Detection of Water Stress in Cotton Using Multispectral Remote Sensing

S.J. Maas, G.J. Fitzgerald, W.R. DeTar and P.J. Pinter, Jr.


 
ABSTRACT

A study was conducted 1n 1998 to investigate the feasibility of using remote sensing to monitor the onset and progression of water stress in cotton (Gossypium hirsutum L.). The study involved thermal infrared observations on a set of field plots subjected to intermittant water stress. Both ground- and aircraft-based observations showed a pattern of increasing canopy temperatures for plots deprived of irrigation, followed by recovery of the plant canopy after irrigation was restored. Differences between temperature conditions observed on the ground and in remote sensing imagery were attributed to canopy ground cover effects.
