Abstract
In order to study the effect of sowing dates and cultivation methods on yield and other characteristics of two cultivars of common bean (Phaseolus vulgaris L.) an experiment based on split plot design was carried out with three replications in 2007 at Khorramdarreh region of Zanjan province. Treatments consisted of three sowing dates (May 21, June 4&19), two cultivation methods (furrow and basin) and two cultivars (spotted bean Talash and red skin bean Naz). Parameters such as seed yield, biological yield, protein percent, seeds per pod, pods per plant, days to maturity, 100 seed weight, plant height, emergence% and harvest index were evaluated. Results of variance analysis showed that all of treatments had significant effects on seed yield and other parameters. Sowing date and cultivars affected seed yield, significantly (p≤0.05). Also cultivation method had significant effect on seed yield (p≤0.01). Best results for seed yield, pods per plant and seeds per pod were obtained in second date of sowing, furrow system and Naz variety. Highest and lowest yield obtained from June 4 (3878 kg/ha) and June 19 (3246kg/ha) dates, respectively. Highest protein content (21.2 %) obtained in June 19 and spotted bean (Talash) cultivar. The highest number of pods per plant obtained in June 4, furrow method and Naz cultivar.

Key words: Common bean, Cultivation method, Sowing date, Protein content, Yield
