Azospirillum biofertilizer technology for different crops of Andhra pradesh

Abstract

In Andhra Pradesh, recent statistical data shows that there is 10.1 million ha cultivated area, constituting 37% of states total geographical area. The important crops are rice, cotton, maize, sunflower, chilli and sorghum. With a cropping intensity of 122%, food grains production is 13.4 million tonnes, suggested interventions for natural resource management for agriculture in the state. Important resource management is nutrient management; such as use of biofertilizers. Among the biofertilizers, nitrogen fixers play an important role. Azospirillumbiofertilizer is a promising nitrogenous biofertilizers, which not only increases productivity but also reduces the cost of cultivation and improve soil health. Azospirillum is a Gram-negative, microaerophilic, non-fermentative and nitrogen-fixing bacterial genus from the family of Rhodospirillaceae. Azospirillum bacteria can promote plant growth through nitrogen fixation
