Resumen
Descripción
The investigation was carried out at the National Institute of Agricultural Sciences (INCA), within summer 2001, with the objective of comparing six plantation distances in the cultivation of Jamaica (Hibiscus sabdariffa L .) and its influence on yield and its components per area to define the best density. Distances were: 1.20x1.00 m; 1.20x0.90 m; 1.00x1.00 m; 1.00x0.90 m; 0.90x0.90 m and 0.90x0.80 m; to those plantation frames corresponded the following densities: 8 333, 9 260, 10 000, 11 111, 12 345 and 13 888 plants.ha -1 . A randomized block design with four repetitions was used, evaluating fruit weight plus fresh and dry calyxes separatedly. Data were processed by means of a One-Way Classification Variance Analysis, recording significant differences among treatments. Results showed yield performance corresponded with plant densities, thus obtaining 4.5 t.ha -1 with the lowest and 7.53 t.ha -1 with the highest densities of fresh calyxes.
