ResumoJambu [Acmella oleracea (L.) R. K. Jansen] is a leaf vegetable native to the Amazon, being very used for cookery, traditional medicine treatments, and both cosmetic and pharmaceutical industry. Despite its growing adoption, this leaf vegetable still lacks more precise information about its cultivation. Based on this, this study aimed to evaluate the influence of spacing and density of plants per cultivation hole in the growth and production of jambu. The experiment was conducted in the vegetable garden of the Universidade Federal do Ceará, Fortaleza, Ceará, Brazil. The study used randomized block with split plot design and three replications. The plots correspond to two different spacings: 0.20 × 0.20 m, and 0.25 × 0.25 m, and subplots correspond to five different amounts of plants per hole: three, five, seven, nine and twelve plants. The following parameters were measured: length of shoots, length of roots, number of leaves, leaf area, fresh weight of shoots and roots, dry weight of shoots and roots, fresh mass yield and gas exchange. Interaction effects between spacing and number of plants per hole was not observed. Spacing did not interfere in the measured variables for individual plants; however, the number of plants per hole interfered in growth, which can be described through a decreasing linear function for almost all measured variables. The 0.2 × 0.2 m spacing, associated with the highest number of plants per hole – twelve plants – leads to the highest yield per area of jambu.
