The dominant multi-purpose legume tree across sub-Saharan Africa, Sesbania sesban delivers simultaneous benefits in livestock fodder, soil nitrogen fixation, and agroforestry systems. Kohenoor International exports premium-grade sesbania sesban seeds with 82%+ germination and 97%+ purity to agricultural programs, NGOs, and commercial buyers worldwide.
Sesbania sesban (syn. Sesbania aegyptiaca) is the most widely cultivated Sesbania species across sub-Saharan Africa, where it has become indispensable in smallholder farming systems from the Ethiopian highlands to the savannas of West Africa. Unlike annual Sesbania varieties that complete their lifecycle in a single season, S. sesban is a fast-growing, short-lived perennial shrub or small tree that can persist for 3-5 years under favorable conditions, producing continuous biomass for fodder, fuelwood, and soil fertility replenishment.
As a multi-purpose agroforestry species, sesbania sesban fills a critical gap in tropical farming: it grows rapidly on degraded soils where few other legumes survive, fixes atmospheric nitrogen at rates comparable to synthetic fertilizer application, and produces high-protein foliage that livestock readily browse. Research stations across Kenya (ICRAF), Ethiopia (ILRI), and Malawi (CIMMYT) have validated its performance in improved fallow rotations, consistently demonstrating 100-200% yield increases in subsequent maize and sorghum crops.
Kohenoor International sources and processes sesbania sesban seeds under strict quality controls, ensuring each lot meets the germination and purity thresholds required by institutional buyers and government agricultural programs.

Across sub-Saharan Africa, sesbania sesban has emerged as the backbone species for soil fertility replenishment programs addressing chronic nutrient depletion. Decades of continuous cropping without adequate fertilization have left millions of hectares nitrogen-deficient, directly limiting food production for smallholder farmers who cannot afford synthetic inputs.
In the highlands of western Kenya, the improved fallow system pioneered by the World Agroforestry Centre (ICRAF) relies primarily on Sesbania sesban. Farmers plant S. sesban on exhausted plots for 1-2 seasons, allowing the trees to fix nitrogen and deposit nutrient-rich leaf litter. When cleared, the rejuvenated soil supports maize yields of 3-4 tonnes per hectare compared to 1-1.5 tonnes on unfertilized land. Ethiopia's national reforestation programs include S. sesban in watershed rehabilitation, while Tanzanian livestock keepers use it as a dry-season protein supplement for dairy cattle.
In the Guinea savanna zones of Nigeria and Ghana, sesbania sesban is integrated into alley cropping systems where rows of S. sesban are planted at 4-6 meter intervals between food crops. Periodic pruning generates mulch that suppresses weeds and releases nutrients directly into the crop root zone. Nigerian research trials have documented 60-80 kg N/ha contributed by S. sesban hedgerows in a single growing season, substantially reducing fertilizer expenditure for smallholders growing maize, sorghum, and millet.
Sesbania sesban foliage contains 18-22% crude protein on a dry matter basis, rivaling commercial concentrates. Cattle, goats, and sheep readily consume the leaves and young stems. In East African dairy systems, supplementing lactating cows with S. sesban browse increases milk yield by 15-25% during the dry season when grass quality drops below maintenance requirements.
Through symbiotic nitrogen fixation, S. sesban adds 100-200 kg N/ha/year to the soil profile. Root decomposition also improves soil structure, increases water infiltration, and stimulates beneficial mycorrhizal fungi. Improved fallow with S. sesban is the most cost-effective green manure strategy for resource-poor farmers in tropical Africa.
The fast growth rate of S. sesban produces harvestable fuelwood within 12-18 months. A single hectare of dense S. sesban plantation can yield 8-15 tonnes of wood per year, reducing pressure on natural forests. The wood burns with moderate heat and low smoke, making it suitable for household cooking and small-scale charcoal production.
Planted in rows along field boundaries, sesbania sesban provides effective windbreak protection for annual crops, reducing wind erosion and evapotranspiration. In East African coffee and tea estates, S. sesban serves as temporary shade during establishment, protecting young seedlings from direct sunlight while simultaneously enriching the soil through nitrogen fixation and leaf fall.
Sesbania sesban thrives in tropical and subtropical climates with mean annual temperatures of 20-30 degrees C and rainfall ranging from 500-2,000 mm per year. It tolerates seasonal drought once established but performs best with consistent moisture during the first 3 months. S. sesban does not survive hard frost, limiting its range to altitudes below 2,000 meters in equatorial regions.
This species adapts to a remarkably broad soil pH range of 5.0-8.5, from acidic lateritic soils to moderately alkaline vertisols. It performs well on sandy loams, clay loams, and alluvial soils. Its tolerance for saline conditions (up to EC 5-7 dS/m) makes it valuable for rehabilitating salt-affected land in arid and semi-arid zones.
Sesbania sesban seeds have a hard seed coat that inhibits water absorption. Before sowing, treat seeds by soaking in hot water (80 degrees C) for 3 minutes, then allow them to cool in the water for 12-24 hours. Alternatively, mechanical scarification with sandpaper or brief acid treatment (concentrated sulfuric acid for 10-15 minutes) achieves 90%+ germination. For detailed instructions, see our guide on How to Germinate Sesbania Seeds.
For improved fallow, broadcast seeds at 15-20 kg/ha onto a prepared seedbed at 2-3 cm depth. For alley cropping hedgerows, sow at 5-10 kg/ha in rows spaced 4-6 m apart with 25-50 cm between plants within rows. For fodder banks, plant at 20-30 kg/ha with row spacing of 50-75 cm. Direct seeding is standard; nursery-raised seedlings are used only for high-value agroforestry plantings.
First leaf harvest is possible at 70-100 days after sowing. For fodder, cut stems at 50-75 cm above ground level to promote regrowth. S. sesban tolerates 3-4 cuttings per year under favorable moisture conditions. For improved fallow, allow trees to grow for 12-24 months before clearing and incorporating residues into the soil prior to food crop planting.
Kohenoor International supplies sesbania sesban seeds to institutional and commercial buyers across the following priority regions:
Sesbania sesban fixes 100-200 kg of atmospheric nitrogen per hectare annually through root nodule symbiosis with Rhizobium bacteria. In improved fallow systems widely practiced across Kenya, Malawi, and Zambia, farmers grow S. sesban for 1-2 years on degraded plots, then clear and crop the land. The decomposing roots and leaf litter release nitrogen, phosphorus, and organic carbon, often doubling maize yields compared to unfertilized continuous cropping.
Yes, Sesbania sesban demonstrates moderate to high salt tolerance, performing well in soils with electrical conductivity (EC) up to 5-7 dS/m. It can also tolerate alkaline pH up to 8.5. This makes it a valuable species for rehabilitating salt-affected and degraded lands in arid and semi-arid regions of East Africa and the Mediterranean. Learn more about salt-tolerant crops in our Sesbania for Salt-Tolerant Agriculture guide.
For agroforestry hedgerows and alley cropping, sow Sesbania sesban at 5-10 kg per hectare with row spacing of 4-6 meters between alleys. For improved fallow plantations, broadcast at 15-20 kg per hectare. For high-density fodder banks, increase the rate to 20-30 kg per hectare with closer row spacing of 50-75 cm. Seeds should be scarified or soaked in hot water (80 degrees C for 3 minutes) before sowing to break physical dormancy.
