The thickness of a root zone is still a basis for football field constructors for good field performance along with saving root zone material. This research is a column pot experiment and placed in an open space to know the thickness of the root zone that is acceptable with the variable warm season grasses growth. The root zone used was a mixture of loamy sand, 75% sand, 10% soil, and 15% compost with a thickness of 15, 20, 25, and 30 cm. The grasses used were Zoysia japonica, Zoysia matrella, and Paspalum vaginatum and planted with sprigging, maintenance of watering, fertilization, and manual weed control. Harvesting was done after the plant is 34 weeks after planting. The results showed that the thickness of the root zone 25 and 30 cm had the same results on shoot density, time to 100% ground coverage, recovery rate from damage, plant height, clipping weight, root length, plant fresh weight, and root dry weight, and efficiency of use air. In all thicknesses of the root zone, Paspalum vaginatum had the highest yield on shoot density, 100% ground coverage, recovery power, plant height, cutting weight, root volume, leaf fresh and dry weight, root fresh and dry weight, and air efficiency.
