Abstract
在霧峰（本所）一處探討第一期作水稻後之田菁中間作及其處理方式（整地掩埋及不整地敷蓋）對秋作玉米生育，收量及氮需要量之效果。
一期稻作收穫數天前撒播之田菁生育迅速，到秋作玉米播種時乾物生產每公頃可達5公噸左右，含氮、磷酐、氧化鉀各約120、25、及90公斤。n the cropping system converting the second crop rice for corn, the paddy fields after the harvest of the 1st crop rice are either fallowed or planted with interseason crop during the summer season. (Corn is not suitable for cultivation during summer due to the rainy weather and typhoon harzards.) Sesbania roxburghii is a suitable green manure to be grown as an interseason crop. The Sesbania plants grow profusely and the dry matter yield of the shoot during the period from early July to early September amounts to 5.1 t/ha, which contain 107, 23 and 80 kg/ha of N, P2O5 and K2O respectively.
