Pengaruh Pupuk Organik dan Intensitas Naungan terhadap Pertumbuhan Bibit Kopi Robusta (Coffee canephora Pierre ex Froehner)

Abstract

The experiment was aimed at study the effect of organic fertilizer and shading intensity on the growth of Robusta coffee seedling. Seven month old seedling of hybrid variety of BP 42 and BP 358 crossing were used in the experiment was conducted at Cikabayan Experimental Station Bogor Agricultural University, fiom July 2000 to January 2001. The experiment was arranged in split plot design with three replications. The main plot was shading intensity consisted of 25% (N,), 50% (Nd, 75% (N3 and 100% (NJ shade. The sub plot was organic fertilizer consisting of 4 g EMAS + K dosage of inorganic fertilizer (d. i.j (PI), 4 ml EM 4 + K d. i f (Pd, 4 g OST + K d. if(P&, 20 ml Soils Plus + K d. i f (PS and I dosage of inorganic fertilizer (P5). Organic fertilizers amted growth, as shown by height and stem diameter of seedling at the early period of experimbnt and shoot biomass at the end of experiment compared to one dosage of inorganic fertilizer. Shading intensity and its interaction with organic fertilizer didn't give any signf~ant effect on all variable during the experiment.
