Progress Report Objectives (from AD-416) The objectives of this cooperative research project are to explore the application of remote sensing systems (visible, thermal, etc.) and develop novel analytical techniques for (1) determining crop growth stage, (2) detecting the onset of yield-limiting stress (e.g. water stress), and (3) determining potential insect infestation based on canopy development and crop physiological status. Approach (from AD-416) Hyperspectral and multispectral imagery in the visible, near-infrared and thermal bands will be collected using ground-based and aerial platforms from crop canopies displaying various characteristics as a result of changes in management. Novel analytical tools, such as Fourier transforms and principle component analysis, will be explored to analyze the data for maximal information retrieval. Synthetic spectra will be generated from individual components of the canopy reflectance and emission spectra for delineation of importance of each to the overall spectrum, and for comparison with aerial images. Remote imagery data will be corroborated with extensive biophysical, edaphic, physiological and entomological information of the crop canopy. Changes in leaf and canopy images will be correlated to specific physiological changes. Detection methodologies that reliably and accurately detect the onset of crop water stress can then be incorporated into decision support tools for irrigation management. Significant Activities that Support Special Target Populations This report serves to document research conducted under a Specific Cooperative Agreement between ARS and the Delta Research and Extension Service, Mississippi State University, Stoneville, MS. Additional details of research can be found in the report for the in-house project 6402-12130-001-OOD, "Development of Water Management Technology and Efficient Cropping Systems for the Mid South." The objectives of this cooperative research project are to explore the application of remote sensing systems (visible, thermal, etc.) and develop novel analytical techniques for 1) determining crop growth stage; 2) detecting the onset of yield-limiting stress (most particularly, water stress); and 3) determining potential insect infestation based on canopy development and crop physiological status. An improved camera system was installed on the moveable boom system for remote monitoring of canopy reflectance and visible and near-infrared imagery. A 3CCD-camera system, routed through a server, allows simultaneous capture of imagery in Red/Green/Blue, for later analysis. An improved system was installed for precision spray applications of insecticides. The system also allows measurement and visualization of crop yield. The close proximity of the Mississippi Agricultural and Forestry Experiment Station (MAFES) collaborator on the Stoneville campus encourages interaction between the collaborator and the ARS scientists. The ARS scientist regularly communicates with the MAFES collaborator via phone calls, e-mails, and direct office visits.

Progress Report 4d Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and the Delta Research and Extension Service, Mississippi State University.

A new near- to mid-infrared spectroradiometer was tested for its ability to monitor crop status. Limitations in the technology, requiring temperature stabilization near 25
C, greatly hampered its usefulness for monitoring in the extreme temperature conditions experienced within a crop canopy. Additional information on leaf and canopy biophysical parameters was collected to explore the interaction of canopy structure with microenvironment.
