In general, corm weight and nutrient management are considered as the most important factors in relation to quantitative and qualitative traits of saffron. In order to investigate the effects of mother corm origin, mother corm weight and nutrient foliar application on yield and qualitative traits of saffron, a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at the Faculty of Agriculture, Ferdowsi University of Mashhad, Iran, during the years from 2012 to 2015. The mother corm origin (Iranian and Spanish corms), mother corm weight 8 g and lower (small), 8.1–15 g (medium) and 15.1-23 g (large) and nutrient foliar application (application and control) were considered as the first, second and third experimental factors, respectively. According to the results, the larger mother corms significantly resulted in a greater number of flowers per m2, increased fresh flower and dry stigma + style yields. However, the effect of nutrient foliar application was observed to be not significant on these traits. When Iranian mother corms were planted, the number of flowers per m2, fresh flower and dry stigma + style yields were higher, compared with Spanish mother corms. For instance, flower number, fresh flower and dry stigma + style yields increased by 17, 13 and 14%, respectively, when planting Iranian mother corms. Nonetheless, picrocrocin concentration was higher (up to 3.8%) in the Spanish planted corm treatment. Based on the results, beside the optimal nutrient foliar application, the importance of adapting the corms origin with environmental conditions of the site designated for planting is emphasized.

The corm size, nutrient management and corm type are the most important factors that may affect the quantitative and qualitative characteristics of saffron (Crocus sativus L.). In order to study the effect of mother corm size and nutrient foliar application on flower and corm yield of Spanish and Iranian Saffron landrace, an experiment was conducted with factorial arrangement based on randomized complete block design with three replications during two growing seasons (2013-14 and 2014-15) at the Faculty of Agriculture of the Ferdowsi University of Mashhad, Iran .The saffron corm type was considered in two levels (Iranian corm and Spanish corm), mother corm size were in three levels (1- 8g, 8.1- 15g, 15.1- 23g) and nutrient foliar application were in two levels (control and sprayed leaves with 7% micro and macro nutrients). The results showed that the effect of different mother corm size, corm type and nutrient foliar application on the number of flowers, flower fresh and dry weight (stigma + style) were significant. The highest number of flowers (48.6 flower.m-2), flower fresh weight (24.3 g.m-2) and saffron (stigma + style) dry weight (0.25 g.m-2) were obtained in 15.1-23g mother corm size, and the lowest were obtained in 8g > mother corms. In contrast, nutrient foliar application had not significant effect on total produced daughter corms. However, the highest number of flowers (43.7 flower.m-2), flower fresh weight (21.8 g.m-2) and stigmas dry weight (0.23 g.m-2) were obtained from Iranian corms in the second year. Hence, the use of appropriate weight for planting Iranian corms (over 15 g) with nutrient of foliar application can be useful for increasing the performance of the flowers and saffron corms.
