Abstract
本試驗利用臺農68號及67號（對照）二品種探討氮肥用量及有機肥料，影響稻米品質及產量變化情形。於民國74年第二期作及75年第一期作在嘉義分所溪口農場進行。米質理化學特性上，僅在第一期作臺農68號品種之直鏈性澱粉含量較高，而第二期作兩品種間差值不大，期作間差異以第二期作含量較高。施用有機肥料造成第一期作粗蛋白質含量在各處理間差異顯著，第二期作則無此現象，並且施用後可提高白米率，變化直鏈性澱扮含量不而以施用穀殼之處理區所提高產量之表現較爲突出。Rice varieties, Tainung 68 and 67 (C K) were used to study the effects of different N levels and organic matter (rice husk and duck disposal) on yield and rice quality, such as grain appearance, chemical properties and eating quality. Tainung 68 had a higher amylose content than Tainung 67 in the first crop, but not in the second crop. In general, amylose contents were higher in the second crop than in the first crop. Application of organic fertilizers caused the significant difference in crude protein content among treatments in the first but not in the second crops. It seems that organic matter tended to increase rice yield, promote ,head rice rate and change amlyose contents. In the panel test for eating quality; the rice in the plot received organic fertilizers had few incidence to be scored as ”bad”. The eating quality of Tainung 67 did not get worse due to increased N-levels, while Tainung 68 did, indicating that this variety is more sensitive to cultural management.
