Which of the following represents a negative impact on fiber uniformity?

In the context of cotton production, fiber uniformity refers to the consistency in the length, diameter, and strength of the cotton fibers harvested. Inconsistent rainfall can lead to a wide range of stress factors affecting the cotton plants throughout their growth cycle. When rainfall is irregular, it can cause periods of drought followed by excessive moisture, leading to variations in plant growth and development. This inconsistency directly impacts fiber characteristics, as stress can result in shorter, weaker, or otherwise variable fibers that affect the quality and uniformity of the cotton produced. So, when considering factors that influence fiber uniformity negatively, inconsistent rainfall is a significant concern.
