Soil mixes are the most important factors for the production of quality flowers in floriculture. Nowadays it becomes the first preference of farmers because flowering crops provide higher yields than traditional crops and its commercialization offers both small-scale and large-scale growers a way to increase the level of sustainability of their farms. Globally, more than 140 countries are involved in the cultivation of flower plants (Anonymous, 2006). In recent years, farmers and nurserymen are very concerned about potting media as they play an important role in plant production. There is ongoing interest in using various agricultural by-products as a source of organic nutrients for plants due to growing awareness of environmental issues as well as the need to dispose and use increasing amounts of waste (Grigatti, 2008). Materials from agriculture, forestry, green areas and livestock, as well as residues from municipal and industrial waste, are strongly recommended for use as renewable resources in the production of pots which mitigate their harmful and negative impact on the local and global environmental degradation. Peat is the most used substrate for the production of potted plants in nurseries and represents a significant part of the materials used to grow potted plants (Marfa et al., 2002; Ribeiro et al., 2007). Waste materials are the potential substitute for peat for sustainable horticultural production. The dahlia is a beautiful, important flower that belongs to the composite family and originates from Mexico. It has attracted the attention of many people around the world due to the extraordinary quality of the flowers and the variation in color and size. It currently has 35 renowned species and around 20,000 cultivars......half of the paper......different compositions. If such substrates are evaluated for better growth, development and production of quality flowers, then they cannot be marketed in the nursery sector. The first objective of this research was to evaluate different potting mixes for the growth and flowering of Dahlia x 'Figaro Improved'. This project was subjected to explore different types of materials such as silt, coir, dust, sludge, spent mushroom compost, rice husk alone and in different compositions for dahlia production. In addition to studying dahlia growth and flowering, chemical properties of the media such as nutrient availability, electrical conductivity (EC) and pH were also evaluated. The main objective was to develop an efficient protocol for mass propagation of dahlia cultivars in the most suitable soils to improve quality production for nurseries and local markets..
