With the growing human population worldwide, innovative agricultural development is needed to meet food security needs. However, this has inadvertently led problematic irrigation practices and overuse of agrochemicals. Such can exacerbate soil salinization, which prevents plant growth. As a progressively widespread escalating problem, salinization poses major threat global security.

Salinity represents a major environmental factor limiting plant growth and productivity. In order to better understand the effects of arbuscular mycorrhizal fungus Claroideoglomus etunicatum Indole-3-acetic acid (IAA) on chemical composition vetiver grass (Vetiveria zizanioides) under salt stress, factorial experiment was conducted in completely randomized design with three replications. The included four NaCl levels (0, 8, 16, 24 decisiemens per meter (dS/m)) treatments (no amendment application, application IAA, C. etunicatum, interaction IAA etunicatum) results showed that addition sodium chloride increased concentration proline activities catalase, peroxidase, superoxide dismutase enzymes. regulator significantly fresh dry weight (101%) shoots, roots, macro- micro-elements shoots salinity condition (99.82% phosphorus; 9.79% Iron). mycorrhiza auxin reduced general, roots stress conditions can improve increase some nutrients shoots.
