Abstract

A commercially available small garden seeder was modified to improve the precision planting of uncoated lettuce seed. The modified seeder is light weight, is adapted to planting small quantity seed lots, can be rapidly cleaned of remnant seed, and is designed for research and home garden use. Acceptable single seeding of uncoated lettuce seeds in the laboratory averaged 41.5%. Acceptable single seedling emergence in the field averaged 36.8%, a 13.6% improvement in the existing efficiency over the small plot seeder currently used. Minor modifications could make this planter design adaptable to most small-seeded crops.

Abstract

The design and operation are described for a mechanical aid for threshing individual seed heads of globe artichoke (Cynara scolymus L.). Seed extraction is accomplished by holding the seed head manually in the path of ribbed, rubber fingers mounted on a revolving drum. The use of the thresher reduces threshing time to less than 10% of that required to extract seeds by hand, and the percentage of recovery of seeds in the head is increased.
