“…The selection of these attributes is a very important task for predicting yield, as highlighted in previous works. [18][19][20] Thus, some variants were selected for the study, such as pruning times, data collection year (2017, 2018, and 2017 + 2018), all chemical attributes of soil and leaf (called 'Leaf/Soil'), soil and leaf attributes that have the highest Pearson correlation with yield, S (leaf), MO (soil), S (soil), Zn (leaf), Ca (leaf), K (leaf), T (soil), P (leaf), B (soil) and C (soil); and, finally, only the chemical attributes of leaf with the highest Pearson correlation, namely: S (leaf), Zn (leaf), Ca (leaf), K (leaf), and P (leaf ).…”
