"With UP having the biggest area under sugarcane production, it needs to share more responsibility in increasing India's overall sugar productivity," said the study titled 'Indian Sugar Industry: The way forward'.
"Tamil Nadu has the highest yield of over 100 metric tonne per hectare despite having third highest share of about 12 per cent in terms of sugarcane production and fourth highest share in terms of area under sugarcane production," it added.
It said that Maharashtra recorded highest share of about 33 per cent with about 80 lakh tonnes of sugar produced as of 2012-13 closely followed by UP which had about 31 per cent share with about 75 lakh tonnes of sugar production.
It said that UP also lags behind in terms of sugar recovery in the country as Maharashtra had the highest recovery of 11.25 per cent followed by Karnataka and Gujarat which had 10.4 per cent and 10.6 per cent respectively as of 2012-13.
However, a worrisome aspect emerges from the recovery statistics as it is seen that all the major sugar producing states have seen their recovery drop over the period 2001-02 to 2012-13, the study said.
