For evaluation of response of flower and corm yield of saffron to nanobiologic fertilizer application methods in comparison to cow manure and chemical fertilizer an experiment was conducted in Shadmehr region as randomized complete block design with 10 treatments with four replication during two years (2014-2015 and 1015-2016). The treatments were 1. Corm inoculation with nanobiofertilizer (Bioumik product of Biozar company), 2. Corm inoculation+use in irrigation water, 3. Corm inoculation+ foliar application 4. Corm inoculation+ foliar application+use in irrigation water, 5. In irrigation water, 6. Foliar application 7. Use of chemical fertilizer (Urea, Ammonium phosphate and Potassium sulphate) 8. Use of cow manure 9. Use of chemical fertilizer +Use of cow manure and 10. Control. Studied traits were corm dry yield, flower dry yield, stigma dry and fresh yield and flower number. Based on result from third year the highest stigma dry yield (about 14 kg/ha) and flower number were achieved in Corm inoculation+ foliar application+use in irrigation water treatment (by 176 % increase in comparison to control) and the highest corm yield was seen in corm inoculation treatment (by 41 more than control). Results showed that the best method for corm improvement was corm inoculation with nanobiofertilizer and for flower improvement it is recommend to use of Corm inoculation+ foliar application+use in irrigation water.

In order to study the effect of planting density on flower and corm yield of Spanish and Iranian saffron (Crocus sativus L.) types, an experiment was arranged in factorial with randomized complete block design with three replications. This experiment was conducted on the Research Farm of the Faculty of Agriculture, Ferdowsi University of Mashhad in 2013-15. The saffron corm type was considered in two levels (a1: Iranian corm and a2: Spanish corm) and the planting densities were in three levels (d1:40, d2:48 and d3:60 corm.m-2). The two year results showed that the effect of different planting density and saffron corm types on the number of flowers, flower fresh and dry weight (stigma + style) and number of replacement corms were significant (P<0.01) while, the effect of corm type on fresh and dry weight of replacement corms was not significant. The highest number of flowers (30.25 No.m-2), flower fresh weight (15.125 g. m-2) and (stigma + style) dry weight (0.16 g.m-2) were obtained in d2 (48 corm.m-2), respectively. Corm type had significant effects on saffron flower characteristics. The highest numbers of flowers (27.21 No.m-2), flower fresh weight (13.58 g.m-2) and (stigma + style) dry weight (0.144 g.m-2) were obtained from Iranian corms (a1), respectively. However, the highest number (222.83 No.m-2), fresh weight (694.92 g.m-2) and dry weight (270.32 g.m-2) of replacement corms were obtained from Spanish corms (a2), respectively. The years had significant effects on saffron flower and corm characteristics as the highest amounts were obtained in second year (Y2), respectively.
