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 response of saffron medicinal plant to planting density and different levels of manure, a two year experiment was conducted in split-plot as complete block design with three replications in 2015-16 and 2016-2017 in Gonabad area. Main factor consisted of 5, 10, and 15 cm plant spacing on row and sub factor was control (no manure application), and application of 0, 20, 40, and 60 t/ha cow manure. Experiment results showed that maximum value of fresh flower yield in first year (127.4 kg/ha) achieved in 60 t/ha and in second year (72.3 kg/ha) obtained from 40 t/ha manure application under 5 cm plant spacing in row. The highest fresh stigma yield in both years (10.300 and 5.383 kg/ha, respectively) was obtained due to high planting density (5 cm plant spacing in row) and 40 t/ha manure application. Also, dry stigma yield under this treatment with 2.300 and 1.770 kg/ha, respectively had more increase in both years than other treatments. The highest daughter corm number in both years (614 and 591 corm/m2, respectively) obtained from highest corm planting density. In first year, 40 t/ha manure treatment had the highest value (592 corm/m2) and in second year, 60 t/ha manure application showed the highest value (572 corm/m2). In first year, the highest corm yield with 22724 kg/ha achieved from 5 cm plant spacing in row and 40 t/ha manure. But, in second year the highest mean value (12429 kg/ha) obtained from the same planting density and use of 60 t/ha manure. Therefore, to achieve suitable economic yield in saffron cultivation, application of 40 t/ha cow manure in 20×5 cm planting density under climatic and edaphic conditions similar to this experiment location is suggested.
