How to Interpret Cotton Seed Cool and Warm Germination Tests for Planting Decisions
Sudeep S. Sidhu
This publication discusses warm and cool germination tests for cotton seed quality and ways to interpret these results. A warm germination test is a good predictor of seed germination when cotton is grown under favorable conditions. Cool germination test results only provide an indication of the performance of a given seed lot when planted under unfavorable conditions. This publication is intended for growers, crop advisors, and Extension agents. Written by Sudeep S. Sidhu, and published by the UF/IFAS Department of Agronomy, April 2026.
