Salinity is considered the most important abiotic stress for plants, because in addition to yield loss, reduces the amount of fresh water and land available for agriculture. The most important feature of them is the cation exchange capacity also has a high porosity zeolite-and nano-zeolites Ha for emission and entry and exit of fluids, especially water. improve plant growth occurs so study aimed to determine the impact of nano-zeolites and natural zeolites as part of substrates on basil (Ocimum basilicum) hydro cultivation was carried out under salt stress. Split split experiment with three factors: salt, zeolite and Reyhan (green and purple) was conducted in a completely randomized design. After planting seeds and plants, in the seventh week of salinity using sodium chloride (NaCl) at concentrations of 0, 30 and 60 Myly Mvlar with Hoagland solution was applied. Zeolite in levels of 0, 5, 10 and 15% by volume and nano-zeolites at different levels, 5.2 and 5% by volume with coco peat and perlite (volume ratio 1: 2) were mixed and used as part of Bstrksht was. Morphological traits including leaf area, leaf number, branch, fresh weight and dry weight of shoots and roots were measured. Measure chlorophyll content, total protein, peroxidase, proline and amounts of nitrogen, potassium, phosphorus, calcium, magnesium and sodium leaf was done. The results showed a decrease in all of the traits measured salinity and chlorophyll, protein, whole plant and nitrogen content, phosphorus, potassium, calcium and magnesium basil leaves and with increasing salinity, proline, peroxidase activity and sodium in shoot , Increased. The use of zeolites and zeolite nanoparticles in the medium reduce the adverse effect of salinity was also a significant difference between the zeolites and zeolite nanoparticles, so that the highest amount of vegetative traits (Andam Hvayy and root weight, number of lateral branches, leaf area, number leaves and height) are listed and the content of nitrogen,
