The National Cereals and Produce Board (NCPB) is set to start buying maize on Wednesday at 2,500 shillings per 90 kilograms bag.
The announcement comes few days after President Uhuru Kenyatta ordered the price increase from Kshs 2,300 to Kshs 2,500 that the Cabinet had approved.
NCPB officials said on Monday the stores would open from Wednesday after the Strategic Food Reserve Trust Fund gave the green light to buy the maize.
Farmers in the North Rift have been queuing at NCPB depots to deliver their maize.
They had on Monday issued a two-day ultimatum to the government to start buying maize or face demonstrations.
Many farmers said they were unhappy with the government’s offer but would only sell their maize to NCPB to avoid exploitation by brokers.
The government maintains that the new price was determined by market forces. National Food Strategic Reserve Board chairman Noah Wekesa said the Treasury had already released funds to buy maize.
