Defining critical leaf‐ and petiole‐potassium concentrations for monitoring cotton nutritional status

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Plant tissue testing is an effective tool for diagnosing crop nutritional status; however, critical tissue‐potassium (K) concentrations have not been established for modern cotton (Gossypium hirsutum L.) cultivars. We aimed to define critical leaf‐ and petiole‐K concentrations at various growth stages for optimal cotton production.
