We investigated that the effect of new iron-supplement fertilizer TetsuRiki (Aichi Steel’s company) containing FeO as a main component on the growth and post-dormancy growth of Japanese lawn grass (Zoysia japonica Steud.) under the field conditions. Plants were supplied by ion-supplement application under three levels control (0 kg/m2), low (0.17 kg/m2), high (0.33 kg/m2). Plant height and dry matter weight of shoot were remarkably improved in parallel with the improvement of leaf SPAD value. And the number of budding was increased with adversely effecting post-dormancy recovery in spring. Iron and manganese concentrations in aboveground plant parts were higher in Fe application plots than control plots. However, the number of sprout in Fe application plots was no significant difference between control plots.
