### NDVI--Local Variety  
The Treemap graph in Figure 4 shows the mean value of the Normalized Difference Vegetation Index (NDVI) for all treatments at all three salinity levels of the local variety. In general, it appeared that from time 36 DAS onwards, NDVI, in almost all treatments, no-priming (T1), hydropriming (T2), biopriming (T3), hydropriming/biopriming (T4), showed a decrease as plant growth progressed, except for treatment T2 \(|\) 80. This result prompted the completion of the salinity application experiment, and the time point of 52 DAS was the starting point for agronomic trait measurements.  
In Figure 5, the four treatments were compared with each other within each DAS separately for each salinity level to assess their effect on the NDVI. The results showed that hydropriming (T2), biopriming (T3), and hydropriming/biopriming (T4) treatments gave higher NDVI index values compared to the no-priming treatment (T1). The hydropriming/biopriming (T4) treatment at time points 36 DAS and 52 DAS showed statistically significant differences compared to the no-priming (T1) treatment at salinity levels of 80 NaCl and 160 NaCl.  
Figure 2: Treemap plot for the average NDVI values in the commercial variety, at three different time points (25 DAS/36 DAS/52 DAS). The mean values of the NDVI for each DAS per treatment are shown as rectangular squares. The rectangular squares are arranged by column (treatment) in descending order. The highest average NDVI values are placed at the top of the column. Different Latin letters indicate significant differences according to the test of Least Significant Difference (LSD) at \(p<0.05\) between the three different DAS per treatment. T1 0: no-priming/salinity level 0, T2 10: hydropriming/salinity level 0, T3 10: biopriming/salinity level 0, T4 0: hydropriming–biopriming/salinity level 0, T1 180 mM NaCl: no-priming/salinity level 80 mM NaCl, T2 180 mM: hydropriming/salinity level 80 mM, T3 180: biopriming/salinity level 80 mM, T4 180 mM: hydropriming–biopriming/salinity level 80 mM, T1 160 mM: no-priming/salinity level 160 mM, T2 1160 mM: hydropriming/salinity level 160 mM, T3 160 mM: biopriming/salinity level 160 mM, T4 160 mM: hydropriming–biopriming/salinity level 160 mM. 25 DAS: 25 days after sowing, 35 DAS: 35 days after sowing, 52 DAS: 52 days after sowing, 52 DAS: 52 days after sowing.  
Figure 4: Treemap plot for the mean NDVI values in the local variety at three different times (25 DAS/36 DAS/52 DAS). The mean values of the NDVI variable for each DAS per treatment are shown as rectangular squares. The rectangular squares are arranged by column (treatment) in descending order. The highest average NDVI values are placed at the top of the column. Different Latin letters indicate significant differences according to the Least Significant Difference (LSD) test at \(p<0.05\), between the three DAS per treatment.

Different Latin letters indicate significant differences according to the Least Significant Difference (LSD) test at \(p<0.05\).
