📊 Repere fiziologice — Leuștean

Cultură / taxon: Leuștean · Levisticum officinale W.D.J.Koch

Rol agronomic: Lovage is leafy and responds to fertilization, but quality parameters also change with fertilizer treatment.

Mod de aplicare: 300–500 L/ha

Condiție de aplicare: soil/tissue + intended leaf/root use

Obiectiv: establishment and leaf area

Risc descris: excess fertility may alter nitrate and composition

Cultură / taxon: Leuștean · Levisticum officinale W.D.J.Koch

Rol agronomic: Fertilization changes dried-material quality and chemical composition; no universal high-N target is justified.

Mod de aplicare: 300–500 L/ha

Condiție de aplicare: nitrate/leaf quality + vigor

Obiectiv: high usable leaf biomass

Risc descris: more N may not equal better dried-herb quality

Cultură / taxon: Leuștean · Levisticum officinale W.D.J.Koch

Rol agronomic: For leaf market, harvest timing relative to flowering is a quality decision before nutrition.

Mod de aplicare: 300–500 L/ha

Condiție de aplicare: harvest use + bolting status

Obiectiv: leaf quality before flowering

Risc descris: late N can prolong soft growth and increase nitrate risk

Cultură / taxon: Leuștean · Levisticum officinale W.D.J.Koch

Rol agronomic: Food-crop surface residue and response window dominate.

Mod de aplicare: —

Condiție de aplicare: preharvest hygiene + harvest interval

Obiectiv: clean culinary material

Risc descris: late foliar has low return and can leave salts

Cultură / taxon: Leuștean · Levisticum officinale W.D.J.Koch

Rol agronomic: Lovage root and aerial tissues have distinct phytochemical profiles; repeated cutting changes source–sink balance.

Mod de aplicare: 300–500 L/ha

Condiție de aplicare: regrowth vigor + number of cuts + season length

Obiectiv: sustainable repeat harvest

Risc descris: forcing regrowth with N can weaken perennial reserve/hardening
