In recent years many research studies have been carried out to use a vertical planting system for production of some plants. Although saffron is one of the most expensive spices in the word, there is no investigation about saffron production in a vertical planting system. Therefore, the growth and production of saffron plant in two different systems (vertical and horizontal) were studied in the agricultural research field of the Tarbiat Modares University during the 2013-2014 growing seasons. In the vertical system, saffron corms were planted in fabric bags containing potting soil. The fabric bags were hanged on a cube of metal with an area of each side of the cube being equal to 2.25 square meters. In the horizontal system, the corms were planted in three plots with the area of each plots being 2.25 square meters. The results showed that in the vertical planting system, the number of flowers, flower dry weight and dry weight of stigma per unit area of land (10 flower, 347.34 and 0.56 mg respectively) were significantly higher than those obtained in the horizontal culture (They were almost three times higher) .In contrast, the numbers and dry weight of lateral corms (2.4 corm and 0.36 g respectively) and the dry weight of apical corm (0.88 g) in the horizontal system were significantly greater than those obtained in the vertical system. Dry weight of leaf and root were significantly greater in the vertical system. The total number of buds and leaves were more in the horizontal culture. However, the maximum leaf length of the vertical planting system was higher than those of the horizontal system.
