A state election office spokesperson said the average poll percentage was 34.92 per cent.
While Sultanpur parliamentary constituency recorded the highest turnout of 38.87 per cent, enthusiasm among voters was the least in Phulpur, where 29.20 per cent cast their ballots.
Altogether, 177 candidates are contesting in these 14 constituencies, where 2.53 crore people are eligible to vote at 16,998 polling centres.
In Sultanpur, Union minister Maneka Gandhi and her rival BSP candidate Chandra Bhadra Singh alias Sonu had a face-off. Gandhi warned him that hooliganism wouldn't work, but Singh dismissed her charge.
He also said there have been complaints about EVMs and VVPAT machines, and the machines have been replaced.
Polling was underway in Sultanpur, Pratapgarh, Phulpur, Allahabad, Ambedkararnagar, Shrawasti, Domariyaganj, Basti, Sant Kabirnagar, Lalganj, Jaunpur, Machchlishahr, Bhadohi and Azamgarh constituencies in Purvanchal region of the state.
However, the BJP had to bite the dust in the bypolls in Phulpur and Gorakhpur constituencies last year.
While the anti-BJP alliance would like to retain its grip over both the seats, the saffron party is looking to take a sweet revenge from the opposition in this round.
The SP president's decision to contest from his father's bastion is being touted as a move to consolidate the Yadav, Dalit and Muslim voters in the Purvanchal region of Uttar Pradesh.
The seat appears tricky for Maneka Gandhi as BJP strategists are relying on a division of Congress and gathbandhan votes, besides possible counter-polarisation of non-Yadav and non-Jatav Dalit and OBC votes.
