Estimation of leaf area in coffee leaves (Coffea arabica L.) of the Castillo® variety

Allometric models based on measurements of single leaf dimensions or a combination there are useful tools for determining individual leaf area (LA) because they are non-destructive, precise, simple and economical methods. The present study was carried out at the Central Station Naranjal of Cenicafé, located in the Department of Caldas (Colombia), four models were defined using the variables length (L) and/or width (W) to estimate LA in coffee leaves of the Castillo® variety (Coffea arabica L.). Estimation of regression coefficients was performed using information recorded from 6,441 leaves (...
