Abstract

Two disbudded, potted chrysanthemum cultivars were subirrigated with 9.25, 12.3, and 18.5 mM N during vegetative, but not reproductive growth. At commercial harvest, visible symptoms of N deficiency or differences in plant/inflorescence quality were minimal, whereas N uptake efficiency was dramatically improved at 9.25 and 12.3 mM N.
