Results and Disscussions
1.2.1. LAI Field Observations
The LAI values were collected from the field using the plant canopy analyzer. Sixteen gardens were selected out of which four gardens each were declared as high yielding, medium yielding and low yielding gardens respectively. The LAI reading for each division of the gardens were recorded on the basis of healthy, moderately healthy and affected tea patches. Three LAI observations were taken along with the GPS points and from each observation two readings were recorded. The average of the two readings gave the actual LAI value for the single point. These LAI values were used for observing the LAI variability with the MODIS LAI and NDVI.
