According to Indian Sugar Mills Association (ISMA), "The gap in sugar production has narrowed down further from 13% to 11% over the last fortnight. 460 mills are still crushing sugarcane, which is 23 more than last year."
Sugar production in Maharashtra, the country's top producer, fell to 5.71 million tonnes till February of this year from 6.57 million tonnes in the year-ago period.
ISMA said mills in the state have recovered 11.1% of sugar, down from 11.15% of recovery in the year-ago period.
But the overall sugar recovery is expected to be 11.41% in 2013-14, better than last year, it added.
Sugar production in Uttar Pradesh -- the country's second biggest producer -- also declined to 4.27 million tonnes from 5 million tonnes in the review period.
However, recovery of sugar was slightly higher at 8.99% as against 8.94% in the same period last year.
Production in Tamil Nadu also declined to 5,70,000 tonnes from 9,92,000 tonnes due to lower recoveries and late starting of sugar crushing season.
Similarly, production in Gujarat was also down at 8,60,000 tonnes as against 8,89,000 tonnes in the year-ago period.
However, sugar output in Karnataka remained higher by 3% at 3.15 million tonnes so far this marketing year, ISMA added.
The country has exported 1.2 million tonnes of sugar so far, of which 5,00,000 tonnes was raw sugar. Above this, 1,00,000 tonnes of sugar has also been exported against the Advance Authorisation Scheme.
ISMA has pegged sugar production at 25 million tonnes for this year, which is higher than the government's estimate of 24.1 million tonnes and sufficient to meet domestic demand of 23.5 million tonnes.
