The effect of organic growning media on growth of Spathiphyllum spp

In this research studied effect of palm peat and leaf manure as a replacement of peat moss in production of Spathiphyllum spp. in the form of factorial experiment in the base of completely randomized design with 6 treatmants and 4 replications. Growth indexes and also physical and chemical properties were evaluated. Results showed that media containing 35% peat moss 35% palm peat 30% perlite, 35% peat moss 35% leaf manure 30% perlite and also 35% palm peat 35% leaf manure 30% perlite had highest effect on growth of plant. According to the results, because of easy of availability and lowercost of palm peat than the peat moss, usage of this material in combination with peat moss or leaf manure can be substitute instead of imported media containing 50% peat moss 50% perlite in growth Spathiphyllum plant and other foliage plant in Iran.
