The deficiency of nitrogen in a maize plant can be corrected by applying?

The correct option to correct nitrogen deficiency in maize plants is sulphate of ammonia. Nitrogen is an essential nutrient for plant growth and plays a key role in the formation of chlorophyll and the production of proteins. When a maize plant lacks nitrogen, its leaves may turn yellow and stunted growth may occur. Sulphate of ammonia is a fertilizer that contains nitrogen in the form of ammonium sulphate. When applied to the soil, the ammonium sulphate breaks down and releases nitrogen, which is taken up by the roots of the maize plant. This helps to correct the nitrogen deficiency and improve the overall health and growth of the plant.
