Abstract:
Black turmeric (Curcuma caesia Roxb.) is a perennial herb belongs to Zingiberaceae family, usually found in N-E and Central India. It is an endangered species which includes many medicinal properties which possess several uses in pharmaceutical and cosmetic industry. The studies on agronomical requirements of the crop are scarce. Hence the present study on “Influence of PGPM and INM on yield and economics in black turmeric” was carried out at College of Horticulture, Bengaluru during the year 2021-22. The study includes 14 treatments comprises different combination PGPMs, FYM and chemical fertilizers with two replications. The maximum essential oil content (0.51%) was registered with the application of EMC3- AM fungi- Glomus spp (1 g plant^-1), Azospirillum, P. fluorescens, Trichoderma, PSB and KMB @ 10 ml L^-1 each + FYM (10 t ha^-1) + 125% of RDF. Further, the treatments consist both organic and inorganic fertilizers coupled with bio fertilizers proved best for enhanced secondary metabolites. In that, T₁₀ recorded maximum camphene (3.35%) content in the essential oil extracted from fresh rhizomes.
