After last fiscal's double-digit expansion, industrial production picked up more steam to grow by 17.6 per cent in April, boosting the prospects of achieving 8.5 per cent economic growth in 2010-11. The increase in output was due to a robust showing by the manufacturing sector and a low-base effect, caused by the global economic slowdown. Manufacturing—which accounts for around 80 per cent of the Index of Industrial Production or IIP—expanded by 19.4 per cent in April, with capital goods growing by 72.8 per cent and consumer durables by 37 per cent. The April figure is almost equal to the 20-year-high output of 17.7 per cent achieved in December 2009.However, Finance Minister Pranab Mukherjee said his appetite is infinite and he had expected the industry to do even better in April. While the double-digit growth has strengthened the case for stimulus rollback, Planning Commission Deputy Chairman Montek Singh Ahluwalia cautioned that withdrawal should not be quickened.Encouraged by Friday's figures, Prime Minister's economic advisor C Rangarajan said the Indian economy is well-poised to achieve the projected growth rate of 8.5 per cent in the current fiscal.
