The research was conducted in the greenhouse of the Plant Production Techniques Department, Al-Mussaib Technical College for the autumn season 2019-2020. To study the effect of bacterial fertilizers and organic medium on the growth and flowering of Ranunculus asiaticus, Red cultivar in pots 22 cm in diameter, The research included the effect of two factors, the first factor the bio fertilizers bacterial, with four levels (without the bacterial vaccine, Bacillus subtillus, Azospirillium brasilences, Azospirillium brasilences +Bacillus subtillus) and which it were symbolized by (B0, B1, B2, B3) and the second factor, the organic medium that included (River soil + peat moss at a ratio of (2: 1), River soil + 3%, decomposed horse waste, River soil+ 3% residues from decomposing fungi (mushrooms), Agaricus bisporus, River soil + 5% decomposed horse waste, River+ 5% residues of the decomposing fungus (Agaricus bisporus) and which it were symbolized by (A0, A1, A2, A3, A4). factor experiment was conducted according to Completely Randomized Design ( C.R.D ) and by three replicates and each replicate contains (20 treatments), The averages were compared according to the L.S.D test under the 5% probability level .The results of this study can be summarized as follows: The treatment with bio fertilizers bacterial resulted in a significant increase in all the studied traits. where the treatment of B3 (mixture) recorded the highest average in plant height, leaf area, percentage of carbohydrates in leaves, number of flowers, flower diameter, vase life, anthocyanin pigment, the results were as follows: 44.80 cm, 1293 cm 2,12.87 flower.plant -1,13.62%, 63.19 mm, 14.20 days, 2.47 mg.100 g-1.The results showed the excelled of the organic medium treatments, where the A3 treatment (River soil + 5% decomposed horse waste) recorded the highest average for all the studied traits, plant height, Leaf area, percentage of carbohydrates in leaves, number of flowers, flower diameter, vase life, anthocyanin pigment and the results were as follows: 44.88 cm, 14.59 cm 2,14.23%, 13.38 flowers.plant-1, 66.08 mm, 15.66 days, 2.75 mg.100 g-1.The results of the bi-interaction between the biofertilizer bacterial and the organic medium showed significantly excelled in all the studied traits. where the A3B3 treatment excelled in the plant height, Leaf area, percentage of carbohydrates in the leaves, number of flowers, flower diameter, flowering age, anthocyanin stain and the results were as follows: 53.17 cm, 82.0 cm, 1691 cm2, 15.88%, 17.17 flowers.plant-1, 72.14 mm, 3.51 mg. 100 g dry weight.
