At what stage should a cotton grower prioritize nitrogen applications for optimal growth?

Prioritizing nitrogen applications before the first square is crucial for optimal cotton growth because this timing aligns with the plant's need for nitrogen during its early development stages. Nitrogen plays a significant role in promoting vegetative growth and setting the foundation for the plant's future productivity.

At this early stage, the cotton plant is focusing on establishing a robust root system and leaf area, which are essential for photosynthesis and overall plant health. Adequate nitrogen availability encourages vigorous growth, leading to enhanced square formation and, subsequently, fruit set.

Applying nitrogen too late, such as during flowering or after the first flower, may not provide the plant with the necessary nutrients when it needs them most. Likewise, waiting until the end of the season misses the opportunity to optimize early development, which is critical for ensuring a higher yield potential.
