What is the optimal temperature range for cotton growth?

The optimal temperature range for cotton growth is primarily between 70°F to 95°F (21°C to 35°C). This range is critical because cotton is a warm-season crop that thrives in warmer temperatures. Within this temperature window, cotton plants typically exhibit optimal photosynthesis, growth, and development.

Temperatures below this range can slow growth and lead to poor fiber development, while temperatures above this range can cause heat stress, negatively affecting yield and quality. Therefore, maintaining temperatures consistent with this range is crucial for maximizing cotton production.

Other ranges presented may not provide the necessary warmth for optimal growth. For instance, the lower temperature ranges would not support vigorous growth and could delay the developmental stages of the cotton plant.
