摘要

India is world's largest producer of sugar and sugarcane. Sugarcane is cultivated in about 4.09 million ha producing about 283 million t of cane with an averge productivity 72.6 MT/ha. Of the several agricultural crops, sugarcane is the most remunerative crop and has a very high economic piomass to total biomass ratio. Its requirements for water and fertilizer are equally very high. About 60% of cane in India is in the subtropical zone and 40% in tropical zone. The productivity varies significantly between these zones; is 89 & 58 MT/ha, respectively. In India area under Sugarcane is highest, 21.4 lakh ha. in UP. The productivity of MP is lowest, 39.3 MT/ha and that of Tamilnadu is highest, 134.2 MT/ ha in the country. Except in Maharashtra, Sugarcane is grown with flood irrigation in all other states. productivity of cane is declining due to excess use of water & imbalanced fertiliser doses. The average yields of sugarcane in the major states are shown below.
