The latest attack happened in the village of Malam Karanti on Thursday morning, the security sources and residents said.
A spokesman for Nigeria’s army did not respond to phone calls and text messages seeking comment.
Local resident Sani Auwal said by phone that militants had gathered farmers and fishermen near the village and killed 23 people, many of them bean farmers.
They spared an elderly man who later alerted the community, he said.
Last month Borno’s governor acknowledged that Boko Haram had renewed attacks and kidnappings in the state, reversing previous gains by security forces.
