According to Election Commission (EC) officials, 43 per cent voters had exercised their franchise in Gorakhpur when official voting hours ended at 5 p.m. while this percentage was just 38 per cent for the Phulpur seat in Allahabad.
Voters still in the queues outside various polling stations at the end of the voting hours will be allowed to vote, a poll official said, pointing out that it will lead to a marginal increase in the voting percentage.
Snags in the electronic voting machines (EVMs) were reported from some places. Polling was held up at Kidwai College in Allahabad (East) for some time due to a technical glitch.
In Gorakhpur, the lowest voter turnout of 33 per cent was in Gorakhpur city, and the highest 47 per cent in Sahjanwa and Campierganj.
Both Chief Minister Adityanath and Maurya claimed victory for the BJP candidates, irrespective of the voter turnout in the two seats.
After casting his vote, a beaming Adityanath told reporters that the "BJP continues to get a groundswell of public support since they are witnessing development, peace and prosperity under its government".
He also denied the influence of the Samajwadi Party-Bahujan Samaj Party alliance on the bypoll results.
"This is an unholy and opportunistic alliance and the people know their real agenda very well and will thus defeat them emphatically," the Chief Minister said.
Maurya, after casting his vote along with his wife and son, said the victory margins will be big in both seats in favour of the Bharatiya Janata Party.
"On March 14, when the votes are counted, the Bua-Bhatija (Mayawati-Akhilsh Yadav) will suffer another sad jolt."
Bharatiya Janata Party's Upendra Dutt Shukla is in the fray in Gorakhpur, represented by Adityanath since 1998. Gorakhpur has 970 polling centres and 2,141 polling stations.
There are 19.49 lakh eligible voters, including over 8 lakh women.
The Congress is fighting on its own and has named Surahita Kareem as its candidate.
The Phulpur seat has 793 polling centres and 2,059 polling stations. A total of 19.63 lakh voters decided the fate of 22 candidates.
