Abstract
This study was conducted to select a desiccant improving the harvesting efficiency of sesame seeds and establishing a safe use method. Non-selective herbicides such as glufosinate ammonium SL, glufosinate-P SL, fluthiacetmethyl+glufosinate ammonium SL, and thiafenacyl ME were used as a desiccant 20, 15, 10, and 5 days before sesame harvesting. The drying effect of the above-ground part of sesame was fastest in Tiafenacil treatment. The opening of the pods was around 50% and 90% in the desiccant treatment 15 and 20 days before harvesting, respectively. The yield of sesame seeds was highest 10 days before harvesting, followed by 15, 5 and 20 days before harvesting. Thousand-grain weight in the treatment 5 days before harvesting was similar to the treatment 15 days before harvesting. The germination rate of seeds was more than 90% in the treatment 5 and 10 days before harvesting. As a result of residual analysis of sesame seeds, it was predicted that Tiafenacil would be the most suitable desiccant in sesame because the corresponding component was detected below the standard amount only in the treatment of Tiafenacil among several tested desiccants.
