Abstract

Productivity and quality of patchouli is influenced by environmental factors especially drought stress. This study a im i s to determine application of giant salvinia compost for resolving drought stress on patchouli . This study used a randomized block design and experiment with three replication arranged in fa c torial 3 x 4 . The first factor is percentage of drought stress 0% ( L 0 ), 40% ( L 1 ), and 80% ( L 2 ). The second factor is application of giant salvinia compost, topsoil 100% ( G 0 ), topsoil an d giant salvinia compost 1:1 ( G 1 ) , topsoil an d giant salvinia compost 2:1 (G 2 ) , and topsoil an d giant salvinia compost 3:1 (G 3 ) . The result showed that giant salvinia affected increasing on plant height, number of branch, the ratio of root-shoot dry weight, and patchouli oil content . Keywords: growth medium, patchouli oil content, soil moisture
