In recent decades, the production of greenhouse products has relied on the consumption of chemical inputs, which has led to biological and environmental problems. For this reason, replacing fertilizers based on nano formulations has been considered. This experiment was conducted in order to investigate the comparison of conventional and nano chemical fertilizers on the cultivation of cut roses under soilless cultivation conditions in the form of a randomized complete block design in two cultivars (Samurai and Avalanche) at one level of common chemical fertilizers and five different levels of fertilizers based on Nano technology includes 30% elements of common chemical formulation, 15% elements of common chemical formulation, commercial formulation of Sodour Ahrar Shargh (SAS) company, 50% of commercial formulation of SAS company and 50% of commercial formulation of SAS company with irrigation fertilizer three days a week including three repetitions and each repetition includes nine plants of every digit was done. During the experiment, the traits of stem length and flowering diameter, bud diameter and length, flower tail length, flowering stem weight, leaf length and surface area, flowering stem fresh and dry weight, bud fresh and dry weight, chlorophyll, carotenoid, anthocyanin, total carbohydrate and content Leaf elements were investigated. Based on the results of this thesis, in terms of quality characteristics, life after harvest and the number of flowers, the Avalanche cultivar has performed better than the Samurai cultivar. The post-harvest life in all treatments fed with nanotechnology-based fertilizers was higher than the post-harvest life in flower branches fed with common chemical fertilizers. The lowest level of chlorophyll and carotenoid was observed in the regim with the formulation proposed by SAS company. There was no significant difference between the values obtained from the eva‎luation of the nutrient solution of common fertilizers and the nutrient solutions of nanochelate fertilizers regarding traits such as bud diameter, bud length, bud fresh and dry weight, stem weight and length, stem diameter and leaf area. According to the results obtained from the plants fed with 50% commercial formulation of SAS with irrigation fertilizer three days a week and comparing with the yield of flowers obtained from plants fed with common chemical fertilizers and 50% commercial formulation of SAS with irrigation fertilizer on a daily basis, the possibility of reducing fertilizer consumption through There is a reduction in fertilization days.
