Narrated Jubair bin Mutim: That while he was with Allah’s Apostle who was accompanied by the people on their way back from Hunain, the bedouins started begging things of Allah’s Apostle so much so that they forced him to go under a Samura tree where his loose outer garment was snatched away. On that, Allah’s Apostle stood up and said to them, “Return my garment to me. If I had as many camels as these trees, I would have distributed them amongst you; and you will not find me a miser or a liar or a coward. Sahih Al-Bukhari, book of fighting for the cause of Allah.

Growth and propagation

Tree management

• Germination: Seed may be sown directly on site in mulched lines 5 m apart, or in patches (Parkash 1991). Seeds are often extracted by pounding pods in a mortar followed by winnowing and cleaning. The hard-coated seeds remain viable for several years under cool, dry conditions. They require pretreatment for good germination. Mechanical scarification works best for small seed lots. Soaking seeds either in sulfuric acid for 20-30 minutes, or in poured, boiled water allowed to cool, are both effective treatments (Fagg and Greaves 1990). • Transplanting: It is better to plant nursery-raised seedlings in containers in areas of erratic rainfall (Parkash 1991). For containerized seedlings, sow 2 seeds per pot. Young seedlings are sensitive to hot winds. • Pruning • Supporting

Harvesting & Yield

• Harvesting • Yield A. tortilis is a good shade tree for people and for silvipastoral agroforestry uses in arid areas. It is not good for intercropping or near farmland due to wide, shallow roots (Teel 1984). Useful for sand dune stabilization, shelterbelts along canals and roads, and in sandy arid areas. It is recommended for semiarid areas on sandy soils with low rainfall, for fuelwood production (Forest Division 1984). Multiple products can be obtained from this tree e.g. fuel wood, charcoal, timber, poles, fodder, medicinal, tannin, molluscicide and algicide.
