Determination of the Effect of Different Sowing Dates on Growth and Yield Parameters of Some Dry Bean (Phaseolus vulgaris L.) Varieties

The experiment was carried out at Dicle University, Faculty of Agriculture Department of Field Crops in 2018 spring and summer season. The aim of this study was to evaluate the effect of different sowing dates (March 10, April 4 and May 4, 2018) on the phenological, morphological and yield performances of six dry bean varieties. The experiment was established randomized complete blocks design in split plots with three replications. The sowing dates significantly affected to the days to seed emergence, days to first flowering, days to 50% flowering, days to maturity, first pod height, number of branches per plant, pod width, plant weight, pod weight per plant, number of pods per plant, number of seeds per plant, seed yield per plant, biological yield and seed yield. As the sowing date was delayed, there was decreased in all traits. The early sowing date provided better growth in cold tolerance varieties. Among the sowing dates, in early to mid-March sowing date was the most favorable for all varieties and Diyarbakir ecological conditions.
