Comparison of Various Kinds of Vegetative Indices for Chlorophyll Contents Using Low-Resolution Camera

Nitrogen management is crucial for high yield potential of crops as well as reducing environmental pollution. However, the heterogeneity of nitrogen condition. Thus, there have been attempts to estimate nitrogen contents via chlorophyll contents in leaves. Among them, vegetative indices have been proved to be useful. However, there are many kinds of them and each of them reflects different properties. Here, we compared with various indices using one data set to show they are different each other so that researchers who want to use vegetative indices can be aware of this. By doing so, they can develop their own models with the proper indices.
