The increase in price has created war between millers and the National Cereals and Produce Board in Kenya, which is hindering attempts by the State to build up food reserves.
According to NCPB on Thursday, it had managed to purchase 987,844 bags of maize against a target of six million bags that the Agriculture ministry had projected this year.
The National Strategic Food Reserve currently has 1.3 million bags of maize, 400,000 from the previous season, against the required three million bags.
The reserve should at any given time have the three million bags that can sustain the country for a month in case of an emergency.
Treasury secretary, Henry Rotich says Board has enough capital that can replenish the National Strategic Food Reserve to the previous levels.
