Figure 6. Data represent analysis of variance results between treatments for benchmark indices (BI) calculated during PE 3. Benchmark indices are listed along the y axis, and treatment along the x axis for a single data acquisition with a corresponding soil water content of 3.02% 
v. Benchmark indices were calculated as follows: NDVIBI = NDVIpredrought – NDVI, and GNDVIBI = GNDVIpredrought – G NDVI. Means followed by the same letter are not statistically significant (
= 0.05). To differentiate between ANOVA results for the GNDVIBI and NDVIBI, letters followed by an asterisk (*) denote ANOVA results for NDVIBI.
