Answer Details
Yellow coloration of the lower leaves of a growing maize plant may be due to a deficiency in nitrogen. Nitrogen is an essential nutrient required by maize plants to grow and develop properly. When there is a lack of nitrogen in the soil, the plant will not be able to produce enough chlorophyll, which is responsible for the green color in plants. This will cause the lower leaves to turn yellow due to chlorosis. Therefore, a deficiency in nitrogen can lead to yellowing of the leaves in maize plants.
