Heidar Ali Nasr told the Iranian state TV that wheat purchases were continuing in 19 provinces in mostly warmer regions, Press TV wrote.
Earlier reports indicated that the southwestern province of Khuzestan had supplied nearly 1.7 million tons of wheat to GTC silos in the past two months.
Iran expects to buy some eight million tons of wheat from domestic farmers this year under its guaranteed purchase program.
Head of Iran’s Plan and Budget Organization (PBO), a body which is responsible for government resources and financing, said wheat is being purchased from domestic farmers at a guaranteed price of 150,000 rials ($0.3).
