Pot mixes are the most important factors for the production of quality flowers in floriculture. Nowadays, it is becoming the first preference of farmers because flowering crops offer higher yields than traditional crops and its commercialization offers small and large producers a way to increase the level of sustainability of their farms. Globally, more than 140 countries are involved in floriculture cultivation (Anonymous, 2006). In recent years, farmers and nurseries are very concerned about potting media because they play an important role in crop production. There is a continuing interest in the use of various agricultural by-products as a source of organic nutrients for plants due to the increasing awareness of environmental issues, as well as the need to eliminate and use increasing quantities of waste (Grigatti, 2008). materials from agriculture, forestry, green spaces and livestock as well as municipal and industrial waste residues are strongly recommended to be used as renewable resources in the production of pots, thus compensating their harmful impact and negative on the degradation of the local and global environment. Peat is the most widely used substrate for the production of potted plants in nurseries and represents a significant portion of the materials used to grow potted plants (Marfa et al., 2002; Ribeiro et al., 2007). Waste is a potential substitute. for peat for sustainable horticultural production. The dahlia is a beautiful, important flower that belongs to the compositae family and is native to Mexico. It has attracted the attention of many people all over the world due to the extraordinary quality of its flowers and its variations in color and size. It currently has 35 renowned species and around 20,000 cultivars......middle of paper......different compositions. If such media are evaluated for better growth, development and flower production, they can be marketed in nurseries. The first objective of this research was to evaluate different potting mixes for the growth and flowering of Dahlia x 'Figaro Amélioré'. This project was subjected to the exploration of different types of media like silt, coconut fiber, dust, sludge, spent mushroom compost, rice husk alone and in different compositions for dahlia production. Along with the study of dahlia growth and flowering, the chemical properties of the media such as nutrient availability, electrical conductivity (EC), and pH were also evaluated. The main objective was to develop an effective protocol for the mass propagation of dahlia cultivars in the most appropriate environments in order to improve quality production for nurseries and local markets...
