The study was conducted at the Teaching and Research Farm of Agricultural Faculty, University of Jambi, Indonesia, from April through to September 2019. The aim of this study was to investgate the effect of biostmulants and media compositons on the growth and yield of chili pepper during restricted soil water content. The study was arranged in a split plot design with 3 replicates (groups). Different types of biostmulants (Citorin[R], Hantu[R], and a control) were designated as main plot, whereas media compositons (2:2:1, 2:1:1, 1:2:1 and 1:1:2) made of soil+trichocompost+rice husk charcoal were employed as sub plot. At the tme of transplantng, soil water content was set to approximately 75% of field capacity to create stress conditons. The results showed that the proper choice of biostmulant and medium compositon could increase nutrient status, total sugar and chlorophyll contents, and reduce proline level in plants grown under restricted water availability. Citorin[R] applicaton on chili plants grown on organic media (soil+trichocompost+rice husk charcoal) with rato of 2:1:1 could be recommended to support plant growth and producton under drought stress conditons.
