From: Integrating Narcissus-derived galanthamine production into traditional upland farming systems
Effect of fertiliser application and cutting history on (a) estimated biomass yields of Narcissus pseudonarcissus cv Carlton, and (b) corresponding galanthamine yields in 2018 (where cut = harvested the previous year; not cut = no harvest the previous year; Daff/full = compound fertiliser applied at a rate of 50 kgN/ha, 25 kgP/ha and 25 kgK/ha; Daff/half = compound fertiliser applied at a rate of 25 kg N/ha, 12.5 kg P/ha and 12.5 kg K/ha; error bars = s.e.d.).
