In order to study the effect of planting density on flower and corm yield of Spanish and Iranian saffron (Crocus sativus L.) types, an experiment was arranged in factorial with randomized complete block design with three replications. This experiment was conducted on the Research Farm of the Faculty of Agriculture, Ferdowsi University of Mashhad in 2013-15. The saffron corm type was considered in two levels (a1: Iranian corm and a2: Spanish corm) and the planting densities were in three levels (d1:40, d2:48 and d3:60 corm.m-2). The two year results showed that the effect of different planting density and saffron corm types on the number of flowers, flower fresh and dry weight (stigma + style) and number of replacement corms were significant (P<0.01) while, the effect of corm type on fresh and dry weight of replacement corms was not significant. The highest number of flowers (30.25 No.m-2), flower fresh weight (15.125 g. m-2) and (stigma + style) dry weight (0.16 g.m-2) were obtained in d2 (48 corm.m-2), respectively. Corm type had significant effects on saffron flower characteristics. The highest numbers of flowers (27.21 No.m-2), flower fresh weight (13.58 g.m-2) and (stigma + style) dry weight (0.144 g.m-2) were obtained from Iranian corms (a1), respectively. However, the highest number (222.83 No.m-2), fresh weight (694.92 g.m-2) and dry weight (270.32 g.m-2) of replacement corms were obtained from Spanish corms (a2), respectively. The years had significant effects on saffron flower and corm characteristics as the highest amounts were obtained in second year (Y2), respectively.

Saffron flowering can be mainly affected by mother corm size and phosphorus content of corm. In order to investigate the effects of mother corms size, organic fertilizers and foliar application on corm yield and phosphorus uptake of saffron (Crocus sativus L.) under control conditions, an experiment was conducted in the growing years of 2012-2013 at Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, by using a complete randomized design with 24 treatments and three replications. The mother corms size (0.1-4 g (small), 4.1 – 8 g (medium) and 8-12 g (large), organic fertilizers (cow manure 25 t. ha-1, vermicompost 10 t. ha-1,compost 10 t. ha-1 and control) and micro nutrient (Fe-EDTA and Zn-EDTA) in two levels (foliar application and no application) were the first, second and third experimental factors, respectively. Based on the results, the highest number and yield of replacement corms were observed by using the large (8.1-12g) mother corms. The effect of cow manure on replacement corm yield was significantly more than other organic fertilizers. The effect of foliar application on replacement corms yield were also significant. In addition, the highest concentration and content of phosphorus replacement corms was observed by using the large (8.1- 12g) mother corms. The content of phosphorus in replacement corms was significantly decreased by reducing the size of the mother corms.
