In order to increase the quality and yield of saffron, an experiment was conducted in the Alborz province, (Eshtehard), in the year 2016-2017 through the interaction of nitroxin biological fertilizer and irrigation management. The experiment was conducted as split plot in randomized complete block design with 3 replications. The experimental factors included irrigation method (Surface drip Irrigation, Subsurface drip Irrigation (15 cm depth) and Irrigation is Common (conventional area) in the main plot) and biological fertilizer of nitroxin (no fertilizer (control), 2, 4 and 6 lit.ha-1 in the Subplot). The results of this study showed that simple and interaction effects of biological fertilizer application of nitroxin and irrigation management were significant in all measured traits. In order to use optimal water resources, diamond irrigation method (Subsurface drip Irrigation) can be used to reduce irrigation losses and achieve high yield in saffron production. The effects of irrigation management of Subsurface drip Irrigation diameters with biological fertilizer of nitroxin 4 lit.ha-1 were superior to other treatments, so that the highest yield of saffron stigma was observed in this treatment with 5.8 kg.ha-1.
