In order to evaluation the response of saffron to different manure, biological and chemical fertilizers, an experiment was carried out as split-plot based on randomized complete blocks design with three replications in Research Farm of Gonabad Agriculture Jihad during 2015-2016 and 2016-2017 growing seasons. Main factor was 60 t/ha manure, and no manure application, and sub factor concluded of control (no fertilizer use), nitroxin (5 L/ha), biophosphorus (3 L/ha), biosulphur (5 kg/ha), humic acid (10 kg/ha), and chemical fertilizer (150, 100, and 100 kg/ha urea, triple superphosphate, and potassium sulfate). Experiment results indicated that interaction effect of manure and biological and chemical fertilizers on fresh flower yield, fresh and dry stigma yield was significant. The highest fresh flower yield (181 kg/ha) achieved by biophosphorus along with application of 60 t/ha manure. Fresh stigma yield in chemical fertilizer under manure application treatment showed the highest increase (mean yield of 10405 g/ha). While, dry stigma yield due to biophosphorus application obtained the highest value (5351 g/ha). The effect of manure on corm traits was significant. Corm number per unit area and corm yield showed 19% increase in second year due to manure application than control. Among biological and chemical fertilizer treatments, the highest value of corm number (440 corm/m2) and corm yield (4401 kg/m2) was obtained due to biophosphorus application. Based on obtained results, combined application of recommend manure with biological fertilizers especially biophosphorus under climatic and edaphic conditions similar to this experiment area is recommended.

In order to study the effect of bio-fertilizers, planting method and superabsorbent polymer on quantitative yield of saffron under rainfed condition, a factorial experiment based on randomized complete block design with three replications was conducted at the Agricultural Research Station of Khorramabad, Iran during 2015-2016 growing seasons. In this study, Nitroxin bio-fertilizer (consumption 5 Lit/ha and non-consumption), Stockosorb superabsorbent polymer (consumption 240 kg/ha and non-consumption) and planting method (streaking and cluster) was tested. Results showed that triple interactions was significant for number of corm/m2 in first and second year and combined treatment including non-Nitroxin in cluster culture method using superabsorbent with 80.67 corm/m2 for first year and with 183.67 corm/m2 for second year was the superior treatment. Results showed significant differences for number of produced flowers and for fresh and dry weight of stigma in both years; and in the first year, treatment included cluster method cultivation, consumption of superabsorbent and no consumption of Nitroxin was superior; while in the second year, superior treatment was use of superabsorbent, Nitroxin and cluster method. For stigma dry weight of saffron, triple interactions was significant and in the first year, cluster method and consumption of superabsorbent and no usage of Nitroxin was superior (with 0.6 kg/ha), and in the second year, use of Nitroxin and superabsorbent and cluster method was superior (with 0.719 kg/ha). In general, results of the present study in dry-farming conditions over the two years, cluster method cultivation with usage of superabsorbent and Nitroxin could be recommended. Reasons of this recommendation and introduction of the mentioned method are dry climate conditions in area of study and reduction in consumption of chemical fertilizers for development of sustainable agriculture.
