تأثیر استفاده از کود گوگرد و تیوباسیلوس بر برخی صفات سیر محلی ساری

To investigate the effect of thiobacillus bacteria and sulfur fertilizer on yield and some characteristics of local garlic of Sari, an experiment as factorial based on Randomized Completely Block Design with three replications was carried out in 2013 in Sari. Factors was sulfur in three levels (zero, 50 and 100 kg per hectare) and inoculation with thiobacillus bacteria in two levels (inoculated and none inoculated). In this research bulb diameter, plant height, fresh weight of shoots, bulbs fresh, weight, number of cloves and percentage of sulfur was studied. The results showed that bulb diameter (α=0.01), plant height and bulbs fresh weight (α=0.05) was affected by inoculation with thiobacillus bacteria. bulb diameter (α=0.01) and bulbs fresh weight (α=0.05) was affected by sulfur fertilizer. Iinteraction between inoculation and sulfur showed no significant differences in all traits. The highest bulb diameter, plant height and bulbs fresh weight was related to the clove which was Inoculated with thiobacillus bacteria with 46.26 mm, 69.77 cm andd 44.34 gr. The lowest amount of this traits belonged to none Inoculation with 43.53 mm, 41.71 gr and 66.5 cm respectively. The highest of bulb diameter and fresh weight of was related to consumption of 100 kg per hectare sulfur with 45.83mm and 44.70 gr.
