“…In the literature, there are a lot of studies about the gladiolus: corm size (Laskar and Jana, 1994;Kazaz and Özzambak, 2002;Memon et al, 2009), plant growth regulators (Karagüzel et al, 1995), planting time (Kalasareddi et al, 1997;Özzambak and Kazaz, 2002;Ahmad et al, 2011), adaptation (Gürcan and Türkoğlu, 2000), irrigation (Baştuğ et al, 2006), plant nutrition (Halder et al, 2007), low temperature applications (Zalewska and Antkowiak, 2009), planting time and phenology (Schwab et al, 2015), heritability (Patra and Mohanty, 2015), planting spacing and depth (Tomiozzo et al, 2018), and hybridization (Hossain et al, 2012;Azimi, 2019) on yield, quality and earliness in gladiolus have been investigated by many researchers. However, the studies conducted on gladiolus in soilless culture are limited (Bazaraa et al, 2014;Saeed, 2018).…”
