ALGIERS, April 25 (Reuters) - Algeria's economy grew by 3.9 percent in 2015, up from 3.8 percent the previous year, boosted by higher output in agricultural sector, the government said.

Last year's growth was slightly higher than the 3.8 percent government forecast and the 3.7 percent International Monetary Fund (IMF) expectations.

Algeria relies heavily on oil and gas, which make up 60 percent of the state budget and 95 percent of total exports.

After the fall in crude oil prices, which has significantly hit its finances, Algeria has been trying to diversify the economy through incentives to develop the non-petroleum sector but those efforts are still in their infancy.

Hydrocarbon sector grew 0.4 percent last year after a 0.6 percent decline in 2014, according to the National Statistics Office data released on Sunday. Growth in the non-oil sector stood at 5.5 percent in 2015 slightly lower than the 5.6 percent the previous year.

But agriculture output grew 7.6 percent, up from 2.5 percent in 2014, the figures showed. Algeria's grain output in 2015 reached 4 million tonnes, a 14.3 rise from 20114.
