Effect of Azospirillum on fodder production in the semi‐arid region of South India

摘要

Productivity of the tropical and subtropical grazing lands is generally very low.Chemical fertilizers are expensive and ecologically not desirable.Greater emphasis is now laid on the application of biofertilizers to increase the fodder production.Nitrogen fixing bacteria have the potential to reduce nitrogen fertilizer requirements in many agricultural areas.Yield increase after inoculation with Azospirillum have been recorded in many places throughout the world.A zospirillum lipo f erum inoculation showed higher green forage yield than A zospirillum brasilense.In the present investigation A zosp irillum lipo f erum strain (ICM 1001) was used to increase the productivity of five fodder grasses.
