Evaluation of mud-based culture substrate on the regeneration of verbena cuttings

The aim of this study was to assess the quality of sludge by a physico-chemical approach and see the effects of its use in improving the culture substrate for increasing the productivity of verbena cultivation. , and find a solution to the sludge from treatment plants by replacing chemical fertilizers. Materials and Methods: It was carried out at the level of the botanical garden of the University of August 20, 1955, in Skikda (Algeria), the botanical garden with a surface of one hectare, with collections of ornamental trees and exotic plants. The test was placed in a greenhouse under uniform conditions to ensure that all containers are placed under the same conditions. Results: Analysis of variance revealed that all significant differences in morphological point were not due to the block factor but only to different substrates. The results allow us to affirm that the culture substrate-based sludge can be recovered, their characteristics acquire their potential for use. From the morphological point of view, the supply of sludge used as a culture substrate was beneficial for improving plant growth verbena except for the substrate S4, 90% of sludge, which had opposite effects compared to other substrates. Conclusion: It was concluded that the latter is very rich in organic matter, with a value of 55.67%, according to the AFNOR standard, a value of 40 to 65% seems very good for a recovery of this mud as a growing medium.
