In order to investigate the effect of soil texture and density on corm and flower yield of Saffron an experiment was conducted as a factorial based on complete randomized block design with three replications at Faculty of Agriculture, Ferdowsi University of Mashhad in the growing seasons of 2009-2010 and 2010-2011. Treatment included 6 soil texture (clay loam, silty loam, loam, sandy loam, loamy sand and silt) with 2 plant density (100 and 150 corms per m2). Results indicated that corm number and dry weight was affected by soil texture, significantly. The highest number and dry weight of corms was observed in loamy sand texture. Loamy sand, sandy loam and silty texture had the maximum flower number. The highest stigma yield was obtained in silty texture (1.22 g.m-2)but with no significant difference with sandy loam. The lowest stigma yield was in clay loam, loam and silty loam textures. A negative significant correlation was observed between clay percentage of soil and corm number and dry weight, flower number and flower and stigma yield. In two growing seasons, plant density didn’t have significant effect on flower number and flower and stigma dry weight.
