Sourced and exported from Pakistan since 1957, Kohenoor International supplies high-purity Sesbania bispinosa seeds to agricultural importers, government agencies, and farming cooperatives across Asia, Africa, and South America.
Sesbania bispinosa, widely known as Dhaincha across South Asia, is the primary variety selected for green manure applications in waterlogged rice paddies and lowland farming systems. This fast-growing annual legume thrives in conditions where most other green manure crops fail — standing water, saline soils, and marginal lands that would otherwise remain unproductive between cropping seasons.
Dhaincha seeds from Kohenoor International are carefully cleaned, graded, and tested to meet international seed quality standards. Every lot undergoes laboratory analysis before shipment, ensuring buyers receive consistent quality shipment after shipment. Our dhaincha seeds for sale are available year-round from our warehouses in Lahore, Pakistan, with flexible packaging and rapid dispatch for both full container loads and LCL orders.
Whether you need dhaincha green manure seed for large-scale rice cultivation programs, soil rehabilitation projects, or commercial gum extraction, Kohenoor International provides the seed quality, documentation, and export expertise that institutional buyers require.

Sesbania bispinosa fixes an impressive 150-200 kg of nitrogen per hectare through symbiotic Rhizobium nodulation. When incorporated as dhaincha green manure before rice transplanting, this biological nitrogen can replace 50-75% of the recommended urea dose, directly reducing input costs for farmers and lowering nitrous oxide emissions from synthetic fertilizers.
Unlike most leguminous cover crops, Sesbania bispinosa survives prolonged waterlogging up to 30 cm deep. Adventitious roots and aerenchyma tissue allow gas exchange even in saturated soils, making it uniquely suited for rice paddies, flood-prone lowlands, and irrigated farming systems throughout the monsoon belt.
Dhaincha produces 15-25 tonnes of fresh biomass per hectare within just 45-60 days. This rapid canopy closure suppresses weeds, adds organic matter to the soil, and improves soil structure through root channels. The high cellulose content also contributes to long-term humus formation.
The seeds of Sesbania bispinosa yield Sesbania gum (galactomannan), a valuable hydrocolloid used in textile sizing, paper manufacturing, mining flotation, oil drilling, and food-grade thickening applications. Seed-grade Dhaincha is increasingly in demand for industrial gum extraction alongside its agricultural uses.
Successful sesbania bispinosa cultivation begins with proper land preparation and timely sowing. Below are the recommended agronomic practices for achieving maximum biomass and nitrogen fixation.
Dhaincha grows on a wide range of soils including clay, loam, sandy loam, and saline-alkaline soils with pH 5.5-8.5. It performs best in moist lowland soils but will also establish on drained upland fields. Its tolerance for marginal soils makes it an excellent reclamation crop for salt-affected land.
Optimal growth occurs at 25-35°C. Sesbania bispinosa is a tropical and subtropical species and does not tolerate frost. It thrives in areas receiving 500-2,000 mm of annual rainfall and grows vigorously during the warm, wet monsoon season (June-September in South Asia).
Sow seeds at a depth of 2-3 cm in moist soil. For green manure, broadcast sowing at high density is standard. For row planting, maintain 25-30 cm between rows. No thinning is needed when the crop is destined for soil incorporation. For seed production, increase row spacing to 45-60 cm.
Apply 40-50 kg per hectare (16-20 kg per acre) for green manure purposes. For seed production fields, reduce the rate to 20-25 kg per hectare. Pre-soaking seeds in water for 12-24 hours improves germination uniformity — see our detailed guide on How to Germinate Sesbania Seeds.
Incorporate the crop into the soil 45-60 days after sowing, ideally at the 50% flowering stage for maximum nitrogen content. Use a disc plough or rotavator to chop and turn in the biomass at least 7-10 days before rice transplanting to allow initial decomposition.
The following table compares the crude protein content of Sesbania bispinosa foliage with common fodder crops, demonstrating its value as a high-protein supplementary feed.
| Fodder Crop | Crude Protein (% DM) | Digestibility (%) | Yield (t/ha Fresh) |
|---|---|---|---|
| Sesbania bispinosa (Dhaincha) | 20-25% | 55-65% | 15-25 |
| Lucerne / Alfalfa | 18-22% | 60-70% | 8-15 |
| Berseem Clover | 16-20% | 65-72% | 40-60 |
| Napier Grass | 8-12% | 55-60% | 60-80 |
| Sorghum (Fodder) | 7-10% | 50-58% | 30-50 |
| Maize (Fodder) | 8-10% | 60-68% | 35-55 |

We offer FOB Karachi, CFR, and CIF terms depending on destination. Typical lead time from order confirmation to vessel loading is 10-15 business days. For agricultural terminology used in seed trade, refer to our Sesbania Agricultural Glossary.
The recommended seed rate for Sesbania bispinosa is 40-50 kg per hectare (16-20 kg per acre) when used as green manure. For seed production, a lower rate of 20-25 kg per hectare is recommended with wider row spacing of 45-60 cm.
Sesbania bispinosa can fix between 150-200 kg of nitrogen per hectare when incorporated as green manure at 45-60 days after sowing. This biological nitrogen fixation significantly reduces the need for synthetic urea application in subsequent rice crops.
Yes, Sesbania bispinosa is exceptionally tolerant of waterlogging and can survive in standing water up to 30 cm deep. This makes it the preferred green manure crop for rice paddies and flood-prone lowland areas where other leguminous green manure crops fail.
All shipments from Kohenoor International include a Phytosanitary Certificate issued by the Department of Plant Protection (Government of Pakistan), a Fumigation Certificate, a Certificate of Origin (COO), and a seed quality test report from an accredited laboratory detailing germination, purity, and moisture content.
Sesbania bispinosa (Dhaincha) is an annual herbaceous plant primarily used for green manure and gum production, growing 2-3 meters tall. Sesbania grandiflora (Agati) is a perennial tree growing up to 10 meters, mainly used for fodder, edible flowers, and agroforestry. Bispinosa is better suited for short-rotation green manuring in rice-based cropping systems.
