Evaluation the effect of physical and chemical properties of some organic and inorganic substrates in growth of Dracaena fragrans 'Lemon Lime

For evaluation possibility of substituting peat moss media with new media creating with different organic wastes and mineral materials، this research work was conducted. Since using suitable media one of the important task in production of potted plants، different rate of peat moss، municipal waste compost and palm peat in combination with perlite and zeolite used as treatments in this project. Physical and chemical properties of media different growth indexes of plant were evaluated. Thus best plant growth indexes observed in treatments containing 50% peat moss+ 50% zeolite; 25% palm peat + 25% municipal waste compost + 25% perlite + 25% zeolite and 50% peat moss+ 25% perlite + 25% zeolite. Because of ease of availability and lowest cost of municipal waste compost، palm peat and zeolite these media could be used as commercial media instead of 50% peat moss + 50% perlite. Also according to the results، it is possible that used zeolite as mineral element replacing of perlite، in combination with peat moss or other organic materials or even as individual media in production of Dracaena fragrans 'Lemon Lime' or other potted ornamental plants in Iran.
