Objective of this research was to determine the effect of application level of fused superphosphate (FSPP) in root media containing granular micronutrient fertilizers (MF) on growth of marigold 'Orange boy' in plug culture. To achieve this, three granular micronutrient mixes such as MF 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), at a rate of $0.3g{cdot}L^{-1}$. Elevated application level of FSPP in PS medium containing each of MF resulted in increase of plant growth such as plant height, plant width, stem diameter, fresh weight and dry weight at 35days after sowing. The dry weight in the treatment of MF 1, MF 2, MF 3, and control fertilized with $9.0g{cdot}L^{-1}$ of FSPP were 0.066g, 0.103g, 0.077g, and 0.095g per plant, respectively. These results indicated that each of MF affected marigold plug seedlings differently. The application level of FSPP resulted in the heaviest fresh and dry weight in PR medium were $9.0g{cdot}L^{-1}$ in MF 1, $3.0g{cdot}L^{-1}$ in MF 2, $9.0g{cdot}L^{-1}$ in MF 3, and $6.0g{cdot}L^{-1}$ in control. Elevated application level of FSPP in PB medium containing each of the micronutrient mix increased fresh and dry weight. The general trends in response of plant growth to elevated FSPP were linear and quadratic. The dry weight in the treatment of MF 1, MF 2, MF 3, and control fertilized with $9.0g{cdot}L^{-1}$ of FSPP in PB medium were 0.131g, 0.104g, 0.137g, and 0.111g per plant at 35days after sowing. These results indicated that MF 1 and MF 3 performed better than MF 2 and control treatments in growth of marigold plug seedlings.
