This study revealed that an area meter with a semi-automatic feeding mechanism underestimated the area of yellowish leaves and wavy leaves in crop plants. It is recommended that area measurements should be made using photocopied leaves and leaf segments. The degree of underestimation should be checked when chlorophyll meter (SPAD) values are less than 30.
