PENGARUH DOSIS PUPUK MAJEMUK DAN INTERVAL PENYEMPROTAN PUPUK DAUN TERHADAP PERTUMBUHAN ANTHURIUM DAUN WAVE OF LOVE (Anthurium sp.)

The research aimed to find out about the influence of compound fertilizer through roots and leaves to the growth of wave of love leaf anthurium. There was interaction between the treatment of fertilizer dosage through roots and interval of leaf fertilizer spraying to the growth of wave of love leaf anthurium. Compound fertilizer could increase/fix the growth of wafe of love leaf anthurium, leaf fertilizer spraying could influence the growth of wafe of love leaf anthurium. The research was done at Lowokwaru sub-district Malang City, with 550m upper sea surface height. The research was started in September to December 2008. Tool used in this research was measurement glass, ruler, meter measurer, plastic, plastic pot, bamboo, dipper, sprayer, spidol, book, and writing tool. Material used was anthurium seed (wave of love), organic fertilizer, Decastar compound fertilizer (13:13:13), GrowMore leaf fertilizer, Apsha leveller, fungicide dithane insecticide Mipcsin. The research was done by Split Plot Design arranged in factorial with three repeats. Major box was spraying interval, consisted of three level, they were: I1: once in four days interval, I2: once in four days interval, I3: once in 12 days interval, while member box was Decastar compound fertilizer dosage, consisted of 4 levels, they were: DO: 0g/plant dosage, D1: 1,5g/plant dosage, D2: 3g/plant dosage, D3: 4,5 g/plant dosage. According to the research, there found that there was interaction between leaf fertilizer dosage and compound fertilizer dosage to the plant height, leaves amount. The best treatment was I3D2, I3D3, I1D2, I2D1, and I2D2. Combination of spraying with once in 12 days spraying and 3 g/plant dosage. Leaves fertilizer spraying dosage has unreal influence to the plant height, leaves amount, stem height, and leaf width. The treatment of compound fertilizer dosage has significant influence to the plant height, leaves amount, the leaf width, where D3 dosage (4,5 g/plant) has no difference with D2 (3 g/plant). Good fertilizer with 3 gram dosage per plant (D2)
