Weed emergence pattern in vegetable garden was recorded for one year from April, 1992 to April, 1993 to establish effective weed control programs. In April, 1992, the top 10cm of soil from vegetable garden was put into three 32×25×7cm3 plastic trays kept in a greenhouse. Watering was done as needed. Emerged seedlings were identified and counted on every Monday until April, 1993. A total of 1,396 seedlings of 28 (or 29) species was recorded. Two conspicuous emergence peaks were observed in spring and fall. Predominant species whose seedlings emerged in spring included Portulaca oleracea, Digitaria ciliaris, Galinsoga ciliata and Amaranthus lividus var. ascendens. In fall, on the other hand, Erigeron canadensis, E. philadelphicus and/or Stenactis annuus were the predominant ones.
