Optimising plant growth, biomass partitioning, and nitrogen use efficiency in taro (Colocasia esculenta (L.) Schott)

Puntos clave

Maximizing corm biomass occurs at an optimal nitrogen level of around 10 mM N, without sacrificing quality.
Nutritional quality remains intact while growing taro at the optimized nitrogen level identified.
Observational analysis demonstrated how nitrogen levels impact biomass partitioning and growth efficiency.
These insights may enhance the viability of taro as a crop for improving nutrition security.

Resumen

Hypotheses 2 and 3 were supported; Hypothesis 1 was not. The optimal N level for maximizing corm biomass without compromising nutritional quality is around 10 mM N. These findings will inform biophysical models for taro to help its development as a food and nutrition security crop.
