Behavior Of Acacia Plants Installed On Substrates Based On Compost Sylvicole With Or Without Methacompost Of Poultry In A Modern Nursery In Tunisia



Auteurs : M’sadak Y. . Ben M’barek A. . Tayachi L. .

Résumé

The present study aims principally the evaluation of germination and of plant growth of Acacia cyanophylla installed, on the one hand, on the gross forestry compost (CSB) in its purest form, produced in a forest nursery in Tunisia, on the other hand, on the CSB mixed with poultry methacompost (MCA) refined (solid residue from the industrial digester) in its two states, namely the output of the decanter (MCAA) and the outlet of the digester (MCAA') according to the same ratio, of 20 %. Both tested mixtures were the best, due to the direct assessment of physico-chemical properties of various mixtures made. The incorporation of the MCA with the CSB has a notable positive effect on germination, and consequently on the growth of Acacia seedlings in terms of height and diameter. The CSB presented an intermediary vegetative behavior.

Mots clés
