An experiment was conducted to study the effect of growing media depth on gerbera (Gerbera jamesonii Bolus) cv. Red Gem for Rooftop Gardening during 2016. The experiment was laid out in two-factor completely randomised block design comprising of five growing medias having different components by volume at three different depths, viz. D1:10 cm, D2:20 cm and D3: 30cm depths. The media compositions were G1: soil + sand + coco peat + vermicompost (1:1:2:2), G2: sand + coco peat + vermicompost (1:2:2), G3: sand + coco peat + vermicompost + vermiculite (1:2:2:0.5), G4: sand + coco peat + vermicompost + perlite (1:2:2:0.5) and G5: sand + coco peat + vermicompost + vermiculite + perlite (1:2:2:0.25:0.25). Among the growing media and depth, G5 and D3 recorded the highest mean leaf area of 2785.69 cm2 and highest leaf area of 3452.17cm2 respectively. G5 recorded the highest mean for root number (202.33), flower diameter (8.55cm), self-life (15.64 days) and vase life (7.90 days) of flower. Media depth D3 recorded the highest mean of 245.13 for root number. On the other hand, D3 found the maximum floral diameter (9.80cm), shelf life (17.29 days) and vase life (8.73 days) of the flower. Among the growing media and depth, the highest mean for fresh weight of flowers (11.18g) was recorded for G5 and 12.64g in D3. The highest mean for dry weight of flowers (4.02g) was recorded for G5. The highest chlorophyll content (1.48mg g-1 FW) was recorded for growing media G5 and 1.82mg g-1 FW in D3. G5 (82.43%) and D3 (83.45%) recorded the highest moisture content for growing media and media depth respectively.
