Abstract: Soybean[Glycine max（Linn.） Merr.] variety Zhongdou 4601 was used as experimental material, a two-factor randomized block experiment was conducted to study the effects of fertilizer amount and planting density on the yield and agronomic traits of Zhongdou 4601. The results showed that the fertilization amount and planting density had significant effects on the yield of Zhongdou 4601. The difference between different fertilization treatments reached a very significant level. The interaction between fertilization amount and planting density had no effect on the yield of Zhongdou 4601. At a planting density of 330 000.0 plants/hm² to 660 000.0 plants/hm²,the yield of Zhongdou 4601 decreased with the increase of planting density. The number of main stems, effective branches, number of pods per plant, number of seeds per plant, and seeds weight per plant all decreased with increasing planting density. In Jingmen city, the yield of Zhongdou 4601 with 300 kg/hm² ternary compound fertilizer as base fertilizer was the highest when the planting density was 330 000.0 plants/hm².
