Rice based cropping system is a major cropping system practiced in India, which includes the rotation of crops involving cereals, pulses, oil seeds, cotton, sugarcane, green manures and vegetables. The present study reports major rice based cropping systems from different parts of India ranging from rice-rice-rice to rice followed by other crops. Different rice based crop rotations were evaluated at 13 locations to economize the nutrient recommendation, enhance nutrient use efficiency, soil health and sustain productivity. The results showed that rice-maize rotation produced the highest rice equivalent yield (10.2 t/ha) and net monetary returns (Rs. 59,110/ha). Conventional tilled rice-rice system produced the highest system productivity compared to other tillage management practices. Similarly, Rice-linseed system also produced the highest system productivity under conventional tilled system than either minimum tilled or zero tilled based management practices. It is concluded that reduced tillage negatively affected the rice based cropping system than conventional tillage practices.
