Abstract: Arsenic Rice is the most important and extensively cultivated food crop, which provides half of the daily food for one of every three persons on the earth. In Asia alone, more than two billion people obtain 60 to 70 per cent of their energy intake from rice and its derivatives. The major rice growing areas are West Bengal, Andhra Pradesh, Odisha, Jharkhand and Tamil Nadu. Rice production in India is an important factor for food security. However, little is known about the sustainability of the current production systems, particularly systems with triple cropping under minimum practice. Among the various cropping systems, rice based cropping systems are the predominant systems in India. Managing the variability in soil nutrient supply that has resulted from intensive rice cropping is one of the challenges for sustaining and increasing rice yield in India. Site Specific Nutrient Management (SSNM) provides an approach for “feeding” rice with nutrients as needed. Researchers developed the SSNM approach in the mid-1990s and evaluated it from 1997 to 2000. SSNM was evaluated and promoted with farmers at about 20 locations in tropical and subtropical Asia..
