Abstract
Roselle plant (Hibiscus sabdariffa L.) is one of the important vegetables in which almost all parts of the plant are essential sources of food, raw materials used in many industries. To facilitate modern-day planting operations of Roselle seeds for bountiful crop production, planters could be used, just like any other seed. These planters are designed based on some physical properties of the seeds. In this review paper, some physical properties of Roselle seeds and other related seeds were gathered and examined because they are relevant in the perfect development of the seed planter.
Keywords: Roselle seeds, physical and mechanical properties, design, seed planters
