Optimization test of the domestication of five Saharan Acacia: Effect of substrate and container on the growth Acacia gummifera, Acacia tortilis, Acacia nilotica, Acacia albida and Acacia seyal in the nursery Tests of growth of five species of Acacia have been conducted in various substrates in three types of rigid racks of different volumes in the nursery.

To have high rates of germination, the seeds of the species studied have incurred different pretreatments.

The growth monitoring for a period of six months showed that the effect of the rate of the organic material in the substrate is greater than the effect of the volume of the rigid container in all Acacia species.

A positive correlation between the organic matter content of the substrate and the improving plant growth was logged in five species of Sahara Acacia.

Acacia nilotica and Acacia tortilis showed higher biomass production, followed by Acacia gummifera and Acacia seyal and finally Acacia albida
