A natural occurring class of plant hormones cytokinins has been found to help increase cotton yields during drought conditions. It has been observed that young cotton seedlings have small root system, making it difficult for them to reach available soil water. Cytokinins assists the young plants in water stress defences, promoting the plant to quickly build a bigger root system to access deep soil mosture. To be effective this phytohormone should be at an early stage of development.
