Abstract : Reports on leaf area estimation in mango is rare and with little convergent results. The objective of this work was to determine the equations that best describe the relationship among the linear dimensions (length and maximum width) and the leaf area (LA) of mango cultivars Tommy Atkins and Haden, allowing the fast and non-destructive estimation of the leaf area just by using the length (L), the maximum width (W), or both. The leaf area of mango can be obtained by multiplying the product of the length for the width, and by the factor 0.74 (in cv. Tommy Atkins) or by 0.78 (in cv. Haden), as well as by using the equations: LA=4.96349 L-33.429 (R2=0.86); LA=17.2964 W-18.88065 (R2=0.85) and LA=0.73499 (L × W) + 0.59459 (R2=0.92) in cv. Tommy Atkins or LA=5.35282 L-33.17061 (R2=0.88); LA=19.09951 W-24.61777 (R2=0.89) and LA=0.76015 (L × W) + 0.43257 (R2=0.99) in cv. Haden.
