What is a common consequence of nitrogen deficiency in corn?

The common consequence of nitrogen deficiency in corn is indeed the noticeable symptom of pale leaves and stunted growth. Nitrogen is a vital nutrient for plants, playing a crucial role in the synthesis of key components like proteins and chlorophyll. Chlorophyll is essential for photosynthesis, the process by which plants convert sunlight into energy. When corn plants lack sufficient nitrogen, their ability to produce chlorophyll is compromised, leading to yellowing or pale leaves, which is often referred to as chlorosis. Furthermore, without adequate nitrogen, the plants struggle to grow properly, resulting in stunted growth as they cannot develop healthy tissues and structures.

In contrast, increased weed competition is not a direct result of nitrogen deficiency in corn but rather can occur due to a variety of factors, including soil conditions and weed management practices. Enhanced flowering and improved drought tolerance are also not associated with nitrogen deficiency; instead, adequate nitrogen typically encourages healthy growth and flowering.
