Consequence of Gibberellic Acid and Vermicomposting on Vegetative Development, Mineral Content and Features of Persian Shallot

Persian Shallot (Allium hirtifolium boiss) is a valuable medicinal plant that is native to Iran. This herb belongs to the Alliaceae family and a perennial herb. This research was conducted to investigate the effect of vermicompost and gibberellic acid on vegetative growth, mineral content and characteristics of Allium bulb. The results of this study showed that the highest level of leaf area (19.12 cm ² ) was related to 0.7 kg/m ² and (21.66 cm ² ) treated with 206 ppm of gibberellic acid, the most number of leaves (4.95) in the treatment of 410 ppm gibberellic acid, the most number of daughter bulb were (7.36), respectively, for treatment of 1.2 kg/m ² vermicompost and (7. 24) for 410 ppm treatments Gibberellic acid, the highest diameter of daughter bulb (10.82 mm) was related to 0.6 kg/m ² vermicompost treatment, the highest dry weight of bulb (1.92 gr) was 0.7 kg/m ² vermicompost, highest percentage bulb’s dry content (32.93%) was related to 1.2 kg/m ² vermicompost treatment and (33.72%) was related to 410 ppm of gibberellic acid, the highest amount of phosphorus (0.37%) was related to the treatment of 410 ppm gibberellic acid and the highest amount of potassium (1.92%) was related to 1.2 kg/m ² vermicompost treatment.
