For the full fiscal, the eight core sectors grew by 2.7 per cent in 2015-16, down from 4.5 per cent in 2014-15.
This was despite a sharp rise in the growth rate to 6.4 per cent in March for the eight sectors - coal, crude oil, natural gas, refinery products, fertilisers, steel, cement and electricity. These sectors, comprising nearly 38 per cent of India's total industrial production, had shrunk by 0.7 per cent in the year-ago month of March 2015.
Output in refinery products, fertilser, cement and electricity jumped by 10.8 per cent, 22.9 per cent, 11.9 per cent and 11.3 per cent respectively in March, according to the data released by the commerce and industry ministry.
However, crude oil and natural gas recorded negative growth during the month under review.
