Abstract :
As the world strives to reduce NPK fertilizer usage and increase the sustainability of its agriculture, it is facing a rapidly growing population, which will soon require more food than current agricultural methods can produce. In this scenario it is important to find means of improving yields that do not rely on the application of the chemicals alone. In view of persistent relatively high cost of fertilizer, the exploitation of integrated use of chemical fertilizers with biological fertilizers is an attractive strategy for developing sustainable agriculture production. Bio fertilizers coated chemical fertilizer ( Bio active Urea) and Bio organic Phosphate (BOP) has been prepared and their effect on the cost and yield of the crop has been studied .In comparison chemical DAP and BOP, BOP gave 23- 24% higher grain yield in wheat and maize and 15-40% higher biomass in wheat, maize and sorghum. In case of Bio active Urea the increase in yield was 18-20% as compared to normal Urea. The reduction in the cost of fertilizers was 40% in comparison to chemical fertilizers. The use of Bio Coated chemical fertilizers is currently gaining interest in Pakistan as cheap and safe alternate to chemical fertilizers without compromising the yield and quality of crops. During the last six months about 100,000 bags of bio coated urea has been utilized by the farmers. Results showed the significance of integrated use of Bio fertilizers and chemical fertilizers. As the farmer field results are very promising it is obvious that this technology can also work well in Sri Lanka.
