The trunk is underground. The fruits, which occur in clusters at the base of the palm, are characterized by its reddish-brown scaly skin. It can be eaten raw when fully ripe or made into candies. Unripe fruits, on the other hand, are used in salads. Among the about 30 cultivars of this plant, there are two popular cultivars named as salad poncho and salad Bali. There are no reported medicinal uses of Salak Palm. The leaflets are used for thatching and the bark of the petioles are used for matting.

Edible Uses
Edible Parts: Fruit Seed
Edible Uses:
Fruit - raw[297 ]. An acid flavour[297 ]. Slightly crisp, with a delicious blend of acids and sugars and an apple-like flavour[200 , 301 ] The flesh is exceptionally firm and crisp for a tropical fruit[303 ]. It is quite sweet when fully ripe, but the unripe fruit is sour and astringent due to the presence of a little tannic acid[303 ]. Considered to be one of the finest of palm fruits for eating raw[301 ]. In Indonesia the fruits are also candied ('manisan salak'), pickled ('asinan salak') and fresh unripe ones may be used in 'rujak', a spicy salad of unripe fruit[303 ]. The reddish-brown, ovoid fruit is 6 - 8cm in diameter[200 ]. The seed is edible[301 ]. The seed kernels of the young fruits of the Javanese 'Pondoh' form are edible[303 ].

Cultivation details
A plant of the humid, lowland tropics, where it is found at elevations up to 500 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 30°c, but can tolerate 12 - 36°c[418 ]. It prefers a mean annual rainfall in the range 1,700 - 3,100mm, but tolerates 1,400 - 3,500mm[418 ]. Requires a deep, rich, moist soil and some shade[303 ]. Prefers a light-textured soil[418 ]. Young palms require heavy shade which may be reduced after about one year[303 ]. Because of its superficial root system, the palm requires a high water table, rain or irrigation during most of the year, but it does not stand flooding[303 ]. Prefers a pH in the range 5 - 6, tolerating 4.5 - 6.5[418 ]. The palm starts flowering three to four years after sowing[303 ]. It can be productive for 50 years or more[303 ]. The scarce data available suggest that annual yields vary from 5 - 15 t/ha[303 ]. There are some named varieties[301 ]. A dioecious plant, requiring both male and female forms to be grown near each other if fruit and seed are required[200 ]. One male plant is usually adequate to fertilise nine females[200 ]. There is at least one monoecious variety[303 ]. 'Bali' produces inflorescences with both hermaphrodite and staminate flowers; the latter produce functional pollen[303 ]. Spacing: 10-12 ft. (3-3.6 m) 12-15 ft. (3.6-4.7 m) 15-20 ft. (4.7-6 m) 20-30 ft. (6-9 m).

Plant Propagation
Seed - pre-soak for 24 hours in warm water and sow in containers[297 ]. The seed needs to be fresh, it takes 2 - 3 months to germinate[297 ]. The seeds are sown directly in the field (2-5 seeds together in 5 cm deep holes) or in nursery beds. The seedlings are planted out in the field during the rainy season when they are a few months old[303 ]. Germination becomes visible when the cylindrical embryo-containing plug is extruded through the germpore at the kernel's apex. A radicle soon emerges from the tip of the plug and the shoot, a main root and several secondary roots emerge from the sides of this plug. About 60-90 days after sowing the first complete leaf, bifid and some 20-30 cm long, is fully expanded, the seedling still being firmly attached to the kernel[303 ]. Division of suckers[335 ].
