Salinity is an important factor limiting vegetative and reproductive growth of most crops. Strawberry plants are sensitive to salt stress and the factors influencing the growth and performance, water quality and soil is required. If the concentration of sodium chloride increased the yield is reduced drastically. One of biological solutions to improve the plants grow in salty environments, the use of mycorrhizal fungi. Under salt stress, mycorrhiza minerals needed by plants, especially phosphorus improves. Phosphorus can also increase salinity tolerance, growth and yield of crop. Therefore, this study examined the effects of mycorrhiza and phosphorus on growth and yield of strawberry under salt stress was conducted. A factorial experiment with three mycorrhiza, phosphorus and salt in a completely randomized design. In this study camarosa strawberry varieties were used. Strawberry seedlings for mycorrhizal fungi Glumus mossea and Glumus intraradices for a month in cocopeat and perlite were planted. In control of mycorrhiza autoclave was used. After the salt treatment at three levels of 1.5, 3 and 4.5 dS/m , was applied from the source sodium chloride and phosphorus treatment at three levels, 40 and 80 mg /kg of source triple super phosphate fertilizer. Vegetative characteristics including levels of total and single leaves, leaf number, chlorophyll, fresh weight of shoot and root dry weight percentage of shoots and roots, reproductive traits such as number of flowers and fruits, length, diameter and volume of fruit, fruit weight and yield per plant traits a briefcase containing soluble solids, anthocyanin, acidity, ascorbic acid, proline and peroxidase elements nitrogen, phosphorus, potassium, magnesium, calcium and sodium were measured. The results showed that the concentration of sodium chloride in the medium, measured traits except Anthocyanins, acidity, proline, peroxides and sodium decreased. Mycorrhiza and phosphorus treatment significantly reduced the negative e
