Genotypic and Environmental Influence on Fresh Rhizome Yield of Turmeric (Curcuma longa L.)

Turmeric (Curcuma longa) and related Curcuma species have been used traditionally in India, China, Hawaii, other cultures for millennia. Today they are around the world spice, medicine, dye, religious purposes. Recent biomedical studies corroborated long-known traditional medicinal values of turmeric its constituent curcuminoid compounds, which anti-inflammatory, antioxidant, anticarcinogenic properties. As part statewide research extension efforts to support an expanding industry, we examined yield 14 accessions across different climatic zones Hawaii observe describe Genotype × Environmental influences. Fresh differed significantly among genotypes. The overall yields observed this work ranged 11.3–57.22 t ha?1 generally agree with those literature. Data from sites suggest that fertility water management able mitigate moderate stress imposed by climate change within a certain range, but suboptimal temperatures associated high elevation tropics (>1000 m) important driver lower yields. This suggests yielding varieties may possess wide adaptability perform well diverse environments. However, site-specific evaluations will still be necessary, particularly environments outside turmeric’s environmental optima presence pest pressure.
