Estimating the leaf area of plant species entails many benefits, such as prediction of the productive potential and the achievement of optimal management practices in irrigation, fertilization and soil use. The purpose of this study was to compare the accuracy of four methods that are commonly employed to estimate leaf area in forage species. Three of these methods are categorized as destructiv...

Regression models to predict leaf area and weight in common bean (Phaseolus vulgaris) were fitted using the three leaflets of leaves. A total 1504 leaves from 40 genotypes collected, covering a large range sizes. Width, length, area, measured for each leaflet. The was obtained by sum left, central, right leaflets. dataset randomly divided into training validation sets. set used model fitting se...

Spectral vegetation indices are frequently used to estimate vegetation biophysical/biochemical characteristics. In general they have been proposed to reduce spectral effects caused by external factors such as the atmosphere and the soil background. This study evaluated narrow band vegetation indices for estimation of vegetation leaf area index. The study takes advantage of using a dataset colle...
