- Abstract
Widely used in various countries, roselle (Hibiscus sabdariffa) is used for culinary, medicinal, and ornamental purposes. Due to the growing need for more nutritious foods free of toxic substances and aiming at the development of environmentally-correct alternatives, this study aimed to evaluate the growth, development, and physicochemical quality of roselle under organic compost levels. The experiment was conducted at the Horticulture Unit of the Federal University of Acre, consisting of the application of four levels of organic compost, corresponding to the following treatments: T1 - 0 (control), T2 - 200 mL, T3 - 400 mL, and T4 - 600 mL, deposited into planting holes spaced 0.5 m in three planting rows approximately 10 m long and spaced by 1 m. The experimental design was in randomized blocks, with five blocks. The data were subjected to regression analysis at 5% of probability. The growth, production, and physicochemical quality variables of the leaves were analyzed. Significant results were obtained for plant height and the number of branches, with the levels of 325 mL and 142 mL standing out as the best to provide the highest plant height (276 cm) and number of branches (14), respectively. There was no significant difference between the compost levels and the production parameters and physiochemical analyses of the leaves. The organic compost promoted the growth in height and the number of branches of Hibiscus sabdariffa.
