High Photosynthetic Photon Flux Density Differentially Improves Edible Biomass Space Use Efficacy in Edamame and Dwarf Tomato.

ABSTRACT: Improving edible biomass space use efficacy (EBSUE) is important for sustainably producing edamame and dwarf tomatoes in plant factories with artificial light. Photosynthetic photon flux density (PPFD) may increase EBSUE and space use efficacy (SUE). However, no study has quantitatively explained how PPFD affects EBSUE in edamame and dwarf tomatoes. This study aimed to quantitatively validate the effects of PPFD on EBSUE in dwarf tomatoes and edamame and verify whether this effect differs between these crops. The edamame and dwarf tomato cultivars 'Enrei' and 'Micro-Tom', respectively, were cultivated under treatments with PPFDs of 300, 500, and 700 µmol m^-2 s^-1. The results showed that the EBSUE and SUE increased with increasing PPFD in both crops. The EBSUE increase
