Our study aimed to evaluate dry matter production and both extraction and export of macronutrients by arrowroots (Maranta arundinacea L.) to be used in further crop fertilization plans. To this purpose, two experiments were carried out in field conditions using the varieties Viçosa and Seta. The experimental design was randomized with four replications and nine periods of analysis, which were defined as days after planting (105, 135, 165, 195, 225, 255, 285, 315, and 345 DAP). Dry matter, extraction, and export of macronutrients by arrowroot seed-rhizomes, aerial parts, roots, and storage roots (rhizomes) were determined. The exports of N, P, K, Ca, Mg, and S of storage rhizomes of the variety Viçosa were 104.6, 51.83, 412.24, 15.85, 36.14, and 64.36 kg ha-1, while those of the seta variety were 160.6, 71.62, 521.31, 17.57, 60.09, and 160.41 kg ha-1, respectively. Both varieties proved to be efficient soil macronutrient extractors, mainly for K. The variety Seta had higher shoot, root, seed-rhizome dry matter contents, as well as greater macronutrient extractions and exports. 2023 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303075473036 https://www.redalyc.org/journal/3030/303075473036/ https://www.redalyc.org/journal/3030/303075473036/html/ https://www.redalyc.org/journal/3030/303075473036/303075473036.epub https://www.redalyc.org/journal/3030/303075473036/movil 10.4025/actasciagron.v45i1.58132 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
