Abstract
Taro, cv. Betelnut, were planted in paddy fields in 1979 and 1980 showed that the higher the plant density, the higher the plant and yield. However, size, weight and number of main corm or cormels produced on each plant were negatively correlated to the plant density. The highest main corm yield was recorded in the plot with a spacing of 60 x 20 cm (83,300 plants/ha) of 36 tons/ha and 55 tons/ha and the lowest in the spacing of 60 x 60 cm (26,600 plants/ha) of 17 tons/ha and 21 tons/ha respectively in 1979 and 1980. Total yield (main corm + cormels) also showed the highest in the spacing of 60 x 20 cm of 43 tons/ha and 63 tons/ha and the lowest in the spacing of 60 x 60 cm of 22 tons/ha and 26 tons/ha respectively in 1979 and 1980. This information is valuable for the farmers to cultivate taro in the paddy fields.
檳榔心芋於 1979 及 1980 年分別種植於行距 60 公分，株距 20，30，40，50 及 60 公分即每公頃種植 83,300 株； 53,300 株； 40,000 株； 33,300 株及 26,600 株等五種不同種植密度之水田，試驗採用逢機完全區集設計四重複，每小區種植 6 行，行長 5 公尺，小區面積為 18 平方公尺。兩年之試驗結果顯示植株之高度與產量均隨種植密度之增加而顯著增加，然而單株母芋或子芋之大小、鮮重或數目均與種植密度呈負相關之趨勢，母芋之產量或母芋加子芋之總產量均以 60 公分 × 20 公分即每公頃種植 83,300 株者為最高，而以 60 公分 × 60 公分即每公頃種植 26,600 株者為最低，此資料顯示在臺灣南部地區檳榔心芋水田栽培之最適種植距離應為 60 公分 × 20 公分即每公頃種植 83,300 株，此可提供農民種植水田芋頭之依據及學術研究之參考。
