Sorghum & Fenugreek

Controlled Agronomic Validation | Drought • Salinity • Excess Water

Carrabiitol® was evaluated as an osmo-priming treatment in sorghum and fenugreek to determine its potential to support seed germination and early seedling establishment under challenging abiotic stress conditions.

The study demonstrated that Carrabiitol®-primed seeds maintained better germination, root and shoot development, and seedling vigour compared with non-primed seeds exposed to stress.

Key Agronomic Outcomes

+60% | +33%

Higher Germination Under Drought

Carrabiitol® at 3000 mg/L increased germination efficiency by 60% in sorghum and 33% in fenugreek compared with non-primed stressed seeds.

12.4× | 2.7×

Higher Seedling Vigour Under Drought

The vigour index of Carrabiitol®-primed seeds was 12.4-fold higher in sorghum and 2.7-fold higher in fenugreek compared with non-primed stressed seeds.

2.2× | 1.8×

Higher Vigour Under Salinity

At the evaluated salinity levels, Carrabiitol® priming resulted in a 2.2-fold higher vigour index in sorghum and 1.8-fold higher vigour index in fenugreek compared with non-primed stressed seeds.

Up to 6× | 5.7×

Improved Root Growth Under Excess Water Stress

Carrabiitol® priming enhanced root development under excess-water stress, with root length reaching up to 6-fold higher in sorghum and 5.7-fold higher in fenugreek compared with non-primed stressed seedlings under the corresponding conditions.

Building Resilience from Germination

The results indicate that Carrabiitol® osmo-priming can help mitigate the adverse effects of drought, salinity and excess-water stress during germination and early seedling development.

The study suggests that Carrabiitol® supports osmotic balance and cellular turgidity and may activate osmoprotective responses, contributing to improved germination and seedling establishment under stress.
