Bioinoculants also known assoil inoculants are agricultural amendments that are used as beneficialmicrobes to promote plant growth and their physiological activities. Bioinoculants are cost-effective and ecofriendly natural inputs providing alternate source of plant nutrients, thus increasing farm income by providing extra yields and reducing input cost also. The common bioinoculants are Rhizobium, Azotobacter, Acetobacter, Azolla, Azospirillum, and blue green algae. Bioinoculants increase crop yield by 20%–30%, replace chemical N andP by 25%, stimulate plant growth, activate soil biologically, restore natural fertility, and provide protection against drought and some soil-borne
