The Bhumihars have significant presence in 12-15 out of the 54 seats of nine districts going to polls on Monday.
Details about how many seats each party will contest will be announced later, their leaders said.
Nishad said he will meet senior BJP leaders, including Amit Shah, in Delhi on Monday to finalise the constituencies where the party will field its candidates.
As per the sources, Anupriya Patel has demanded over a dozen seats this time -- half of them from eastern UP and the rest in the Bundelkhand region.
In a statement Sunday in Prayagraj, he said Shringi Rishi Nishad and not king Dashrath was the father of Lord Ram, prompting the opposition to demand a reaction from the ruling BJP.
Meanwhile, two former senior leaders of BSP -- Lalji Verma and Ram Achal Rajbhar -- met Samajwadi Party chief Akhilesh Yadav.
The survey report would be submitted to BJP national president JP Nadda to finalise the seat-sharing formula for the election, Nishad party sources said.
