This paper describes a procedure for obtaining green plant cover from crop digital pictures. However, the appearance of shades caused by vegetation canopy characteristics, in addition to different coloration from several parts of the plant during the maturity process, makes evaluation difficult, especially when separating green vegetation from dry vegetation. In order to broach this problem, a methodology has been developed to obtain green plant cover. An experience in field radiometry is described where different average spectra have been captured for each experimental plot at the same time as pictures were taken, obtaining the Normalized Difference Vegetation Index (NDVI) for each one of the spectra. Finally we observe the relation between NDVI and green plant cover.
