Abstract
爲探求本省各地優良水稻品種，臺南5號、臺北309號、新竹56號、臺中184號、高雄137號之最適密植度及氮肥量，於民國59年第一期作及第二期作在、樹林、中壢、員林、高雄四處辦理本試驗。各試驗地使用兩品種，三平準氮肥量，第一期作100，130，160Nkg/ha，第二期作80，110，130N kg/ha，三種密植度25×20cm，30×12cm，25×12cm，以裂區設計進行田間試驗。
In order to determine the optimum plant spacing and nitrogen level for some popular rice varieties of Taiwan, namely, Tainan 5, Taipei 309, Hsinchu 56, Taichung 184 and Kaohsiung 137, field experiments were carried out at four localities, i.e. Sulin, Chungli, Yuanlin,, and Kaohsiung. A split plot design was laid out at each locality using two varieties, three levels of nitrogen (100130, 160 N kg/ ha in the first crop and 80, 110, 140 Nkg/ha in the second crop) and three plant spacings (25×20crn, 30×l3cm, 25×12cm).
