Introduction to Acacia modesta (Phulai)

Acacia modesta, commonly known as Phulai, is a member of the family Fabaceae (also called Leguminosae) and sub-family Mimosaceae. It is a deciduous, slow-growing small tree with thorny young shoots and dark brown and black wood. In natural forests, the trees have a 30-year felling cycle and 60-year rotation period on reaching 7 m height and 20 cm in diameter.

Distribution of Acacia modesta

This drought-tolerant tree is typically found in Pakistan, India, and Afghanistan, where it can grow in areas with yearly rainfall between 250 and 1300 mm.

Well adapted to semi-arid and sub-humid regions, Acacia modesta prefers temperatures ranging from -5°C to 40°C and exhibits some resistance to frost.

So far, no insect or disease problems have been identified, granting this tree great potential to be used in reforestation in dry and arid locations.

Importance of Acacia modesta

In terms of nutritional value, digestibility values range between 60% and 70%, depending on the type of soil and age of the plant. Typical values include 16.2% crude protein, 22.8% crude fiber, 8.1% ash, 2.1% ether extract, and 50.7% nitrogen-free extract.

  • In drylands, Acacia modesta is an important forage species.
  • Tender leaves and twigs, in particular, have a high nutritional value and palatability and are used as fodder for goats and camels.
  • With around 16% protein levels, young shoots are typically used to supplement grass during the dry season.
  • For livestock, this mixture is ideal to improve nutrient utilization and increase weight gain.
  • The plant is also popular in herbal medicines, including those for the treatment of muscular conditions, back pain, and stomach problems.
  • Other uses include fuel, wood, apiculture, gum, and soil conservation.



Establishment and Management

Acacia modesta can be propagated through seed. Clean seed must be stored in a cool dry place, ideally in airtight containers to avoid excessive losses in germination rates. It can safely be kept in these conditions for up to three years.

Fresh seeds can be sown as they are, but if using older seeds a pre-treatment to facilitate germination is recommended. This may involve nicking the seeds to remove the outer coat and/or soaking in water for 24 hours or sulfuric acid for 5 to 15 minutes. Treated seeds should be planted immediately.

For planting, the best method is to sow seeds in nursery conditions in polythene tubes containing a 2:1 silt and manure mixture. Seeds start to germinate within 1 to 2 weeks, but should only be transplanted to the field after 9 to 12 months. Very young plants need to be protected from grazing.

The same tree can be harvested multiple times taking advantage of its ability to re-grow new shoots from buds left in the stumps of felled trees. This traditional silvicultural methodcoppice system – is very common in extensive drylands.
