Current status of biofertilizers development, farmers acceptance,utilization and future perspective in Andhra Pradesh, India
Andhra Pradesh climate is generally hot and humid. The major role in determining the climate of the state is played by south west monsoons. Agriculture plays a pivotal role in the economy of the state. In recent years, indiscriminate use of chemical pesticides and fertilizers lead to increased cost of cultivation and environmental pollution. Due to, energy crisis and increased fertilizer cost have necessitated to use of cost effective organic sources of nutrients to maintain soil fertility, productivity and health for sustainable crop production. Use of organic manures and biofertilizers could offer a safe and best option for reduction of currently used agrichemicals. Beneficial microbes such as Rhizobium, associative and free living nitrogen-fixing bacteria, phosphate solubilizing bacteria, arbuscularmycorrhiza, and other beneficial fungi are considered as bio-fertilizers. The extensive research program on beneficial bacteria and fungi in our lab has resulted in the development of a wide range of biofertilizers, which satisfied the nutrient requirements of crops, suppression of diseases and increased the crop yields. Our experiments in the greenhouse and under field conditions showed that different crops responded positively to microbial inoculations.
