A one year field experiment was conducted to elucidate the effectiveness of different soil organic amendments and chemical fertilizers on tuberose at the Floriculture Research Field, Bangladesh Agricultural Research Institute, Gazipur from March, 2014 to May 2015. The experiment consisted of nine treatments namely: T 1 = Farmyard manure (5 t/ha) + ½ (Recommended doses of fertilizer (RDF) that is N=150 kg, P=30 kg, K=100 kg, S=20 kg, B=1 kg, Zn=1 kg per hectare) T 2 = Farmyard manure (10 t/ha) + ½ RDF, T 3 = Poultry refuse (5 t/ha) + ½ RDF, T 4 = Poultry refuse (10 t/ha) + ½ RDF, T 5 = Vermicompost (5 t/ha) + ½ RDF, T 6 = Vermicompost (10 t/ha) + ½ RDF, T 7 = Bokashi (3 t/ha) + ½ RDF, T 8 = Bokashi (5 t/ha) + ½ RDF and T 9 = Control (Recommended doses of fertilizer (RDF). The experiment was conducted in Randomized Block Design (RCBD) with three replications. The results showed that application of organic amendments and fertilizer had significant variations on most of the parameters. The maximum vase life of flower, number of bulb/hill, number of bulblet/hill, bulb diameter, bulb weight, 10 bulblet weight, yield of bulb and yield of bulblet were obtained with the use of 10 t/ha vermicompost along with 50 percent recommended dose of fertilizer (RDF). In conclusion, application of 10 t/ha vermicompost along with fertilizers at a rat of N=75 kg, P=15 kg, K=50 kg, S=10 kg, B=0.5 kg, Zn=0.5 kg per hectare is recommended for durable flower and bulb production of tuberose.
