In order to evaluate yield and seed protein of some determinate and indeterminate bean (Phaseolus vulgaris L.) cultivars response to different sowing dates, a field experiment was performed in 2014 cropping season as split plot arrangement based on complete block design with three replications in Talesh, Iran. Five sowing dates including of 5 May, 15 May, 25 May, 4 June,14 June and five bean varieties including of Sadri (indeterminate), Goli (indeterminate), Akhtar (determinate), Pak (semideterminate), Dorsa (indeterminate) and along with local Pach bean colony (determinate) as check were randomized in main plots and sub plots, respectively. In this experiment, semideterminate Pak variety had the highest seed yield at the first sowing date (5 May). But, there was not significant difference between seed yield of semideterminate Pak variety and determinate local Pach bean colony. The highest pod number per plant obtained in semideterminate Pak variety under the first sowing date (5 May). The highest biological yield belonged to semideterminate Pak variety at the fifth sowing date (14 June). In addition, seed protein content increased in delayed sowing date. So that, there was inverse relationship between seed yied and seed protein content. Under Talesh climatic condition, important indices for seed yield enhancing in studied local bean colony and varieties were comprised pod number per plant, seed number per pod, 100 seed weight and harvest index. In general, the first sowing date (5 May) caused to enhance seed yield in semideterminate Pak variety and determinate local Pach bean colony under region climatic condition, respectively.
