Abstract
The goal of this study aimed to determine how effectively microorganisms affected the growth and nutrient contents of tomato transplants. There were two treatments: (1) with effective microorganism (EM) treatment; and (2) without effective microorganism treatment–control. The height of tomato transplants was higher in the control treatment compared to the EM treatment. The stem diameters of tomato transplants were larger with EM treatment compared to the control variant. The nutrient content of tomato leaves was very good. The contents of nitrates, N, P, K, Ca, and Mg were higher with EM treatment compared to the control treatment.
