Abstract

. Tedjasarwana, R. and S. Wuryaningsih. 2009. Cultivars and Fertilizer Formulae on the Growthof Anthurium Cut Flower. Anthurium cut flower (Anthurium andraeanum Lind.) has spesific flower form like hatconsist of spathe and spadix with variation on spathe color, and has long vaselife. The objectives of this researchwere to find out fertilizer formula and cultivars of Anthurium to increase the productivity of Anthurium cut flower.The experiment was carried out in a Screenhouse of Segunung Field Trial at Indonesian Ornamental Crops ResearchInstitute (IOCRI) from January to December 2006 at 1,100 m asl. Factorial design with 3 replications was used.The first factor was 2 cultivars of Anthurium cut flower consist of Tropical and Avo Orange. The second factor wasfertilizer formula: (1) Anthura as a control, (2) IOCRI 1, (3) IOCRI 2, (4) IOCRI 3, and (5) IOCRI 4. The resultsshowed that chlorophyl number, length and diameter of spadix, also flower stalk diameter of Tropical variety washigher than Avo Orange, i.e. 63.96 unit; 5.81; 6.77 cm, and 4.86 mm, respectively. On the other hand, Avo Orangeshowed faster flower initiation with flower stalk length and flower production higher than Tropical, i.e. 45.19 days;46.27 cm, and 19.13 flower stalk/plot respectively. Fertilizer IOCRI 4 showed fastest flower initiation (49.36 days)and fertilizer IOCRI 3 indicated the highest on flower production (18.0 flower stalk/plot)
