- Saffron (Crocus sativus L.) is an autumnal flowering geophyte whose dried stigmas, well known for their aromatic and colouring power, have been used since immemorial time as a spice in human nutrition, for medicinal purposes and as a dye Its quality depends on the concentration of three major metabolites: crocin, safranal and picrocrocin which are responsible for colour, aroma and bitter taste of saffron, respectively. The use of saffron as a medicinal plant has a long history and it has been used as a sedative and analgesic in traditional medicinal preparations [1]. In order to investigate the effects of different fertilizers on secondary metabolites of saffron an experiment was conducted in experimental field of Payame Noor University based on completely randomized design (CRD) with three replications. Treatments were three different fertilizers including control (without any fertilizer), 100-250 Kg/ha N-P205 (Chemical fertilizer), 12 and 6 t/ha for FYM (Farm Yard Manure) and vermicopost (organic manures), respectively. After flower harvesting, the separated stigma were dried and amount of crocin, safranal and picrocrocin was determined using UV–vis spectrometric method [2]. The application of chemical and non-chemical fertilizers improved the production of secondary metabolites compared with control in saffron. Based on results the effect of treatments on crocin was significant and vermicompost resulted highest and lowest amount of crocin measured in control treatment. Safranal content of stigma did not affect by treatments, but highest amount of safranal observed in vermicompost and chemical fertilizer, whereas the lowest amount observed in control. Effect of experimental treatments on picrocrocin also was significant and highest amount of this component observed in vermicompost. The results indicated that the use of vermicompost as a bulky organic manure can enhance the production of secondary metabolites and improve antioxidant activity of this herb.
