Abstract: | Amaranth (Amaranthus sp.), kangkung (Ipomoea aquatica L.), eggplant (Solanum melongena L), chili (Capsicum annuum L.), tomato (Lycopersicon esculentum Mill), green bean (Phaseolus vulgaris L.), and yard -long bean (Vigna unguiculata L.) were grown on Ultisols soil of Nanggung with low pH (5.2), low organic C (1.70%), very low total N (0.21%), low K content (0.33 mellOO g), but high soil P20 S concentration (10.8 ppm) to optimize P rate application. Treatments were Prate: 0,45, 90, 135 and 180 kg P205/ha or equal to 0, 125, 250, 375 and 500 kg SP36 (36% P20s)/ha. Treatments were arranged in Randomized Completely Block design with three replications. In the level of soil P concentration of 10.8 ppm (Bray-I) of Ultisols, application of P fertilizer up 180 kg P205/ha linearly increased plant height of kangkung, eggplant, chili, tomato, yard-long bean and green bean and linearly increased yield of amaranth, kangkung, eggplant, chili, tomato and green bean. To achieve optimum P fertilizer rate, the range of P rate application needs to be increased. |
