| Abstract | ||
| Black pepper is economically the most widely used spice crop around the world. Its cultivation is limited by the nursery's low success rate of vine cuttings. Appropriate growing media and uninfected cuttings could improve its establishment. Hence, this study investigates black pepper vine-cutting establishments using different growing media and disinfectants. A 2×5 factorial experiment involving two growing media [100% Soil and Sawdust+Soil (1:1)] and five disinfectants (Aloe vera, 10% HgCl2, 20% Hypochlorite, 70% Ethanol, 100% Ethanol) were evaluated in a randomised complete design with five replicates. Data on days to sprouting, percentage of mortality, and days to dieback were subjected to analysis of variance and significantly different means were separated (p<0.05). Black pepper vines established in 100% Soil (26.91) had significantly earlier days of sprouting than Soil+Sawdust (38.31). The HgCl2-treated vines sprouted significantly earlier than Hypochlorite, while others were similar. Combining 100% Soil and HgCl2 promoted the earliest days of sprouting. The 100% Soil and HgCl2 treatments significantly lowered mortality compared to Soil+Sawdust and other disinfectants. Vine mortality ranged from 0.00% (Soil × HgCl2) to 60.00% Sawdust+Soil × Hypochlorite and Sawdust+Soil × 70% Ethanol. Vines in Sawdust+Soil (17.00) had shorter days to dieback than 100% Soil (21.67). Aloe vera treatment had no dieback. Days to dieback range from 0.00 (Soil × Aloe vera, Sawdust+Soil × 100% Ethanol and Soil × Hypochlorite) to 55.67 (Soil × 70% Ethanol) for the interaction effect. The 100% Soil with 10% mercuric chloride was most suitable for establishing black pepper vines. | ||
