Different substrates have several materials which could have direct and/or indirect effects on plant growth anddevelopment. Therefore selecting the best substrate between the various materials is imperative to plantproductivity. This research was carried out with using a completely randomized design with three treatments andseven replications. The treatments were including perlite, date-palm waste and soil. During plant growth irrigationrate, temperature, humidity, pest control for all treatments were similar. Cucumis Stativus cultivar was used for seeds.During plant growth Papadopolus formula with fertigation method used for nutrient solution. Somephysiochemical characteristics of cultivation substrates were measured. The growth indices of cucumber plant weremeasured at the end of growth period. Results showed that higher amount of yield, biomass weight, SD, plantheight, root weight, LAI and fruit TSS related to date-palm waste that had a significant difference with soil at 5%level but generally had not any significant difference at 5% level as compared with perlite substrate.
