About this variety
IISR Alleppey Supreme was released in 2004 by the Indian Institute of Spices Research (IISR) as an AFT (Alleppey Finger Turmeric) selection — a refinement of the Alleppey type of turmeric long prized for its deep colour and export value from the Alappuzha belt of Kerala. IISR's own variety page lists it for rainfed cultivation in Kerala and, under irrigated conditions, in Maharashtra, Karnataka and North Bengal as well — a wider spread than this page's existing Kerala/Karnataka listing. Its curcumin content is rated at 5.5% and oleoresin at 16%, both strong figures that back up this page's "high curcumin" note, with reddish-orange rhizomes and about 19% dry recovery. The variety reaches maturity in about 210 days, matching the lower end of this page's existing duration band. Its IISR-stated fresh-rhizome yield potential is 19.94 t/ha (about 199.4 q/ha) and 5.28 t/ha dry — noticeably lower than this page's existing "250–300 q/ha" figure, which more likely reflects a broader on-farm range than IISR's own trial-station potential-yield number.

Advantages & considerations
Things to consider
- Corrected 2026-08-15: IISR's own directly-fetched variety page lists a wider adoption footprint than this page's old Kerala/Karnataka states field — states corrected to add Maharashtra and West Bengal (North Bengal, where IISR reports irrigated cultivation, is a region within West Bengal, not tracked separately in this file's states fields, so it is folded into the West Bengal entry).
- IISR's stated fresh-rhizome yield potential (19.94 t/ha ≈ 199.4 q/ha) is meaningfully lower than this page's existing "250–300 q/ha" figure; the existing figure likely reflects a broader on-farm range rather than IISR's own trial-station number, but the gap is real and worth flagging.
- IISR's page names leaf blotch (Taphrina maculans) tolerance specifically, without separately confirming rhizome-rot resistance — this page's "Moderate" disease-resistance rating is broad enough to remain compatible with that.
