    Solution

    White bud of maize is due to Zn deficiency in which a white or light yellow band with reddish veins appears on each side of mid-rib, beginning at the base of the 2nd or 3rd leaf from the top of the plant two weeks after seedling emergence. Later white band extends in strips while mid-rib and leaf remain green.
