Saffron (Crocus sativus L.) is one of the highest-priced spices in the world (Winterhalter and Straubinger, 2000). It is grown for its red scarlet stigmas that are used as spice and natural dye. KSA is considered as one of the largest Saffron imported country, in 2020, KSA imported 125 tons of dry saffron stigma (General authority for statistics,2020). Saffron flower induction, growth and new corms formation affected by environmental conditions (Kafi et al., 2002), plant density (El Hajj, et al., 2019) and planting depth (Skinner et al., 2017). The aim of this study was to evaluate the effect of corms plant density and planting depth on flowering induction, stigmas yield, and plant growth under greenhouse conditions in KSA.
