The present investigation entitled “Studies on the effect of different combinations of media and bio fertilizers on growth, flowering and cut flower yield of gerbera (gerbera jamsonii L.) cv. Natasha under protected conditions”. The whole experiment was arranged over 10 treatments consisting of five levels of media combinations, M1 - Red soil + Coco peat (1:1), M2 - Red soil + Vermicompost (1: 1), M3 - Red soil + Coco peat + Vermicompost (1:1:1), M4 - Red soil + Coco peat + Vermicompost (2:1:1) and M5 - Control (Red soil only) with two levels of bio fertilizers B1 - PSB (Phosphate Solubilizing Bacteria) and B2 - VAM (Vesicular Arbuscular Mycorrhiza). Interaction between different media combinations and bio fertilizers had significant influence on growth parameters and root parameters. M3 combination of media [Red soil + Coco peat + Vermicompost (1:1:1)] and B2 bio fertilizer, Vesicular Arbuscular mycorrhiza (VAM) registered significantly maximum plant height at first flower appearance (22.27 cm), plant height at flower harvesting stage (24.97 cm), wider plant spread at first flower appearance East - West direction (51.92 cm) and North - South direction (54.94 cm), higher plant spread at flower harvesting stage East - West direction (53.98 cm) and North – South direction (57.94 cm), more number of leaves per plant (37.29 cm), broader leaf area at final harvest (120.45 cm2), more number of roots per plant (60.29), highest length of the primary root (53.29 cm), maximum value of plant fresh weight (202.78 g) and highest root to shoot ratio value (0.93 %).
