Spices like black pepper, cardamom, tree spices such nutmeg, cinnamon, clove are perennials and ginger and turmeric are grown annually. Most of them are propagated by vegetative methods. Non- availability of quality planting material is one of the important production constraints that affect the area expansion or gap filling programmes. Each crop requires specific techniques and handling to produces for planting material production from proven mother plants. The black pepper cuttings collected from mother plant are further multiplied by employing suitable rapid multiplication techniques. The simple and fast techniques are ‘soil mound’ with multiplication ratio of 1:40 in a year for production of normal cuttings. The micro propagated ginger can be raised using soil less medium in 18 or 20 well protrays, which is easy for transport and ensure pathogen free. In cardamom, vegetative techniques with average production of 32-42 suckers after 12 months of planting from one planting unite. Cardamom and turmeric are propagated through rhizome, around 1500 kg/ha seed is required and this can be reduced by adopting novel single bud transplanting is popular with several advantages. In tree spices nutmeg and kokum propagated through softwood grafting and cinnamon by layering. Bush pepper and dwarf grafts are suitable urban horticulture and vertical farming. Use of growth regulators, ideal potting mixture and fortification with PGPR’s or bio-control agents enhance seedlings vigour. By adopting these efficient multiplication techniques we can meet the quality planting material requirements of spices.
