The symptoms of Zn deficiency do not appear in the early stages except for stunted growth. The first be applied before sowing. symptoms appear on the base of the third leaf as pail yellow stripping to a board band of white or yellow tissue-.-with radish purple veins between the midrib. In severe cases of deficiency in Maize unfolding young leaf may be white or yellow, hence the name "White bud in Maize/ Corn".

Foliar Application: For spraying one hectare crop, dissolve 2.5 Kg. Zn Sulphate and 10 Kg Urea (or 1.25 Kg slaked lime) in 500 litters of water at-least 2 to 3 times at an interval of 7 to 10 days.

The first effect of Zn deficiency appears at the tillering initiation stage in the form of fading of tissue between midrib and edges of leaf (third leaf from the top) in middle or lower half of lamina. This is followed by loss of green colour between the veins and light to dark ) brown spots (necrotic lesions) in middle of the leaf blade. The necrotic areas intensify and coalesce resulting in collapse of affected leaves from the middle. Plant growth is restricted. Earring and maturity are delayed.
