Estimating an average voter turnout of 63.69 per cent, the poll officials said the percentage is likely to increase a little as it was still an hour left for the voting.
Polling was brisk during morning hours, but it slowed down in afternoon, picking up again towards the evening with enthusiastic voters, mostly first-timers, lining up in long queues outside several polling centres.
Poll officials said till 6 pm Saharanpur recorded maximum voter turnout at 70.68 per cent, while the least turnout was reported for Ghaziabad Lok Sabha seat where it stood at 57.60 per cent.
The voting percentage in Kairana was 62.10 percent, Muzaffarnagar 65.66 percent, Bijnor 65.40 per cent and 60.15 per cent in Gautam Buddha Nagar, they said.
At a Kairana polling booth, a BSF jawan fired in air to disperse some people, who were not carrying their identity cards and tried to forcibly enter the premises to cast vote, police said.
The incident took place at a polling booth in Rasoolpur Gujran village under Kandhla police station around noon.
In Muzaffarnagar, BJP MP Sanjeev Balyan stoked a controversy by demanding that male officials check the identity of burqa-clad women at poll stations where women security personnel had not been posted.
"If someone comes in a burqa, whether the same person is coming four or five times, how will you check," Balyan told reporters in Muzaffarnagar.
Some security personnel on election duty in Noida were served meals in packets labelled "Namo Foods", triggering criticism from the opposition even after the local police said the packs only displayed the name of the food shop.
The packets were brought in the boot of a hatchback and distributed among police personnel in Noida's sector 15A around 9.30 am, while polling was on in the Gautam Buddh Nagar constituency under which the Delhi suburb falls. Union minister Mahesh Sharma is the Bharatiya Janata Party candidate seeking re-election there.
The packets, coloured in a shade of saffron, had 'Namo Foods' emblazoned on top in Hindi. They soon started generating a buzz among curious onlookers.
