摘要

本試驗主要探究插秧、條播及撒播三種栽植方式對新竹64號、臺農67號、臺稉4號、臺中189號及高雄142號五水稻品種之產量與米質之影響。結果顯示，三種栽培方式對產量均無顯著影響，僅品種間產量差異顯著，以新竹64號最高，早熟之高雄142號最低。第一期作平均產量，插秧與條播二種栽植方式差異不顯著，撒播顯著減收5.7%。五品種間之產量雖有顯著差異，僅高雄142號與其他四品種產量差異顯著。第二期作平均產量，以撒播栽植方式最高，條播及插秧次之，恰與第一期作相反。品種間差異顯著，以新竹64號產量與臺農67號顯著較其他品種為高。栽植方式之米質，如穀容重、糙米率、白米外觀品質等級，均未達差異顯著水準。兩期作之間無顯著差異。

Field studies were conducted in 1992 and 1993 to determine the effects of cultural methods and cultivars on grain yield and quality of rice.Rice cultivars HC 64, TNG 67, TK 4, TC 189 and KH 142 were planted by drilling, broadcasting and transplanting. There were no difference in grain yield among cultural methods. However, significant different in varietial performance for grain yield were observed; Highest yielding cultivar was HC 64 and KH 142 had the lowest yield.There was no significant difference in grain yield harvested in the first crop season between transplanting and drill seeding. However, grain yield reduced 5.7% by broadcast seeding.In second crop season, the highest yield was noted in broadcast seeding, significant difference in grain yield among the cultural methods was observed. Differences in grain yield among cultivars were significant; yields of HC 64 and TNG 67 were significantly higher than the average yields of other three cultivars.Results of quality analyses of the grain revealed that no difference in volumetric weight, milling percentage and appearance of grain were observed for all cultural methods and between two crop seasons.
