Kenaf (Hibiscus cannabinus L.) is a plant fiber with high cellulose content, used for livestock feed and making rope, carpet, and twine. The future of kenaf cultivation in Bangladesh looks promising due to its industrial uses and environmental benefits. Increasing kenaf seed production in Bangladesh can ensure a steady supply and support the industry and sustainability. Keeping this view in mind, the study was conducted at the Jute Research Substation in Kalapara, Patuakhali, from September 2022 to February 2023, to determine the optimal planting geometry and method for Kenaf seed production in coastal areas. The experiment used a completely randomized block design (RCBD) with three replications, including three row-to-row distances (30 cm, 40 cm, and 50 cm) and four plant-to-plant distances (continuous line sowing, 10 cm, 15 cm, and 20 cm). The results showed significant differences in yield and yield attributes due to planting geometry and methods. The highest seed yield (138.09 g per square meter) was achieved with seedlings transplanted at 40 cm row spacing and 15 cm plant spacing. This configuration also positively influenced plant height, base diameter, number of pods per plant, number of seeds per pod, and 1000-seed weight. Seed germination percentage, seed vigor index (SVI), germination percentage after accelerated aging (AA), and electrical conductivity (EC) values were significantly affected by the interaction of planting geometry and method. The highest germination percentage (98%), SVI (47.01), and germination percentage after AA (71.45) were recorded for the 40 cm row and 15 cm plant spacing, while the lowest EC value (19.46 µS cm-1 g-1) was observed at 30 cm row and 10 cm plant spacing. Therefore, for optimal seed yield, seed quality, and economic benefits, transplanting Kenaf seedlings at 40 cm row and 15 cm plant spacing is recommended.
Keywords: Kenaf, planting geometry, planting method, seed yield and accelerated ageing.
