Abstract: To investigate effects of different fertilizer levels and planting densities on yield and main agronomic characters, 12 treatments including fertilizer treatments as the main plot and density treatments as the secondary plot were carried out on the material of vegetable soybean ‘Zhexian No.9’ by using split plot design. The results indicated that yield had significant differences under different fertilizer levels and plant densities. Plant height, branch number, effective pod numbers and yield had significant differences under different fertilizer levels. Effective pod numbers and yield had extremely significant differences under different planting densities. Different fertilizer levels and planting densities influenced yield by effective pod number. Yield increased with the increase of fertilizer level, but there was no significant difference between the high level and the middle level. Low planting density could increase the productivity per plant, but reduced the population yield. For the economic and ecological benefit, the suitable cultivation measures of vegetable soybean ‘Zhexian No.9’ were fertilizer level of N 160-180 kg·hm-2, P2O5 90-110 kg·hm-2, K2O 90-110 kg·hm-2 and the density of 18-22 ×104 plants·hm-2. The results would provide theoretical basis for high yield and fine quality cultivation measures of vegetable soybean ‘Zhexian No. 9’.
