ALTERNATE SOD PRODUCTION SYSTEM FOR ZOYSIAGRASS
A limitation to distribution of some field-grown sod is the time required to produce a saleable product rooted sufficiently to retain its shape when removed from the ground. Research for a more efficient sod production process was examined using sod segments planted at a 1:100 plant:planting area ratio in an aboveground soilless, root-restricting system. Combinations of 3 growth media, 2 rooting stimulants, and 2 fertilizers each at 2 rates were evaluated to determine the most rapid and optimal sod development for zoysiagrass. Treatments were rated weekly for percent cover, rate of stolon development, and rooting. Although treatments with rooting stimulants generally scored higher than other treatments for rooting and percent cover, these differences were not consistently significantly different from week to week. No significant differences occurred among treatments for stolon development ratings. After 16 weeks of growth, sod strength was greatest when the growth medium was a peat and vermiculite mixture.
