Saffron (Crocus sativus L.) is the most expensive spice in the world and the most valuable industrial medical product. In order to study the effects of corm density and planting method, an experiment was carried out as factorial based on randomized complete block design with three replications at the Agricultural Research Station, Ferdowsi University of Mashhad, during two growing seasons of 2009-2010 and 2010-2011. Treatments were two corm densities in 40 cm (5 and 10 corms) and two planting methods (row and mass). The results indicated that the simple effects of corm density and planting method were significant on all characteristics of saffron during two year of experiment. By increasing corm density from 5 to 10 corms per 40 cm, stigma yield was enhanced up to 12 and 10% for the first and the second years, respectively. In the first and the second years, mass planting method increased stigma yield 23 and 25% compared to row planting method for the first and the second years, respectively. Interaction effects between different treatments weren’t significant on any trait of saffron.
