India produces 24.8% of world rice by standing first in area (43.9 million ha) and second in production (106.5 million tons) globally. Rice plays vital role in Indian food security as it is staple food for two thirds of Indians supplying 33% of food energy.Rice productivity and production are to be increased to meet the demands of increasing population. Indian rice farmers are constrained by escalating farming cost and depleting income. The rice productivity in India is low (2.4 t/ ha) due to wide range of environmental conditions and ways it is grown and the biological and physical constraints that prevail. Among biological constraints weeds are major causing yield losses of 10 to 100% depending on method of rice establishment, associated weeds, cultural practices adopted, environmental and other associated factors (Rao and Nagamani 2010, Rao et al. 2015). Thus any effort involving improvement in food grain production to meet current and future food demands and double the farmers’ income must involve rice and weed management. The objective of the present analysis is to assess weed management role in attaining higher crop production and to double the income of rice farmers in India.
