Integrated nutrient management in cowpea with the application of microbial inoculants

Indian livestock sector is one of the largest in the world and fodder is vital component of profitable animal production. Legumes are one of the predominant crops of mixed crop-livestock systems providing highly nutritious fodder as well as contributing soil fertility. Nevertheless, the fodder production and quality in the country is not adequate to meet out the prerequisite of growing livestock population. Optimum nutrition is thus required for getting the maximum forage yield and quality. Nutrient Management is propounded as a promising strategy for addressing such challenges. Microbial inoculants being an important component of integrated nutrient management are eco-friendly and economical sources of nutrient. The benefit of combining organic and inorganic sources of nutrients in integrated nutrient management has proved superior to the use of each component individually. Thus, the present review will feature the need of integrated nutrient management, plant growth promoting rhizobacteria as microbial inoculants, role of microbial inoculants in integrated nutrient management of various leguminous crops and emerging examples of integrated nutrient management in cowpea. The realization attained from literature assessed herein will further help to understand the role of microbial inoculants in integrated nutrient management.
