This experiment was carried out to study the effects of nitrogen concentration of cultural solution, Rhizobium inoculation, and planting density on the growth and yield of soybean cultivars, Hwanggeumkong, Jangbaegkong, Paldalkong, Clark, and non-nodulation isoline of Clark. Rhizobium inoculation increased the stem length, particularly in Hwanggeumkong, Jangbaegkong, and decreased it significantly in non-nodulation Clark. Stem length was increased by the increase in nitrogen fertilization by the 195ppm level and decreased by the increase in plant population density. Rhizobium inoculation also increased the shoot dry weight, but significantly decreased it in non-nodulation Clark. As nitrogen concentration in the cultural solution increased the shoot dry weight decreased in Jangbaegkong and paldalkong. However, the shoot dry weight was decreased by the increase in plant population density. Rhizobium inoculation and the increase in nitrogen concentration of cultural solution increased the ratio of shoot dry weight to root weight. The Rhizobium inoculation and the increase in nitrogen concentration of cultural solution increased the grain yield per pot in Hwanggeumkong and paldolkong, While non-nodulating Clark showed significant decrease in grain yield. Grain yield per pot was also increased by the increase of plant population density. Grain yield was significantly correlated with shoot dry weight, nodule number, and nitrogen content of the soybean plants. The correlation between nitrogen contents of the soybean plants and stem length, shoot dry weight, and nodulation was significant. The allantoin-N content in stem was also significantly correlated with nodulation.
