Unrivalled Nitrogen Fixation for Soil Regeneration
Sesbania is one of the most powerful biological nitrogen fixers known to modern agriculture. Research published by ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) confirms that sesbania species can fix between 80 and 300 kilograms of atmospheric nitrogen per hectare during a single growing season. This extraordinary capacity arises from a highly efficient symbiotic relationship with Rhizobium and Azorhizobium bacteria, which colonize both root and, in some species like S. rostrata, stem nodules. When sesbania biomass is incorporated into the soil as green manure, this biologically fixed nitrogen becomes available to subsequent cash crops such as rice, wheat, maize, and vegetables, reducing the need for synthetic urea fertilizer by up to 50%. According to FAO estimates, replacing just 30% of synthetic nitrogen with legume-derived biological nitrogen could save smallholder farmers $200-400 per hectare annually while simultaneously improving soil organic carbon levels. The environmental benefits are equally compelling: biological nitrogen fixation produces zero greenhouse gas emissions, unlike the Haber-Bosch process used to manufacture synthetic nitrogen fertilizer, which accounts for approximately 1.2% of global CO2 emissions. By choosing sesbania seeds from Kohenoor International, you invest in a proven, science-backed solution for sustainable soil fertility management that pays dividends season after season.

High-Value Industrial Gum Extraction
Beyond agriculture, sesbania seeds — particularly Sesbania bispinosa (commonly known as dhaincha) — serve as the primary raw material for sesbania gum, a galactomannan polysaccharide with exceptional industrial properties. The gum is extracted from the seed endosperm through a process of dehusking, splitting, and milling. Sesbania gum functions as a natural thickener, binder, and viscosifier across multiple industries. In paper manufacturing, it serves as a wet-end additive that improves sheet formation, increases burst strength, and enhances printability — paper mills in China, India, and Southeast Asia consume thousands of tonnes annually. In textile processing, sesbania gum acts as a warp sizing agent, providing the lubrication and film-forming properties needed to reduce yarn breakage during weaving. The mining sector uses sesbania gum as a flocculant in mineral processing, particularly in copper and gold extraction. In the oil and gas industry, it serves as a viscosifier in hydraulic fracturing fluids. According to USDA market reports, global demand for sesbania gum has been growing at approximately 12% per year, driven by expanding paper production in Asia and the shift toward bio-based industrial chemicals. For buyers interested in gum production, our Sesbania bispinosa seeds are specifically selected for high endosperm yield, ensuring maximum gum extraction efficiency. Each lot is tested for seed size uniformity and endosperm percentage.

Premium Livestock Forage with Exceptional Nutrition
Sesbania species, particularly S. sesban and S. grandiflora, rank among the highest-quality tropical forage legumes available. Their leaves contain 20-28% crude protein on a dry matter basis, which is comparable to or better than alfalfa (Medicago sativa), the gold standard of temperate forages. According to feeding trials published by ILRI (International Livestock Research Institute), cattle supplemented with sesbania leaf meal showed weight gain improvements of 25-40% compared to those fed only on grass pasture. The amino acid profile of sesbania forage is particularly noteworthy: it is rich in lysine, methionine, and tryptophan, the essential amino acids most commonly deficient in tropical grass-based diets. Sesbania also contains meaningful levels of calcium, phosphorus, and beta-carotene (a vitamin A precursor critical for reproductive health in livestock). For dairy operations, supplementing with sesbania has been shown to increase milk yield by 15-25% while improving milk fat percentage. In agroforestry systems, sesbania is planted as a hedgerow species and pruned regularly to provide continuous browse for goats, sheep, and cattle. The browse regrows rapidly — S. sesban can produce harvestable leaf biomass just 8-10 weeks after pruning, yielding 5-8 tonnes of dry leaf matter per hectare annually. This rapid regrowth makes sesbania an ideal protein bank for smallholder livestock operations in tropical and subtropical regions. Our sesbania seeds are selected from high-leaf-yield cultivars developed through participatory selection programs.

Reclaim Degraded and Saline Soils Naturally
Sesbania possesses remarkable tolerance to adverse soil conditions that would defeat most other crops. Sesbania sesban and S. rostrata can survive and thrive in soils with electrical conductivity up to 8-10 dS/m, waterlogging lasting several weeks, and pH levels ranging from 5.0 to 9.5. This makes them invaluable tools for reclaiming degraded agricultural lands — a growing global priority as climate change and poor irrigation practices continue to salinize millions of hectares of formerly productive farmland. According to the FAO Global Map of Salt-Affected Soils, over 833 million hectares worldwide are affected by salinity or sodicity, with the problem particularly acute in Pakistan, India, Central Asia, the Middle East, Australia, and the western United States. When sesbania is grown on salt-affected soils, its deep taproot system (reaching 1.5-3 meters) breaks through compacted layers and improves soil structure. The root channels left after decomposition enhance water infiltration and drainage, gradually leaching salts from the root zone. Meanwhile, the enormous biomass (15-25 tonnes of green matter per hectare) adds organic carbon that improves soil microbial activity and cation exchange capacity. Research by the Pakistan Agricultural Research Council (PARC) has demonstrated that three consecutive seasons of sesbania green manuring can reduce soil electrical conductivity by 30-45% and increase rice yields on formerly degraded land by up to 60%. For regions dealing with waterlogged soils, S. rostrata's unique stem-nodulating ability allows it to fix nitrogen even under flooded conditions, making it the ideal green manure for lowland rice systems.

Fast-Growing Reforestation and Carbon Sequestration
Climate-conscious buyers and environmental organizations increasingly choose sesbania for reforestation, afforestation, and carbon credit programs. Sesbania species are among the fastest-growing trees in the legume family: S. grandiflora can reach 8-10 meters in height within just 3-4 years from seed, while S. sesban achieves 3-5 meters in the same timeframe. This explosive growth rate translates to rapid canopy closure and carbon sequestration. Peer-reviewed studies published in Agroforestry Systems journal estimate that a sesbania agroforestry plantation can sequester 8-15 tonnes of CO2 equivalent per hectare annually during the first five years of establishment, making it an attractive option for carbon offset projects in tropical regions. Beyond carbon, sesbania provides critical ecosystem services: its flowers attract native pollinators (bees, butterflies, hummingbirds), its canopy provides habitat for beneficial insects and birds, its leaf litter feeds soil organisms that maintain soil health, and its root system prevents erosion on slopes and riverbanks. In coastal areas, sesbania has been used successfully for mangrove ecosystem restoration, where its salt tolerance and waterlogging resistance allow it to stabilize degraded shorelines while native mangrove species establish. Several UN-backed programs, including the Great Green Wall Initiative in Africa and the Billion Tree Tsunami in Pakistan, have incorporated sesbania into their planting prescriptions. Our seeds are sourced from provenances selected for rapid establishment, high survival rates, and genetic diversity — critical factors for long-term reforestation success.
