Preliminary study on the cultivation of four different species of mushroom (Genus Pleurotus) using dried vetiver grass (Vetiveria nemoralis) as substrate, was conducted during March 1994-January 1995 at Som Dej Pra Sri Nakarin Royal Garden, Huai Sai Royal Development Center, Petchaburi Province. They are Pleurotus sp. Florida (Hed Hang rom Kao), Pleurotus sp. from Hungary (Hed Nang Rom Hungary), Pleurotus sp. (Hed Bhuthan), and P. abalonus (Hed Pao Hu). Pasteurization and non-pasteurization methods were applied. Two formulae of the first method used for substrate preparation were : Coarse grinded vetiver grass mixed with rice bran, sugar, magnesium sulphate (100:4 kg:2 kg:0.02 kg) and water as needed (m/c 60-65 percent) and cut vetiver grass composted with 7 percent w/w rice bran. These mixture were bagged, pasteurized and spawned. It was observed that the first formular produced higher yield in every species. The second method was non pasteurization by which cut soaked vetiver grass was bagged and spawned simultaneously. Fruiting bodies were observed only on two bushroom species Pleurotus sp. Florida and Pleurotus sp. from Hungary.
