Description: SESBANIA SESBAN 1,000 seeds Sesbania sesban is a many-branched, soft-wooded tree that grows rapidly and is useful for fodder and green manure. This species has long been used for browse and soil improvement in India and Africa. Recent interest in multipurpose, nitrogen fixing trees has caused it to be collected, studied, and recommended for fodder “banks” and alley cropping. BotanySesbania sesban (L.) Merrill is a tree that grows to 8 m height. This papilionaceous (pea-like flowered) legume bears racemes of 4-20 yellow flowers that may be lightly to heavily streaked with purple. Sesbans have pinnate leaves with 20-50 opposite pinnules on a rachis 3-12 cm long. The leaf rachis and the underside of the leaflets are often pubescent. The pods are usually 10-20 cm long and contain up to 40 seeds that are brown, or dark green mottled with black. The trees usually have one main stem, but they may develop many side branches if they have space. Sesban’s many branches often give the tree a shrubby appearance. It tends to have a spreading habit due to its wide branching angle (as wide as 45-60° ). Rapid establishment and early growth High nutritive quality for ruminants Acid-soil, waterlogging and salinity tolerances Native to or naturalized in Africa, Asia and Australia Grows in a wide range of soils from loose sands to heavy clays Long history of use in India, primarily as a green manuring and a source of cut-and-carry forage. Can be intercropped with corns, beans, cotton and other field crops. Leaves are a good source of protein for cattle and sheep. Used as a grazed forage in sub-tropical Australia and Kenya . Used as a reclamation species of saline soils in Southern China. Produces a light fuel wood suitable for cooking and charcoal production. Used as a live support for black pepper, grapes, cucurbits and betel vine and as a shade tree for coffee and turmeric.Tolerates saline soils (1.0% salt concentration in the seeding stage to 1.4% at maturity), alkaline soils (pH<10), and acidic soils, as well as waterlogging and flooding. Tolerant of low P, but P application has a positive effect on growth and nodulation. . Tolerant of metalliferous mine tailing high in Cu,Zn and Pb. Moisture: Native to monsoonal, semi-arid to sub-humid regions with 500-2,000mm annual rainfall. Grows best where periodic waterlogging or flooding is followed by a progressive drier season.Tolerant of cool highland-tropical or sub-tropical conditions, growing at up to 2,300 m altitude in Kenya and as far as south as 27° latitude in Australia. Average annual temperatures ranging from 17-20°C. Tolerates light frosts, but will be killed by heavy frost. Has moderate shade tolerance. Flowering is prolific and will occur within 12 months of sowing. It is photoperiod sensitive, flowering into short days(peak flowering occurs in April-May in Queensland, Australia).Seeds matures in 2-3 months. Dormancy in seeds of Sesbania sesban is caused by a water-impermeable seed coat (hard seeds or hardseededness). A two-phase pretreatment technique was developed for breaking seed dormancy and was validated using different accessions and seed lots. Seeds were first soaked in water at 80 °C for 8 min and prepared for the germination test. Ungerminated hard seeds at the first count (after four days incubation) during the germination test were then subjected to a second treatment by mechanically scarifying the seed coat. The effects of water temperature and variation in initial hardseededness and viability among and within accessions were also investigated. The optimum water temperature, allowing maximum seed germination without increasing the percentage of abnormal seedling/dead seeds was 80 °C. The mean percentage of hard seeds across 30 seed lots of six accessions was reduced to 26% after phase 1 and to 0% after phase 2. In addition, full germination occurred within only 10 days for treated seeds while germination in untreated seeds had reached only 48% after 14 days. Significant differences existed among the seed lots within the accessions (p > 0.05) for the percentage of initial hard seed and for the effects of treatments on breaking seed dormancy. The two-phase technique developed was validated using over 1000 seed lots of S. sesban, and it was found to be a rapid and cost-effective method for breaking hard seed dormancy with potential for wider use for hard-seeded legumes.
