Goodluck Jonathan's order follows a car bomb explosion at a busy security checkpoint on the outskirts of Abuja on May 1, which left 19 people dead and 66 others wounded.
The explosion took place near the site of last month's bombing that left at least 75 people dead.
The development comes as Abuja plans to host the World Economic Forum on Africa from May 7 to 9.
Several regions of Nigeria have been hit by deadly violence in recent months.
In mid-April, armed men abducted hundreds of girls from a secondary school in the town of Chibok in Borno State.
Nigeria’s capital and its adjacent areas have been also rocked by deadly bombings several times over the past few years.
In May 2013, Jonathan declared a state of emergency in three northeastern states of Borno, Yobe, and Adamawa.
Boko Haram, which continues to fight against Nigerian President Goodluck Jonathan’s government, has conducted several deadly gun and bomb assaults in various parts of Nigeria since 2009.
According to recent figures gathered by the United Nations, more than 1,200 people have been killed in violence in the troubled regions since the state of emergency was imposed.
