OKLAHOMA CITY (AP) — State Treasurer Ken Miller says Oklahoma's two-year revenue growth streak has come to an end.

Miller said Tuesday that state revenue collections in March fell slightly below collections from the same month last year. Total collections for the month totaled about $921 million, down less than $3 million from collections in March 2011.

Miller says the biggest drop among the state's major sources of revenue was the gross production tax on oil and natural gas. He says revenue from that tax was down 36 percent in March.
