Abstract

In order to investigate the effect of different nitrogen sources on some quantitative and biochemical characteristics of Saffron, an experiment was conducted based on randomized complete block design with three replications at the Research Farm of Zanjan University. The treatments were Azotobarvar-1 biofertilizer (containing free-living nitrogen-fixing bacteria Azotobacter vinelandii) at two levels (0. 1 and 0. 2 %), Nitrokara (containing symbiotic and free-living nitrogen-fixing bacteria Azorhizobium caulinodan) at two levels (1 and 2 %), and combination of both at four levels (1% Nitrokara + 0. 1 % Azotobarvar-1, 1 % Nitrokara + 0. 2 % Azotobarvar-1, 2 % Nitrokara + 0. 1 % Azotobarvar-1, 2 % Nitrokara + 0. 2 % Azotobarvar-1) compared to control and one nitrogen level (40 kg/ha) in the form of urea. The results showed that the highest number of flowers, performance of stigma and the maximum length of stigma was Obtain from plants inoculated with 0. 2 % Azotobacter. The highest leaf nitrogen content and chlorophyll a obtained in 0. 2 % Azotobacter and 40 kg/ha nitrogen. Also 0. 1% Azotobacter and 2 % Azorhizobium treatments resulted in highest dry weight of stigma. The highest amounts of antioxidant and total Phenol of stigmas were achieved with 1 % Azorhizobium and the highest amount of Flavonoids was observed with 0. 1 % Azotobacter. The Highest amounts of Crocin and Safranal were obtained with 0. 1 % Azotobacter and 1 % Azorhizobium treatments respectively. In general, to obtain higher production of saffron 0. 2 % Azotobacter, and to achieve higher content of active substances 0. 1 % Azorhizobium are recommended.
