Notwithstanding any other provision of law, in the determination of farm yields the Secretary may use projected yields in lieu of normal yields. In the determination of such yields the Secretary shall take into account the actual yield proved by the producer for the base period used in determining the projected yield, and the projected yield shall not be less than such actual yield proved by the producer.
