ABSTRACT
This study was conducted to determine the potential of raising roselle (Hibiscus sabdariffa L.) seedlings, using different types of coarse and sieved media in various pot sizes up to thirty days after germination. Roselle seeds of cultivar 'Locale' and formulated rooting media were characterized for certain physico-chemical characteristics. The media were different in terms of pH, electrical conductivity (EC), container capacity and percent aeration porosity (p<0.05). Root dry weight (DW) of roselle seedlings differed significantly among rooting media (p<0.05) and pot sizes (p<0.05). Root DW of roselle seedlings from medium M4 (2-mm sieved scoria) was 0.188�0.046 g, while under the control treatment (soil), root DW was much lower (0.069�0.020 g). Number of leaves and shoot DW of seedlings from M4 treatment were considerably higher than the control seedlings. An interaction effect between type of media and pot size on the whole seedling DW (p<0.05) was also observed. Pot size P1 produced roselle seedlings of higher seedling DW in the coarse media. Under sieved media, pot sizes differed in shoot DW (p<0.05), whereby P2 and P3 produced roselle seedlings of higher seedling DW than P1. Scoria has the potential as soilless substrate for roselle seedling production.
