Effects of Sowing Amounts and Treatments on Agronomic Characteristics and Yield in Schizonepeta tenuifolia Briquet in Southern Part of Korea

Performance of direct seeded upland field Schizonepeta tenuifolia Briquet in Southern areas of Korea was evaluated at different seeding methods(drilling and broadcasting) and seeding rates(1.5, 2.0, 3.0 and 3.5 l/10a). There were no differences in the yield components such as length of stem and ear diameter of stem number of branch, internode and ear, and yield of fresh and dry stem between the seeding methods with drilling and broadcasting, but yield components such as length of stem and ear, diameter of stem, number of branch , internode and ear, and yield of fresh and dry stem increased with seeding rates of from 2.5 l/10a to 3.5 l /10a. Therefore potimum rates and methods of sowing were from 2.5 l/10a to 3.5 l /10a with seeding at the drilling and broadcasting
