Making a statement in the Assembly, Rohluna said there were issues to be solved before actual implementation and Chief Minister Lal Thanhawla had taken it up with the Centre.
Of the total population of around ten lakh, 6.33 lakh people (38.74 per cent in urban and 78.47 per cent in rural areas) would be covered by the National Food Security scheme in accordance with tentative figures released by the National Sample Survey, he said.
The additional requirement would cost the state exchequer an additional amount of Rs two crore per month, Rohluna said.
If the Centre discontinued the current allocation of rice under Public Distribution Scheme (PDS), the state government would have to bear an additional Rs 7. 82 crore per month, he said.
Earlier, the Chief Minister told reporters on his return to Aizawl after attending the meeting of Congress chief ministers in New Delhi, the state would not be able to implement the Food Security scheme.
