Abstract
ABSTRACT Malva is the main Liberian species cultivated in Brazil, with production concentrated in the state of Amazonas, where its supports over 3,000 farming families along the floodplains of the Solimões and Amazonas Rivers. Cultivation remains entirely artisanal, with minimal technological input. This study aimed to evaluate optimal planting spacing for fiber production in the floodplain areas of Amazonas. Six spacings were tested along the Solimões River. We evaluated morpho-agronomic characteristics, biomass allocation, and the dry matter productivity of both aboveground biomass and fiber. Less dense spacings (25x25 cm and 25x20 cm) produced plants with greater aboveground volume but did not improve bark or dry fiber yield. The tested spacings also had no effect on allometric relationships. The proportion of dominated plants was lower in the less dense spacings, but the highest dry matter and fiber yields were observed in the 15x15 cm spacing, corresponding to an initial density of 43 plants m-2. Fiber yield under this spacing exceeded the average yields recorded for the crop, indicating that systematic planting at the 15x15 cm spacing is advantageous under the edaphoclimatic conditions of the study area.
