Crop application data
A resilient, deep-rooted legume central to farming systems in India and East Africa. India alone grows about 63% of the world’s pigeon pea.
140 kg N/ha
what a well-nodulated pigeon pea can fix — over 90% of its vegetative nitrogen — most of it lost where native rhizobia are sparse.
A long-season crop with high cumulative nitrogen demand, usually grown in low-input smallholder systems where native rhizobia are often sparse, so much of its fixation potential goes uncaptured.
Deep-rooted and resilient, pigeon pea anchors cropping systems across India and East Africa; India alone grows about 63% of the world’s crop.
Its extended cycle builds a high cumulative nitrogen demand — a bill that only strong biological fixation can meet without heavy fertilizer.
In the low-input systems where it is raised, resident nodulating bacteria are often sparse, so most of the crop’s fixation potential goes uncaptured.
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 · Pigeon Pea · vs. untreated control
Across 36 sites in 4 provinces (Yunnan, Guangxi, Hainan; 2022–2024): +12.6% average yield, up to 4.1× more nodules, nitrogenase up to 3.8×, and up to 140 kg N/ha fixed, meeting over 90% of the crop’s vegetative nitrogen and leaving ~30–40 kg N/ha for the next crop.
