“…The P2 treatment has a low seedling robustness value and the P0 treatment has a high seedling robustness value. Plants will have a high chance of survival if they have a low robustness value (Sanusi et al, 2022) and vice versa, plants will have a low chance of survival if they have a high robustness value (Irmayanti et al, 2019). The results of the analysis carried out as a whole in each treatment show that the robustness value is still categorized as good and optimal.…”
