The determination of leaf area is of interest to producers and sectors of research, and techniques should be simple, quick and accurate. This study aimed to compare methods for estimating leaf area of Barbados cherry in orchard. 60 leaves were collected randomly, and after collection, were measurements of leaf area by five methods: squares, linear dimensions, leaf area integrator AM 300, leaf disks and Digital Image Analysis (Scanner). All methods were compared with the reference method (scanner), based on the criterion of determination coefficient of linear regression (R2). The method that is closer to the leaf area of reference was the integrator portable AM 300.
