Abstract
本試驗係於民國四十七年起至四十八年止，分別在臺北、新竹、草屯三個地方舉行，二年間之試驗成績結果如下：
1. 氮之施用對大豆莖葉收量之效果甚微，對莢果產量而言，僅草屯乙地有7~18%之增產外，其餘各地即效應不顯著。就子實產量而言，臺北、草屯兩地雖依施氮量而增收，但未達顯著平準。可謂氮素對大豆收量之效應不甚明顯。
2. 磷之施用對大豆莢果收量之影響，僅草屯乙地顯著增收12~30%左右其餘各地肥效不顯著。
3. 鉀的施用對大豆莢果收量之影響，雖新竹及草屯兩地增收3~ 33%，但未達顯著平準。而臺北即呈負之效應，子實收量亦與莢果產量略有同樣之傾向。
The experiment was conducted in 1958~1959 in Taipei, Shintsu .and Chou-tun. According to the results, yield of soybean had little response to nitrogen. Phosp-
horus also gave no significant effect except in Chou-tun where 12 increment was obtained. Potash gave cansiderable increment of yield in Shintsu and Chou-tun, though though they were almost insignificant according to statistical analysis.
From this experiment the optimum N-P-K ratio for Soybean was proposed as follows.
