Remote sensing technology is a valuable tool that is being
used to monitor and evaluate agricultural row crops. The objective of this study is to determine
if multi-spectral aerial imagery can be used to monitor soybean [Glycine max (L.) Merr.] growth
and development. Field experiments were
conducted at two locations in Central Indiana
in 2004 and 2005. Three different row spacing
were evaluated using multiple seeding rates and one soybean variety. Aerial CIR imagery was obtained at theV2
through R5 growth stage and used to create numerous vegetative indices for
analysis.
