Research Project: COTTON HARVESTING RESEARCH APPLICATIONS TO ENHANCE PRODUCTION MANAGEMENT
2010 Annual Report


1a.Objectives (from AD-416)
Use data gathered during harvest to develop and improve crop management tools.


1b.Approach (from AD-416)
Test plots located on the Texas High Plains will be planted with multiple cotton varieties and grown under irrigated and non-irrigated conditions. Remote sensing of the plots at various stages of growth will be performed to evaluate the status of the plants. The plots will be harvested with a machine equipped with a yield monitor. The yield data will be correlated with the remote sensing data to develop yield prediction algorithms.


3.Progress Report

Field-scale plots were planted with multiple varieties and harvested using a spindle type cotton picker with yield monitor to evaluate the yield stability of different varieties. Environmental stress was applied to the crop in each plot in terms of water availability (via varying soil structure), nutrient availability (competition with volunteer cotton plants), and insect pressure. Remotely sensed reflectance data was collected three times during the year to use in evaluating the in-season crop response to environmental stress. Analysis of varietal performance based on lint yield and biomass production responses is underway. Additional studies are planned for the 2010 harvest season. The ADODR monitored activities via email and phone calls at least once every quarter and weekly during the months of October through December.
