Relevance of the research topic Curcuminoids are main bioactive ingredients of turmeric Curcuma longa L. As a result of the recent growing demand for these compounds for pharmaceutical industrial application the development of high quality turmeric production has become an urgent issue. To solve the problem amendments in agricultural practices post-harvesting processing techniques and biotechnological methods have been highlighted. From another perspective reducing chemical fertilizer while remaining crop yield is a trend of modern environmental friendly agronomy these years. Developing microbial inoculations from effective microorganisms for particular agricultural plants has thus been considered a practical focus. On the other hand several rhizosphere soil microorganisms have been reported to play important roles in promoting biosynthesis of secondary metabolites including curcuminoids. The entitled Study on rhizosphere microbial communities of medicinal plant Curcuma longa L. to enhance turmeric yield and quality was conducted to apply microbiology in sustainable development of agricultural productivity in .
