KAJIAN PENENTUAN KEBUTUHAN HARA FOSFOR ORGANIK DAN ANORGANIK PADA TANAMAN BAWANG MERAH (Allium ascalonicum L.) VARIETAS PHILIPINE

SAMSUL ARIFIN

Abstract


The research was conducted were studied at Tegalgondo research farm in Karangploso Malang at farm with; pH (H2O) = 6,9; pH (KCl) = 6,3; organic = 1,85 %; C organic = 1,07 %; N total = 0,17 %; C/N = 6; P Olsen = 12,92 mg kg-1; K = 1,78 me/100g, from November to December 2003. A factorial research using Randomized Block Design with three replicates was used. The treatments consisted of three levels of sort organic (no organik matter, azolla as a green manure 10 t/ hektar and dirt of chicken manure 10 t/ hektar) and dosage of phosphate fertilizer of four levels (45, 90, 135 and 180 kg/ hektar P2O5 (TSP)). The result to research show that need optimal phosphor of shallot varietes Philipine was dirt of chicken manure 10 t/hektar and 90 kg/hektar P2O5 (TSP).
