Cabbage seed (Brassica oleracea L. Capitata group cv. Golden Acre) germinated in aerated water went through a pre- and post-radicle emergence separation by specific gravity to separate germinated from nongerminated seed. The desired specific gravity solutions were made with maltrin 250 and water. The percent germinated seed after separation was 99.3; recovery of germinated seed was 95.1%. A metering system was developed to precision plant the germinated seed. Metering rates of 0.5 and 2.0 seed/second were tested in the laboratory and greenhouse. Laboratory tests resulted in 5.7% doubles and 4.9% skips at 2.0 seed/second. Greenhouse test seedling emergence test resulted in 8% doubles and 15.6% skips at the fast rate. Spacing uniformity was acceptable for all tests.
