Cotton varieties all respond differently to plant growth regulator (PGR) treatments. It is important to understand the response of new cotton varieties to PGR application rates.
The objective of this experiment was to evaluate the response of four Deltapine® cotton varieties to PGR application over two years for plant height and yield response.
