The party announced names of candidates for two of the state's 21 Lok Sabha seats and 16 of the 147 assembly segments, a party press release said.
The candidates were selected at a meeting presided over by OJM president Pyarimohan Mohapatra.
The meeting also discussed the issue on possible alliance with BJP.
As the proposed alliance was being opposed by some state leaders, some members suspected a nexus between BJD and some BJP leaders, the release added.
