Abstract

Seed physiological maturity was studied to determine the optimum harvest time for dill seed production at the Faculty of Agriculture, Ubon Ratchathani University during October 2005 to March 2006. Seed reached physiological maturity at 35 days after anthesis with germination of 37.5%. At this stage seed moisture content was too high to harvest and germination percentage was low. The optimum time to commence harvesting should be after seed physiological maturity (45-70 days after anthesis) but before seed shedding. At these stages, seed color was dark brown with 9-12% seed moisture content. The highest seed germination (68.5%) was at 70 days after anthesis while seed started to shed.
