SINGAPORE (Reuters) - Singapore's non-oil domestic exports probably fell for a second straight month in March, a Reuters poll of economists found, an indication that slower global growth keeps denting the city-state's trade.

Non-oil domestic exports (NODX) were expected to have slid 0.7 per cent from a year earlier, according to the median forecast in the survey of 10 economists.

In February, non-oil domestic exports fell 9.7 per cent from a year earlier, as shipments to China contracted and the Lunar New Year holiday impacted business.

On a seasonally adjusted basis, non-oil domestic exports in March were seen rising 3.5 per cent from the previous month, when they dropped 9.4 per cent from January.

The trade data will be released on Friday at 8:30 a.m. (0030 GMT).

Singapore's manufacturing activity hit a three-month low in March, contracting for a fourth consecutive month, as new orders declined, a survey showed.
