Yeast is used asbio-fertilizer in agriculture for the biological activity and protection for animal, human and the environment. Plant growth promoting by yeast enhanced the plant root and growth development. The variable nutritional and hormonal stability, producing plant growth regulators, solubilizing nutrients in soil by yeast can promote plant growth. In the current research the analysis of plant growth enhancement, phytochemical constituent and the antioxidant activity of Sorghum bicolor and Arachis hypogeal was done.
