Experimental treatments were row spacing in three levels of 20, 30 and 40 cm as main plot and seed rate in three levels of 70, 90 and 110 kg/ha and Common Bean cultivars including ‘Kkhaldar ghermez’ and ‘Kiashahri ghermez’ cultivars as sub plots. Mean comparison results showed that maximum grain yield was obtained from the second year, row spacing of 20 cm, ‘Kkhaldar ghermez’ cultivar and seed rate of 110 kg.ha-1 with averages of 1478.8 kg/ha, 1396.3 kg/ha, 1398.8 kg.ha-1 and 1414.1 kg/ha, respectively. Seed rate of 110 kg/ha also had maximum protein yield (334.0 kg/ha). Based on the results, the use of narrow row spacing, more seed rate and ‘Kkhaldar ghermez’ cultivar is better for planting Common Bean in the experienced region due to high grain yield and early maturity.
