유기질비료 처리가 콩 생육 특성에 미치는 영향

초록

Recent concerns over the environmental repercussions of excessive chemical fertilizer use have led to growing interest in the utilization of organic fertilizers for crop cultivation. However, the effects of organic and inorganic fertilizers on soybean plant growth remain unclear. Therefore, this study aimed to investigate the effects of organic fertilizer application on the shoot, root, and yield-related traits of soybean plants. The experiment was conducted in both the ‘Gunwi’ and ‘Gyeongsan’ regions, with the organic fertilization treatment being compared with a control group. Our results revealed that there were no significant differences in shoot traits between the organic fertilization treatment and the control. However, compared with the control, the organic fertilizer treatment led to a small increase in stem width and branch number. On the other hand, there was no discernible difference between treatments for any root traits, including total root length, surface area, branch number, and average root diameter. Correlation analysis indicated that plant height had the highest positive correlation (r2 = 0.6***) with yield, followed by the total seed number per plant (r2 = 0.41***). In conclusion, the use of organic fertilizers did not result in a significant difference in shoot and root traits compared to the control group. As a result, our experiment found no increase in yield with organic fertilizer application compared with the control. As the experimental field already contained sufficient organic matter, the additional supply of organic and inorganic fertilizers from external sources had no significant effect on the yield.
