Tamarind which is scientifically known as Tamarindus indica is a leguminous tree that belongs to the family Fabaceae. This is fundamentally a tree of tropical climate regions that can flourish best under a maximum annual temperature ranging from 33-37°C to a minimum of 9.5-20°C1.

Seed germination is considered a vital and susceptible stage in the life cycle of terrestrial angiosperms which determines the seedling establishment as well as plant growth2. However, in some cases, seeds are unable to germinate though they have a favorable condition, known as dormancy3. This phenomenon hinders efficient nursery management and plantation establishment4. For this reason, dormant seeds should be pre-treated to break dormancy and achieve effectual germination.

Tamarind is regarded as a multipurpose tree with versatile uses. It is considered as a component of agroforestry as it possesses nitrogen-fixing ability. Moreover, it can also tolerate infertile soil as well as erosion5. Also, the heartwood of this tree is very resilient and employed in furniture making6. Furthermore, its medical value can't be denied as well. Accordingly, its fruit is utilized to treat intestinal diseases, fever, and malarial fever as well as scurvy7. Tamarind pulp is also a well known and effective medicine for paralyzed people to restore sensation and to treat painful and wounded throats8.

Accordingly, a new experiment was designed for assessing the effects of different treatments on seed germination and seedling growth performance of T. indica in the nursery9.

In this research, seven treatments were involved, including control, socking seed in hot water treatment 100°C for 5 and 10 min, soaking seeds in cold water for 48 h, soaking seeds in farmyard manure for 48 h, soaking seeds in concentrated H2SO4 for 3 min as well as cracking of seeds9.

At the end of this experiment, scientists recommended socking with farmyard manure for 48 hours in addition to conc. H2SO4 for three minutes as this treatment was found to possess the ability to stimulate the germination percentage, biomass production, seedling growth, seedling quality indices in comparison with other treatments. Hence, acid treatment may be recommended for maximum seed germination and quality seedling production programs.

Conclusively, considering the risk of employing conc. H2SO4, seeds soaked in farmyard manure for 48 h are the superior alternative for seed germination as farmyard manure is pocket-friendly, easy to apply and possesses no damaging effect on the human body.
