model to predict cotton growth stages

Asked June 21, 2016, 6:32 PM EDT

Is there a model (based on heat units or otherwise), predicting cotton growth stages, that you can recommend? We want to be able to apply the model worldwide (I guess that is pretty ambitious) - we are starting with the US. Thanks!

There is no model that exist that will work worldwide. Even in the US, there are differences from region to region. Model we use can be found here.

Temperate regions like Arizona use a different DD60 system due to higher diurnal fluctuations in temperatures in a desert environment

The one we and most of the other cotton growing sates use is in this book

Thank you very much.
