The Effect of P2O5 Fertilizer, Zeolite, and Volcanic Soil Media from Different Altitudes on the Soil Mineral, Growth, Yield, and Asiaticoside Content of Centella asiatica L.

Centella asiatica is an herbal plant with many health benefits due to the content of asiaticoside compounds. Factors affecting are altitude, soil texture, and nutrient status. This research aimed identify effect zeolite, P2O5 fertilizer, media from different altitudes on C. asiatica. The was conducted in a greenhouse August 2017–June 2018. experimental design factorial, completely randomized three factors four replications. first factor that originated 100, 450, 900 m above sea level (asl), second dose fertilizer (0, 27, 54, 81 kg ha−1), third zeolite 3, 6 t ha−1). results showed applying minerals at all increased availability cation exchange capacity (CEC) by up 70%. novelty this study altitude asl, 54 ha−1, has loamy sand texture produces highest (3.61%) largest dry weight (19.24 g). These did not significantly differ those obtained 450 asl sandy loam (the most suitable for asiatica), 3.37% 19.87 g weight. concluded could develop giving it ha−1 fertilizer.
