India sugar production in 2017-18 (Oct-Sep) is set to fall short of even the most conservative of government estimates, of 23.5 million tonne, Kolhapur-based Warana Sugar Ltd told in the Sugar Conclave-2017 being held in the city. Warana estimate for sugar output is more than 6% below the lower end of the food ministry projection of 23.5-24.0 million tonne and 12% lower than the Indian Sugar Mills Association estimate of 25.1 million tonne.
