Effects of of fulvic acid and cow manure on stigma active components and petal Antiradical Activity of saffron (Crocus sativus L.)
components of saffron were evaluated under field conditions. Treatments were four levels cow manure (0, 10, 20 and 30 t.ha-1) and three fulvic acid (0, 5 and 10 kg.ha-1). This experiment was carried out as factorial based on randomized completely block design with three replications in research farm...

| Summary: | components of saffron were evaluated under field conditions. Treatments were four levels cow manure (0, 10, 20 and 30 t.ha-1) and three fulvic acid (0, 5 and 10 kg.ha-1). This experiment was carried out as factorial based on randomized completely block design with three replications in research farm of Birjand University, Iran, during cropping year 2015-2016. Results showed that cow manure improved the active ingredients of stigma (picrocrocin, safranal and crocin) in first year of study. Also, results showed that petal antioxidant compounds (total phenol and anthocyanin) and active ingredients of stigma were influenced by cow manure in second year of study. The highest safranal was obtained in plants treated with 10 t.ha-1 cow manure in first year of experiment. Results also showed that fulvic acid has a positive effect active ingredients of stigma (picrocrocin and crocin), anthocyanin and total phenol in two years of experiment and the highest rate of anthocyanin and total phenol were obtained with 5 kg.ha-1 fulvic acid while the lowest values were recorded in control. Application of different levels of cow manure and fulvic acid had a positive effect on the active ingredients of stigma in two years of experiment and anthocyanin and phenol in second year of study. Thus, results showed that cow manure and fulvic acid have significant impact on antioxidant compounds and active ingredients of saffron under field conditions. |
