Normalized Difference Vegetation Index (NDVI)

There are two plots for NDVI. The first plot shows the NDVI values for the current season in comparison to the 5-year mean, values from the previous season, and the 10-year minimum and maximum values. As a crop season progresses, NDVI values will increase during early crop growth and development of leafy vegetation. NDVI will then reach the peak as the crop fully develops and reaches maturity, before senescence, and then decreases again as the crop matures and senesces as the leafy vegetation begins to die off. How the NDVI values progress over the course of the season and the individual peak values can help predict the productivity of the crops. The second NDVI plot shows the comparison of the current season NDVI values with the previous five seasons along with the resulting average crop yields from those seasons.
