Heatmap clustering of irrigation regime (FC100, 100% field capacity; FC75, 75% field capacity; FC50, 50% field capacity) and fertilizer application (C control, HA humic acid, B bacterial, AA amino acid) sources based on essential oil constituents in in summer savory (Satureja hortensis L.). The key color bar indicates standardized mean values (dark red indicates relatively low mean values; dark blue indicates relatively high mean values).
