Labourers are seen working on road construction in Siliguri on May 10, 2012. Seeking to spur growth further, India' central bank in April lowered interest rates for the first time in three years, with a bigger-than-forecast 50 basis points cut in interest rates.
Growth in manufacturing, mining and electricity output from a year earlier sharply undershot consensus expectations of a 1.5-percent rise.
The data marked a significant turnaround from February's 4.1-percent output increase and the 9.4-percent rise logged in the same month a year earlier.
The contraction was another sign of the slowdown gripping India's economy, fed by weakening global and domestic demand.
The key manufacturing sector shrank by 4.4 percent in March in contrast to an 11-percent rise in the same month a year earlier.
