The role of fertilizer sources and water stress on the growth and yield sambiloto (Andrographis paniculata Ness.)

Abstract

Abstract Sambiloto is medicine plant that has great potential as base material of traditional medicine. The aim of the study was to examine the response of Sambiloto growth and yield to fertilizer and water stress. Factorial study with completely randomized design consisting of two treatment factors. The first factor is the kind of fertilizer, consist from without fertilizer treatment, chemical fertilizer, chicken manure, and azolla compost fertilizer. The second factor is available water. The result of research showed that fertilizer sources and water stress have effect to leaves amount, fresh weight of shoot, and dry weight of shoot, simultanously. Combination of treatments that gived the highest dry weight of shoot (simplicia) are chemical fertilizer on 100% of field capacity and azolla compost fertilizer on 100% of field capacity. The using of organic fertilizer (chicken manure and azolla compost fertilizer) can subtitute the using of chemical fertilizer. Water stress has happen to 50% of field capacity of available water and decrease result significantly to all variable except clorophyl amount and amount of pods.
