【 摘 要 】

The nutrient availability in peat soils is low. The initial analysis of peat soils in Rawa Pening showed acidity of 5.07; Carbon (C) organic of 18.18 %; total Nitrogen (N) of 1.6; Phosphate (P) of 1.63 ppm; Kalium (K) of 13.29 ppm; whereas Cation Exchange Capacity (CEC) level was high (85.94 ppm). The application of Dolomiteor Zeolite amendments of 2.5 t/ha for 3 weeks incubation showed to increase the soil acidity to 6.55 and 6.7, respectively. Singawalang (Petiveria Alleaceae.L) is an herbaceous, annual plant with medicinal properties. P.alleaceae was shown to contain astilbin, benzal dehyde, and coumarin phytochemicals with anti-tumor and/or anti-cancer properties. This study aimed to improve the nutrients absorption ability of P.alleaceae with Dolomite, Zeolite and NPK fertilization. P.alleaceae were plant polybag using peat soils medium by Completely Random Design (CRD). Zeolite, Dolomite (2.5 tons/ha) and NPK Fertilizer 15:15:15 at a dose of (0;1.5;3;4.5) g/plant were applied. The results showed that all treatments failed to improve the growth and uptake parameters of N, P, K. Except for the total chlorophyll lamount. Zeolite with NPK showed higher increase of the total chlorophyll amount compared to Dolomite with NPK.
