KAU Releases Five High-Yielding Varieties Spanning Chilli, Brahmi, Vetiver, Ginger and Turmeric

The Kerala Agricultural University has secured approval for five crop varieties from the 29th Kerala State Seed Sub-Committee — a significant step that clears the path for formal commercial cultivation across the state. The committee, chaired by Tinku Biswal, Agricultural Production Commissioner and Principal Secretary, Agriculture, gave its nod in June 2026.

The five varieties span vegetables, medicinal and aromatic plants, and spices: KAU Thejaswini (chilli), KAU Medha (brahmi), KAU Sougandhika (vetiver), KAU Cochin Pride (ginger), and KAU Golden Finger (turmeric). Each has been developed to suit Kerala's specific agro-climatic conditions, with the university emphasising higher productivity, quality improvement, and better farm-gate economics as the primary design goals.

KAU Thejaswini, developed by Sharada S., Associate Professor and Head, Department of Vegetable Science, College of Agriculture, Vellayani, is a long-fruited chilli variety recommended for cultivation across the entire state. Its bushy plants bear smooth, glossy fruits that are dark green at maturity and turn red on ripening. The variety carries medium pungency, field tolerance to viral diseases and bacterial wilt, and an average yield of 32.5 tonnes per hectare.

KAU Medha, a brahmi (Bacopa monnieri) variety developed by Ancy Joseph, Professor and Head, Aromatic and Medicinal Plants Research Station, Odakkali, is suited to central Kerala. Its key selling point is the combination of high biomass and elevated bacoside content — the medicinal compound that gives brahmi its market value. Under open, well-lit conditions the variety yields 34–36 tonnes of fresh herbage and 5–6 tonnes of dried produce per hectare, with anthocyanin pigmentation developing on stems around 80 days after planting.

Also developed by Ancy Joseph at Odakkali, KAU Sougandhika (ODV 27) is a new vetiver (ramacham) variety engineered for root and essential oil production in the open areas of central Kerala.

Key agronomic traits include:

• Vigorous growth with profuse tillering and delayed flowering
• Thick, long, aromatic roots yielding 6.1–7.8 tonnes of dry root per hectare
• Essential oil content of 1.4%, making it commercially attractive for the fragrance and personal-care industries

Vetiver cultivation has traditionally provided supplementary income for small and marginal farmers in Kerala, and a variety offering both high root biomass and strong oil content could meaningfully improve returns from existing land under this crop.

KAU Cochin Pride, developed by Nair Sunil Appukuttan, Assistant Professor, Department of Plantation Crops and Spices, College of Agriculture, Vellanikkara, is designed to revive the premium positioning of traditional Cochin ginger. The variety retains the characteristic pungency and aroma associated with that heritage crop while delivering higher zingiberene and starch content. It matures in 240–245 days, resists rhizome rot, and can be grown as a sole crop or intercropped in coconut plantations. Average yield stands at 36.3 tonnes per hectare; the variety has been specifically recommended for dry ginger production in Kottayam and Idukki districts.

KAU Golden Finger (KAU AFT 31), also by Dr. Appukuttan and developed with financial support from the Directorate of Arecanut and Spices Development, Kozhikode, is a high-curcumin Alappuzha Finger turmeric variety with 8.65% curcumin content, deep orange flesh, and export-quality rhizomes. It matures in 240–250 days and yields 39–42 tonnes of fresh turmeric per hectare, with recommendation for cultivation in Kottayam district.

Taken together, the five varieties address distinct segments of Kerala's agricultural economy — from fresh vegetables and functional foods to spices destined for both domestic consumption and export.

For farmers

Disease tolerance (bacterial wilt resistance in chilli, rhizome rot resistance in ginger) reduces crop-loss risk, while yield improvements across all five varieties expand the revenue ceiling per hectare without requiring additional land.

For traders and processors

The high-curcumin specification in KAU Golden Finger and the preserved heritage aroma profile of KAU Cochin Pride directly address buyer quality requirements in export and processed-food markets.

For the broader sector

The involvement of the Directorate of Arecanut and Spices Development as a funding partner in the turmeric variety underscores the increasingly collaborative model between public research institutions and government commodity boards — a template worth watching as India's spice export ambitions grow.
