Objective of this research was to determine the effect of application rate of dolomite in root media containing micronutrient mixes on growth of marigold 'Orange boy' in plug trays. To achieve this, three granular micronutrient mixes such as HF 1, MF 2, and MF 3 were produced and incorporated into three root media, peatmoss+composted pine bark (1:1, v/v, PB), peatmoss+composted rice-hull (1:1, v/v, PR), and peatmoss+composted saw-dust (1:1, v/v, PS), with a rate of $0.3g{cdot}L^{-1}$. Elevated application rate of dolomite in PB medium containing MF 1 decreased crop growth at 35 days after sowing with the highest fresh and dry weight in the control treatment of dolomite. The treatments of 3.0 and $6.0g{cdot}L^{-1}$ of dolomite in PB medium containing MF 2 produced 0.133g of dry weight and 0.686g of fresh weight, respectively, which were the highest among treatments of dolomite. But the treatments of 3.0 and $6.0g{cdot}L^{-1}$ of dolomite in PB medium containing MF 3 produced the highest fresh and dry weight, respectively. Elevated application rate of dolomite in PR medium containing MF 1, 2, and 3 resulted in decrease of fresh an dry weight. The relative growth suppression induced by elevated application rate of dolomite was more severe when MF 3 were incorporated than MF 1 and 2. The treatments of 3.0 and $6.0g{cdot}L^{-1}$ of dolomite in PS medium containing MF 1 and 3 showed good growth, but elevated application rate of dolomite in PS medium containing MF 2 and control resulted in increase of dry and fresh weight. These results indicated that the application rate of dolomite should be adjusted by kinds of root media and micronutrient mixes.
