Water Deficit and Irrigation Response in Upland Cotton

Description:

Intro: Although cotton is able to thrive in many different moisture regimes and soil types, water availability proves to be the most limiting factor to successful cotton production.  Main-stem node counts and amounts of canopy light interception show pertinent information about such parameters as growth rate, water use, maturity, and earliness.

Objectives: Evaluate plant response to four different irrigation regimes by using main-stem node counts, starting at bloom, and quantifying canopy light interception.  Then make comparisons across two different depths to sand (varying soil types).
