  1. The values in the table are Coefficient of determination (R2) of LAI and LG with peanut pod yield. The LAI and LG are manually measured and aerially derived using regression and aerial neural network (ANN) models in 2017. The values followed by an asterisk (*) has a significant model at α = 0.05.
