Nutrient Management Programs for Cotton Growers in the Texas Coastal Plain: Petiole Testing

Daniel J. Lawlor


Growers benefit from the information obtained from petiole tests. A sound basic soil fertility program combined with petiole analyses should provide a means to limit excess fertilizer inputs while obtaining maximum economic yield. Field demonstrations were set up to determine how well current petiole recommendations apply to growers in the Texas Coastal Plain. Lint yield was increased by foliar N in two of the five field demonstrations, indicating that further tests are needed to determine any adjustments in recommendations that may be needed.
