- The calculation of H2 of a variety was based on the variety’s four plot CHs, including two N treatments and two replicates. Because only CHs under 0.82 m of FM were used for comparison, the H2 value of varieties can be calculated only when all four plots’ CH of a variety were below 0.82 m. - represents no varieties within the group that meet the above conditions. The underlined values represent the best results among different height measurement methods (each row) with regard to different subgroups of CH, LAI, and GS. The bold values were the mean vaules of different 3D sensing datasets (each column) across all subgroups of CH, LAI, and GSÂ
