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 2 consecutive years i.e. 2020-21 and 2021-22. The study includes 14 treatments comprises different combination PGPMs, FYM and chemical fertilizers with two replications. The maximum fresh rhizome yield (13.32 kg plot-1 & 15.90 t ha-1) was registered with the application of NPK (150: 125: 150 kg ha-1) + FYM (10 t ha-1) + Trichokavach (Trichoderma asperellum, Pseudomonas fluorescens, Paecilomyces lilacinus and 2% chitosan- soil application @ 75 g plot-1 for 2 times at planting and 120 days after planting). Further, the same treatment registered significantly highest gross return (Rs. 31,80,000 ha-1), net return (Rs. 22,03,230 ha-1) and benefit: cost ratio (2.26) as compared to control.
