Safed Musli (Chlorophytum borivilianum) is sold worldwide with a total demand of 50,000mt y-1; however the global supply is limited to 5,000 mt y-1. Tubers of Safed Musli (SM)contain saponin compound which can induces sexual desire and widely used in Ayurveda medicines. A field and glasshouse/laboratory was conducted at FELDA Herbal Farm, Lanchang, Pahang and UPM, respectively. The objectives of this study were to determine the effects of the rhizobacteria and vermicompost (earthworms) on (i) root development and tuber yield, (ii) saponin concentration and content in SM. The field and glasshouse study will be laid out in RCBD with 5 replications (8 treatments, single, or mixed treatments with inorganic-N,uninoculated, UPMB-10, UPMB-13 and vermicompost). The laboratory study will be done to isolate phytohormone-producing rhizobacteria (eg. IAA) for SM roots using HPLC and "N techniques will be used to determine N2 fixation by the rhizobacte ria.
