<![CDATA[Chili peper (Capsicum annuum L.) var. Prabu was grown with polyethylene mulched and drip irrigation system on Andosol Sukamantri soil with low pH (4.5), low C-Organic (1.79%), low N-total (0.18%), high K content (0.76 me/100 g), and very high soil P2O5 concentration (190 ppm) to optimise fertilizer rate for drip irrigated and polyethylene mulched crop management system. This research was conducted from March - July 2004 at Danasworo Hydrogarden Ciapus Bogor. This research was arranged in Randomized Completely Block Design with four levels of fertilizer rate (0=control; 1x recommendation rate =151 kg N/ha, 69 kg P2O5/ha, 120 kg K2O/ha; 2x recommendation rate = 302 kg N/ha, 138 kg P2O5/ha, 240 kg K2O/ha; 3x recommendation rate = 453 kg N/ha, 207 kg P2O5/ha, 360 kg K2O/ha). Hundred percent of P, 50% N and K were applied pre-plant and 50% N and K were fertigated 10 times. The result showed that plant height and plant dry weight increased linearly with fertilizer application from 0 to 3x recommendation rate. Total marketable yield was quadratically increased with fertilizer application from 0 to 3x recommendation rate. Base on total marketable yield, optimum recommendation rate for chili with drip and polyethylene mulch were 237.07 Kg N/ha, 108.33 Kg P2O5/ha, and 188.4 Kg K2O/ha. Key words : Chili, fertilizer, drip irrigation, polyethylene mulch, fertigation]]>
