The effect of palm waste substrate on quality characteristics of 2 dwarf grenadines varieties and spray in soilless culture

 Growing plants in substrates are developing due to many advantages such as plant nutrient control, increasing product quality and quantity that soil cultivation and increasing performance. The purpose of this research is to investigating effect of particles size and period of compositing palm tree wastes as substrates on quality and quantity characteristics of grenadine this experiment was conducted in researches greenhouses of khorasgan Eslamic Azad university (Esfahan) as combine and then separated by sift in three sizes 0-0.5, 0.5-1 and 1-2 cm and 3 time periods 0 (without composting 3 and 6 month for composting period to be considered. Then these substrates with the cocopeat-perlit substrate were spilled in pots 3litrs and was planted grenadine with 2 different dwarf varieties and spray in to this bed. In dwarf variety, effect of substrate on flower diameter and canopy level was meaningful and in spray, none of the quality parameters were not meaningful difference.
