Effective microorganisms (EM) comprise a mixture of live natural cultures of microorganisms isolated from fertile soils that are used to improve crop production. The purpose was to assess the influence of EM on the growth and nutrient content of leaf celery transplants. Two treatments were compared: 1) EM treatment comprised of seed soaking in EM 1:500 solution, sowing in EM treated peat and watering the plants weekly with EM solution. 2) Control treatment included similar treatments with water. Leaf celery transplants grown with EM were significantly shorter and had thicker stems than those grown without EM. The contents of nitrogen, phosphorus, potassium and calcium increased in transplants grown with EM compared to those grown without EM. The contents of nitrates and magnesium did not show statistically significant differences. Conclusion: EM improves the growth and increases nitrogen, phosphorus, potassium and calcium contents of leaf celery transplants.
