The genus Sesbania belongs to the Fabaceae (legume) family and encompasses over 60 species of herbs, shrubs, and small trees distributed across tropical and subtropical regions worldwide. For farmers, agronomists, and land-reclamation specialists, six species stand out as commercially and agronomically significant: S. bispinosa (Dhaincha), S. grandiflora (Agathi), S. rostrata, S. sesban, S. aculeata, and S. speciosa.
Each species occupies a distinct ecological niche. Some excel at rapid nitrogen fixation in flooded rice paddies; others produce edible flowers, high-protein fodder, or industrial gum. Selecting the wrong variety can mean poor establishment, wasted seed, and a missed growing season. This sesbania species comparison guide provides the data you need to make an informed decision — whether you are sourcing seed for a smallholder farm in Bangladesh, a gum-processing plant in India, or an agroforestry project in sub-Saharan Africa.
At Kohenoor International, we have been exporting premium sesbania seeds from Lahore, Pakistan since 1957. Our deep familiarity with these species — from field trials to post-harvest seed storage — underpins every recommendation below.

Dhaincha is the workhorse of the sesbania world and the species most commonly traded as seed. Native to the Indian subcontinent, S. bispinosa thrives in the waterlogged, saline, and alkaline soils that defeat most other green-manure crops. Farmers across India, Pakistan, and Bangladesh broadcast Dhaincha seed before the monsoon, then plough the 45–60-day-old crop into rice paddies to supply 80–150 kg of biologically fixed nitrogen per hectare. Beyond green manure, the seeds yield a valuable galactomannan gum used in the textile, paper, mining, and oil-drilling industries. The fibrous stems also serve as raw material for coarse rope, thatch, and handmade paper. If you need a single species that tolerates hostile soils and delivers rapid biomass, Dhaincha is the benchmark. Learn how to germinate sesbania seeds for optimal Dhaincha establishment.
Agathi is the tallest and longest-lived member of this group — a genuine tree reaching 8–12 meters within a few years. It is most valued in Southeast Asia, where its spectacular white or red flowers are eaten as vegetables, its protein-rich leaves (25–30% crude protein) feed livestock, and its fast-growing canopy provides shade in agroforestry systems. Unlike Dhaincha, grandiflora demands well-drained tropical soils and cannot tolerate prolonged waterlogging. In the sesbania bispinosa vs grandiflora debate, the choice hinges on purpose: bispinosa for annual green-manure rotations in wet fields, grandiflora for perennial food, fodder, and shade in upland orchards. Grandiflora flowers are a sought-after ingredient in Filipino, Thai, and Indonesian cuisine.
S. rostrata is unique among legumes for its ability to form nitrogen-fixing nodules on both roots and stems. This dual-nodulation system, driven by the bacterium Azorhizobium caulinodans, enables rostrata to fix an extraordinary 200–300 kg N/ha — far exceeding any other sesbania species. Originally from Senegal and the Sahel, rostrata has been widely studied as a biofertilizer for lowland rice. It matures quickly (60–90 days) and handles waterlogged, acidic soils with ease. Its limitation is modest drought tolerance, confining it to irrigated or high-rainfall environments. Researchers continue to explore rostrata as a model organism for stem nodulation genetics.
Originating in tropical Africa, S. sesban is a versatile short-lived perennial (3–8 m) used for green manure, fodder, firewood, and erosion control across East and Southern Africa. It tolerates a wider soil pH range than most sesbania species and shows good drought resistance, making it a reliable choice in semi-arid zones where rainfall is unpredictable. Protein content of the foliage runs 20–25%, and nitrogen fixation reaches 100–200 kg N/ha. Sesban is often planted as a fallow-improvement crop in maize-based systems — its deep roots break plough pans and recycle nutrients from lower soil horizons.
Closely related to S. bispinosa and sometimes treated as synonymous, S. aculeata is distinguished by the small prickles along its stems and slightly different pod morphology. It shares Dhaincha's affinity for heavy clay and waterlogged soils, and it is widely used in South Asia as a pre-rice green-manure crop. The stems produce a serviceable fiber for paper pulp and light cordage. While its nitrogen-fixation rate (70–120 kg N/ha) is somewhat lower than that of bispinosa, aculeata compensates with robust growth in heavy, poorly drained soils where other legumes struggle to survive. Understanding the distinction between aculeata and bispinosa matters for identifying sesbania as crop versus weed.
Native to the Americas, S. speciosa is the least commonly cultivated of the six species profiled here, yet it has niche value as an ornamental and a green-manure crop in warm-temperate to tropical zones. Its attractive yellow flowers and compact habit make it suitable for hedgerows and garden borders. Nitrogen fixation is modest (40–80 kg N/ha), and the plant does not tolerate flooding. Where speciosa shines is in well-drained, moderate-rainfall environments where a visually appealing nitrogen-fixing plant is desired — particularly in landscape restoration and roadside stabilization projects.
Choosing the optimal sesbania variety depends on your primary objective, soil conditions, and climate. Use the decision guide below to narrow your selection.
S. bispinosa (Dhaincha) is a fast-growing annual used primarily as green manure and for gum production, reaching 2–4 meters. S. grandiflora (Agathi) is a perennial tree growing 8–12 meters, prized for its large edible flowers, high-protein leaves, and agroforestry shade. Bispinosa excels in waterlogged and saline soils, while grandiflora requires well-drained tropical conditions. The choice depends on whether you need an annual soil-improvement crop or a long-term fodder and food tree.
S. rostrata leads with 200–300 kg N/ha, owing to its unique stem-nodulating capability. It forms nodules on both roots and stems via Azorhizobium caulinodans, giving it a dual fixation advantage that no other sesbania species can match. For farmers without access to rostrata seed, S. sesban (100–200 kg N/ha) and S. bispinosa (80–150 kg N/ha) remain strong performers.
S. bispinosa and S. rostrata both have excellent flood tolerance and are the go-to choices for rice-paddy green manuring. S. aculeata also handles moderate waterlogging. Avoid S. grandiflora and S. speciosa in flooded conditions — both suffer root rot and poor nodulation when soils remain saturated.
Yes. S. bispinosa demonstrates strong tolerance to soil salinity (up to 8–10 dS/m) and alkalinity (pH 8.5–9.5), making it a leading choice for reclaiming salt-affected land in coastal and arid regions. S. sesban and S. aculeata handle moderate salinity. Over successive cropping cycles, sesbania green manuring reduces soil salinity by improving drainage and adding organic matter.
S. grandiflora (Agathi) is the primary edible species. Its large white or red flowers are widely consumed as vegetables across the Philippines, Thailand, Indonesia, and India. The young leaves contain 25–30% crude protein and are used in salads, curries, and stir-fries. Young pods are also edible. While S. sesban leaves are sometimes fed to livestock, they are less commonly eaten by people.
