The growth of eight infrastructure sectors slowed down to 4.2 per cent in August against 4.4 per cent in the year-ago month on account of decline in production of crude oil and fertiliser.
The output of crude oil and fertiliser dipped by 3.7 per cent and 5.3 per cent respectively, according to the data released by the commerce and industry ministry on Monday.
On the other hand, coal, natural gas, and electricity production grew by 2.4 per cent, 1.1 per cent and 5.4 per cent respectively compared to 15.4 per cent, 4.2 per cent, and 8.3 per cent respectively in August 2017.
Refinery products, steel and cement also recorded positive growth.
During the April-August period of the current fiscal, these sectors have grown 5.5 per cent as against 3 per cent in the year-ago period.
