Growing adapted varieties insures more stable production and creates newer wealth: Using unadapted varieties often invites disaster and causes wide fluctuation in feed and grain supplies. It is recognized that there are two important and profitable markets for grain in the state, namely, (1) market through livestock feeding and (2) industrial uses. Therefore, it will be of great advantage to the producer if he will carefully choose superior varieties that fit his area and his market.
