Mr Adityanath, who met constable Sagar's family in his native village Tikampaar to offer condolences, also promised employment to the children after completion of their studies, officials said.
The Chief Minister said a 'shaheed smarak' (martyr's memorial) and a girls' inter college will be set up in the village in the memory of the constable who was killed.
He also said that a road will be built to connect the village to the main road, the officials said.
To a demand for a gas agency for the family, he said a recommendation for the same will be sent to the central government.
Agriculture Minister Surya Pratap Shahi had earlier given a cheque for Rs 20 lakh to the family on behalf of the state government.
Constable Sagar and Army's Naib Subedar Paramjit Singh were killed and their bodies mutilated when Pakistani troops sneaked across the LoC upto 250 metres inside the Indian territory last week.
