Resumo: dc.description.abstractThe species Dioscerea trifida, popularly known as “cará-roxo” is a highly appreciated species in the northern region of Brazil, representing great food and economic importance, especially in the state of Amazonas. However, there is a great lack of technological packages aimed at cultivating this species, especially in relation to fertilizer recommendations. Therefore, the objective of this study was to evaluate the production characteristics of purple yam under the influence of organic and phosphate fertilization in Itacoatiara-AM. The experiment was conducted in the experimental field belonging to the Institute of Exact Sciences and Technology – ICET/UFAM. The experimental design was in randomized blocks (DBC), in a 3x4 factorial scheme, with 3 doses of cattle manure (0, 10 and 20 t/ha) and 4 doses of phosphate fertilizer (0, 60, 120, 180 kg of P2O5/ ha), distributed in 3 replications and 5 plants per experimental unit, totaling 180 plants. Planting was carried out using whole and sanitized seed tubers, the holes measuring 0.40 x 0.40 x 0.30 m and during the crop cycle, irrigation was carried out with manual watering cans and regular weeding was carried out as necessary. Harvesting took place 9 months after planting and the variables analyzed were: average number of tubers per plant (NMTP), average tuber weight (PMT), total productivity of tuberous roots (PTRT), Commercial productivity (PC), length of tuberous roots (CRT), diameter of tuberous roots (DRT), dry biomass of roots (BSRT), dry biomass of leaves and stem (BSFC). The data were subjected to analysis of variance and comparison between means using the Tukey test at 5% probability. Regression analysis was performed depending on the P dosages for the evaluated characteristics. The analyzes were carried out with the aid of the statistical software R. From the results obtained, it is inferred that under the soil and climatic conditions of this experiment, fertilization with cattle manure and phosphate fertilizers did not significantly influence the productivity of the purple yam plant.pt_BR
