Long term research at the University of Arizona have found that the Upland and Pima cotton varieties grown in Arizona can be tracked over their growth cycle by the use of several simple measures. Plant mapping is a method of measuring cotton growth and reproductive development. Measurements of height to node ratio, fruit retention and nodes above white flower can be correlated to crop management, and yield estimation. As a reminder, members of the UA Extension Ag Team have produced set of short videos demonstrates basic cotton plant structure and plant mapping procedures.

The hot and dry forecast will ensure high rates of water use in the coming weeks. Water stress at this time of year can reduce plant stature and lead to square abortion. Monitor soil moisture closely and avoid water stress through timely irrigations.
