Abstract

In order to investigate the effects of planting date and seed size on phenology, yield and yield components of Barakat cultivar of broad bean, an experiment was carried out on farm research of Gonbad Kavous University during 2011-2012. Two factors was planting dates in four levels of 5 and 19 November and 6 and 19 December and seed size (one seed weight) in four levels of 1-1.25, 1.25-1.5, 1.5-1.75 and 1.75-2 gr. The results showed that seed size affected only days from planting to 50% emergence whereas all traits were affected by planting date. In first planting date (6th Nov.) number of days from planting to 50% flowering and pod setting, plant height in 50% flowering and green pod harvesting time, fresh weight of plant, number of pods/plant, number of seeds/pod and plant, fresh seed weight in plant, pod length, fresh weight of one seed, and pod fresh yield was higher than other planting dates. The maximum days from planting to 50% emergence and harvest index was belonged to last planting date (20th Dec). In first planting date (6th Nov.) pod green yield was 22.85 ton/ha. The minimum green pod yield belonged to fourth planting date (20th Dec.) with 14.57 ton/ha. Harvest index in planting date of 6th November was 42.97% and in 20th December was 55.7%.
