Abstract
Chinese chive (Allium tuberosum Rottler ex. Sprengel) has long been cultivated for culinary and medicinal use in East and Southeast Asia. The plant is a rhizomatous perennial and attains 30-40 cm in height. A. tuberosum grows in a clump of 5-10 bulbs, each producing 8-10 thin, flat leaves which can be cut several times during the growing season. Chinese chive is produced year-round in Thailand. Commercial crops can be established by dividing bulb clumps or via seed propagation. An experiment was conducted from June 2008 to October 2011 to compare the two propagation techniques for the production of green Chinese chive in the central region of Thailand. Plants established by seed propagation were ready for first harvest within 8 months, while plants established by clump division were harvested within 4 months. Seven harvests were obtained annually from each propagation treatment, yielding 58.29 and 57.45 t ha-1 y-1 for the seed propagation treatment and 56.34 and 55.96 t ha-1 y-1 for the clump division treatment during 2009 and 2010, respectively.
