A drought-tolerant staple across West Africa and the semi-arid tropics, and a protein backbone for hundreds of millions of people.

what cowpea can fix on poor, dry land — a strong fixer, when nodulation holds through heat and drought.
Cowpea is usually grown on poor, dry soils where native rhizobia are variable; under heat and drought, nodulation and nitrogen supply fall short of the crop’s potential.
Cowpea feeds hundreds of millions across West Africa and the semi-arid tropics, thriving on land where few other crops will — a quiet staple of food security.
It is usually sown on poor, dry soils where native rhizobia are patchy and variable, so strong nodulation is far from guaranteed — even for a naturally capable fixer.
Under the stress cowpea is planted into, nodulation and nitrogen supply fall short of the crop’s real potential, right when the plant can least afford it.
A crop-matched program led by the Orvan™ coupling, backed by a region-specific rhizobium (Nodu™) and phosphate-solubilizing, stress-tolerance PGPR (Vigor™). Each is field-proven and available on its own.
Rhizosphere coordination consortium
Nitrogen-fixation potentiation — applied alongside your rhizobial inoculant. Orvan™ carries no rhizobia of its own; it amplifies the ones already adapted to your soil.
Rhizobial inoculant
The region-matched, nitrogen-fixing rhizobia your crop needs — so it fixes more of its own nitrogen and you buy less.
PGPR — phosphorus & stress
Frees bound soil phosphorus, builds stronger roots, and buffers drought and salinity stress — the second leg of the consortium.

Orvan™ field trials · Cowpea · vs. untreated control
Across 48 sites in 5 provinces (Henan, Hubei, Guangxi; 2021–2024): +13.8% average yield, up to 5.2× more nodules, nitrogenase up to 4.4×, and up to 115 kg N/ha fixed, holding yield through heat and drought.
