Abstract Winged bean (Psophocarpus tetragonolobus (L) DC) accessions showed exponential growth 10 days after planting (DAP) in a NFT hydroponic system. Flowering increased exponentially following the onset of short daylength but 86–94% of flowers abscissed. Leaves accounted for 26–34%, stems 49–52%, and roots 15–17% of total biomass. Ion concentration in the nutrient solution declined within 5 days of replenishment. Roots accumulated higher concentrations of Ca, K, P, Fe, and Mn than aerial parts of the plant; levels of P and Fe in leaves were similar to soil grown plants whilst hydroponically grown plants had higher levels of Ca in leaves, K in green pods, P in tubers, and Fe in flowers. Plants with a dwarf habit (GRWB-11) reverted to indeterminate growth in NFT.
