A field experiment was conducted to study the response of galangal (Kaempferia galanga), grown as intercrop, to agronomic practices in coconut garden during 1995-98. The chlorophyll and carotenoid content did not differ significantly when mother rhizome and finger rhizome used as planting material. Plant population levels of 333,000 and 500,000/ha had the same effect with respect to chlorophyll and carotenoid contents. Organic manures like farmyard manure (FYM), vermicompost (VC) and combination of FYM + NPK and NPK , applied alone had significantly higher chlorophyll and carotenoid content. The total dry-matter production increased significantly when mother rhizome, with 333,000/ha population, was used as planting material. Among organic manure treatments, FYM, VC and FYM+NPK significantly contributed to the increase in dry matter compared to composted coir pith (CCP) and NPK treatments. Fresh-rhizome yield was significantly superior with mother rhizome and with 500,000 population level. FYM + NPK combination recorded significantly higher fresh-rhizome yield. The harvest index improved significantly with mother rhizome treatment and at 333,000/ha population. Among organic manures, FYM, VC,FYM+NPK and NPK improved harvest indices compared to CCP and control treatments.
