Many hybrid maize-growing areas may be deficient in zinc. Soil application of 25 to 50 kg of zinc sulfate is recommended once in every 3 years. If soil application is not done and zinc deficiency is observed on plants, 0.2% zinc sulfate solution is to be sprayed 2 or 3 times at weekly intervals till the symptoms do not reappear.
