Abstract

This atudy was conducted to determine if multispectral data from EATS-1 could be uaed to dstect differences in chlorophyll concentration between chlorotic (iron deficient) and green (normal) grain sorghum (Sorghum bicolor (L.) Moench) plants. Band 5 (0.6 to 0.7 m) data were relected, representing the chlorophyll absorption band at the 0.65-um wavelength. Chlorotic sorghum areas 2.8 acres (1.1 hectare) or larger were identified on a computer printout of band 5 data. This resolutton is sufficient for practical appllcations in detecting chlorotic areas in otherwise homogenous grain sorghum fields
