Abstract :

In order to study the effect of irrigation cycle and size of mother corms on flower yield and daughter corms in saffron, an experiment was conducted in Ghaen region in 2016 crop year using a split plot design. The main factor was irrigation cycles (2, 3 and 4 weeks) and the secondary factor was the size of corm (less than 4 g, 4 to 8 g, 8 to 12 and 12 to 16 g). The interaction effect of irrigation cycle and pistachio size on flower-related traits was insignificant and on female pistachio-related traits was significant. In mother corms less than 4 g and 4 to 8 g, irrigation cycle had no effect on the dry weight of daughter corms produced per square meter. Irrigation of mother corms 8 to 12 g and 12 to 18 g every two weeks, respectively, produced 3689 g and 4230 g of female corm per square meter, which increased by 7.5 and 9, respectively, compared to the four-week irrigation cycle. / 4% of this adjective. In mother corms less than 4 g, the two-week irrigation cycle increased the number of female corms per square by 7.5% compared to the four-week irrigation period and decreased the diameter of female corms by 9.5%, but in other sizes of mother corms There was no difference between irrigation cycles in terms of number of female corms per square meter and diameter of female corms.
