Input costs rose for the 19th straight month for manufacturers, amid indications that persisting inflationary pressure may force the Reserve Bank to continue with its 'neutral' monetary policy stance, to which the central bank recently shifted from an earlier 'accommodative' mode.
The Nikkei Markit India Manufacturing Purchasing Managers' Index (PMI) -- an indicator of manufacturing activity -- matched March's reading of 52.5 in April as well.
Though the upturn in order books was "most pronounced" since last October and new export orders rose for the third month in a row, the rate of factory output growth eased from March.
April is the fourth straight month in which manufacturing sector registered a growth after the demonetisation-induced contraction at the end of 2016.

"Buoyant domestic demand coupled with sustained growth of new orders from abroad boosted the upturn in total new business received by Indian manufacturers in April," said Pollyanna De Lima, Economist at IHS Markit and author of the report.
The Reserve Bank in its monetary policy review meet on April 6 kept the repurchase or repo rate -- at which it lends to banks -- unchanged at 6.25 per cent but increased reverse repo rate to 6 per cent from 5.75 per cent.
"Scratching beneath the surface we can see that consumers were the key drivers of growth as consumer goods producers registered by far the steepest expansions in both production and new orders," Lima said.
