Weed management role in increasing crop yield and doubling rice farmers? income in India - An analysis uri icon

abstract

  • India produces 24.8% of world rice by standing first inarea (43.9 million ha) and second in production (106.5 milliontons) globally. Rice plays vital role in Indian food security as itis staple food for two thirds of Indians supplying 33% of foodenergy.Rice productivity and production are to be increasedto meet the demands of increasing population. Indian ricefarmers are constrained by escalating farming cost anddepleting income. The rice productivity in India is low (2.4 t/ha) due to wide range of environmental conditions and ways itis grown and the biological and physical constraints thatprevail. Among biological constraints weeds are majorcausing yield losses of 10 to 100% depending on method ofrice establishment, associated weeds, cultural practicesadopted, environmental and other associated factors (Raoand Nagamani 2010, Rao et al. 2015). Thus any effortinvolving improvement in food grain production to meetcurrent and future food demands and double the farmers?income must involve rice and weed management. Theobjective of the present analysis is to assess weedmanagement role in attaining higher crop production and to double the income of rice farmers in India
