Indian Pennyworth (Centella asiatica L. Urban) Growth and Production to Phosphorus Fertilization in High Altitude

Abstract

The experiment was executed to find out the influence of phosphorus fertilization to the growth and production of indian pennyworth (Centella asiatica L. Urban) in the high altitude. This experiment was carried out at Gunung Putri experimental station Balittro, Cipanas, Cianjur in October 2008 until April 2009. The treatment was arranged in a Completely Randomized Design (CDR) consisted of single factor with 5 replications. The factor was P2O5 fertilization 0, 30, 60, 90, and 120 kg P2O5/ha. The results of experiment showed that P2O5 fertilizer significantly increased the total leaves number, leaves length, the total flower numbers, leaves thickness of mother plant and production components at 6 month after planting. The highest production (1.34 dry weight ton/ha) was found on 60 kg P2O5/ha. The optimum dosage to improved production of indian pennyworth in high altitude was 63.51 ± 2 kg P2O5/ha.
