Basic Structure of a Cotton Plant

This video illustrates the basic parts of a cotton plant to help with understanding of cotton plant mapping.


Estimating the Vegetative/Reproductive Balance in Cotton: I. Height to Node Ratio

Research found that mainstem nodes are produced at a fairly regular rate, when the plant is not subjected to significant stress. Therefore, the number of mainstem nodes (above the colytedons) is a good measure of the crop age.


Estimating the Vegetative/Reproductive Balance in Cotton - II. Fruit Retention

Fruit retention is a quick and easy way to manage a well balanced cotton crop. It is often important to make an estimate of the fruit retention level of the crop when making decisions about basic crop management.


Estimating the Vegetative/Reproductive Balance in Cotton - III. Nodes Above White Flower

Nodes Above White Flower (NAWF) is an excellent tool to use as part of plant mapping. It gives us information on progression of the crop through the fruiting cycle.
