Effects of natural environmental factors on growth and tuber production of Tacca leontopetaloides (Polynesian arrowroot), an underutilized food crop

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Tacca's productivity in dry tropical zones increases with rainfall and land cover gradients. Phosphorus (P) content in soil is positively correlated with plant aboveground growth traits (total height, leaf area) and tuber weight of the species, whereas potassium (K) is correlated only with tuber weight.
