Digital photography is becoming a powerful tool that enables a real-time management of large agricultural areas with a few resource requirements. Its subsequent processing and interpretation determines a lot of information over large agricultural and forestry areas. The application of this tool in Agriculture at the farm level allows to calculate the vegetation cover fraction. This parameter is defined as the proportion of land intersected by the vertical projection of vegetation. Vegetation cover fraction has a major importance in vegetation monitoring. Moreover, it is strongly correlated with the growth of a crop. Additionally, it is widely used to determine crops water requirements using FAO-56 methodology. The evolution of cover fraction indicates the phases of crop growth. The aim of this study is to determine the relationship between the ratio cover fraction versus plant height and crop coefficient. For this purpose a new methodology based on processing the digital image of a plant cover was tested. The variety of lettuce Little Gem was employed in this experiment. This paper shows the applicability of this digital photography methodology for determining crop water requirements.
