Manufacturing in India slowed in March but showed continued growth, a report from an economic research firm said. The HSBC Markit Economics manufacturing report said the headline index for India\'s goods-producing firms came in at 52 in March, down from 54.2 in February. Figures above 50 indicate business growth. Growth in new business orders accelerated in March, \"however, the PMI [purchasing managers\' index] was down to the lowest level in 16 months,\" Markit said.
