This research was conducted to evaluate the possibility using peanut shelles compost as appropriate medium in the cultivation of ornamental plants by a completely randomized design in three repetitions in ornamental plants and flowers research station, Lahijan, Iran. A 2:1 ratio of peat to perlite and peat was used as control treatment and peat was replaced by 15, 30, 45, 60 and 100 % v/v of peanut shelles compost in two methods: 1. treatments with nutritional solution and 2. treatments without nutritional solution. Growth indexes include height, crown diameter, fresh and dry weights of leaf were measured in dracaena plant. Nutrients concentration of nitrogen, phosphorus, potassium and calcium in the dracaena leaf were also measured. Results showed that nutritional solution had a considerable effect on plant growth in all treatments than without nutritional solution. Peanut shelles compost had more affects on growth properties like height and dry weight of leaf in compared to control. The lowest growth was related to 100% treatment of peanut shelles and control. In result, peanut shelles compost increases the growth of plant but their effect on plant growth is promoted when accompanied with nutritional solution.
