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

Taro (Colocasia esculenta) is the fourth most important root crop globally, yet it remains understudied. Productivity is frequently constrained by nutrient-depleted soils This study investigates how varying nitrogen (N) levels affect taro growth, particularly biomass accumulation, sucker production, and the formation of calcium oxalate raphides, which can be harmful when ingested. Taro plants were grown in nutrient solutions with N concentrations ranging from 2.5 to 20 mM. They were harvested at different growth stages up to 10 months to capture corm formation, filling, maturity and post-maturity stages Biomass and nutrient concentrations were measured, and nitrogen use indices were calculated.
