The main objective of this study was to find the best mixture (growth media) for planting tomato nursery by mixing sand, peatmoss, and vermiculite. The mixtures were devided to three groups (sand + peatmoss), (sand + vermiculite), and (sand + peatmoss + vermiculite). Each group contains different ratio of sand and other component. Also, one sample was (40% petmoss + 60% vermiculite) as a control. Laboratory experiments were conducted to quantify real density (g/cm3), bulck density (g/cm3), hydraulic conductivity (cm/min), total porosity (%), and water holding capacity (g/g) as affected by different mixtures. The tomato nursery was planted into trays in greenhouse. The results show that in the media of ''sand + peatmoss'' increased sand ratio gave an increase in total porosity and a decrease in water holding capacity. At mixtures of ''sand + vermiculite'', the total porosity decreased with increase in sand ratio and water holding capacity decreased with an increase in sand ratio. The highest values of total porosity and water holding capacity were at mixture of (70% peatmoss + 30% sand). Also, the highest growth parameter of nursery as seedling weight and length was obtained with the same mixture.
