 ABSTRACT

An experiment was conducted to study the effect of growing media depth of Chrysanthemum (Dendranthema grandiflora Tzvelev) cv. Prof. Harris 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 376.40 cm2 and highest leaf area of 463.07cm2 respectively. G5 recorded the highest mean for root number(30.61), flower diameter (7.32cm),  self life (36.69 days) and vase life (20.09 days) of flower. Media depth D3 recorded the highest mean of 37.09 for root number. On the otherhand, D3 found the maximum floral diameter (7.10cm), shelf life (38.86 days) and vase life (20.28 days) of the flower. Among the growing media and depth, the highest mean for fresh weight of flowers (5.29g) was recorded for G5 and 5.14g in D3. The highest mean for dry weight of flowers (4.27g) was recorded for G5, at par with G3 (4.09g).  The highest chlorophyll content (3.09mg g-1 FW) was recorded for growing media G5 and 3.37mg g-1 FW in D3. G5 (91.11%) and D3 (90.36%) recorded the highest moisture content for growing media and media depth respectively.
