This review article consolidates more information with special reference to effect of legumes and green manures integration on rice based cropping systems of the Tropics both in normal soil as well as problem soils. The factors influencing the nitrogen dynamics in soil by addition of food legumes and green manures besides their influence on the rice production and productivity in lowland irrigated conditions are also briefly reviewed because nitrogen is the most limiting nutrient in rice production world wide and inclusion of legumes and green manures with their wider adaptability to different rice cultures and their ability to fix nitrogen offer high scope to increase and sustain productivity and income in rice based cropping systems.
