MOSCOW, April 14 (Reuters) - Kazakhstan, which persistently exceeded its OPEC+ oil output quota, increased its crude oil production further in March by 37,000 barrels per day, breaching the restrictions again, OPEC data showed on Monday.

The Central Asian country's oil production rose to 1.852 million bpd last month, above Kazakhstan's quota of 1.468 million bpd for January-March set by the Organization of the Petroleum Exporting Countries and allies including Russia - together known as OPEC+.

The energy ministry said last Thursday that Kazakhstan exceeded its OPEC+ quota in March but would fulfil its commitments in April and partially compensate for earlier overproduction, according to Interfax news agency.

An industry source told Reuters on Monday that Kazakhstan's oil output fell in the first two weeks of April from the March average, but is still above the OPEC+ quota.

Russia's crude oil output edged down 10,000 bpd last month to 8.963 million bpd, compared to the country's quota of 8.978 million bpd for the first quarter, according to OPEC.
