Abstract
（一）本試驗之目的，在探求大豆最適當之栽培密度與施肥量。試驗始於民國57年夏作，終於59年夏作，共計進行五次，試驗地點在苗栗農工職校農場，試地爲砂壤土（PH爲6.5-6.8），肥力中等，其前作物皆爲水稻。
The objectives of this experiment are to investigate the effect of spacing and rate of fertilization on grain yield and agronomic charaters of soybeans.A4×3 factorial experiment design, with four spacings, i.e: d1 (40.5×l0cm, 247,000 phants/ha), d2(30×l0cm, 333,330 phants/ha), d3 (27×l3.Scm, 247,310 phants/ha) , and d4 (22.S/22.Scm, 197,510 phantsf/ha), and with three rates of fertilization, i.e: f1 (20-80-60 kg/ha), f2 (40-120-80 kg/ha), and f3 (80-160-100 kg/ha), are used. Agronomic charaters studied were: grain yield per plot, plant height, no. of main stem nodes, no. of pods, seed weight per plant, and weight per 100 seeds. The experiment repeated five times was begun in Summer (2nd crop) 1968 at the experimental farm of Miao-Li Agriculture & Vocational School, and ended in Summer 1970. The field is of sandy-loam soil with medium fertility, and with rice plant was the previous crop.
