The manufacturing production index (MPI) declined for the 11th straight month in March, down 11.25% from a year earlier, hurt by lower production of cars, sugar and petroleum, the industry ministry said on Wednesday.
The performance compared with a forecast drop of 6.25% in a Reuters poll, and against February's revised decline of 4.24%.
Capacity utilisation in March was 67.22%, after February's revised 66.06%.
