摘要

一、爲探討臺灣二期作稻增產問題乃舉行不同品種及插值期，田間試驗，木試驗採用裂區設計以肥料爲主試因品種與插植期爲副試因，在一期作用早，中、晚、熟三品種同時播種插秧無插植期之不同。二期作中生種臺中65號一品種分三個插植期，重複四次。
二、一期作不同成熟期品種間之產量差異極爲顯著概有依生育期間延長而增加之傾向。
三、二期作以不同插植時期對產量之影響最爲顯著，中植即立秋前之插植產量最高，晚植者產量最低。
四、一年二期作合併品種間產量比較之，在一期作種植晚熟種在二期作種植中熟種產量最高，一期作種植早熟種次之。
五、因子之交感效應則品種與肥料，肥料與插植期，品種與插植期，期作與品種，期作與插植期，均達顯著水準。

1. The present experiment is aimed to find proper transplanting time in both first second and crops in combination with different varieties, so that to increase the yield in second crop season.
2. Field experiment with spilt plot design were employed. It was found that difference in yield among three varieties tested was significant at 1% level. They were in the order of Chianan 2 (late maturity)＞Taichung 65 (medium maturity)＞ Norm 73 (early maturity).
3. In the second crop, significant difference at 1% level among transplanting times were found. The yield of Mid-transplanting time gave the highest yield (4, 688 kg/ha); yield of early transplanting was higher than that of late-transplanting.
4. The results of combined analysis with data of first and second crops after the homogeneity test showed that Mid-transplanting time with late maturity variety and fertilizer treatment B were the best of all.
