In order to investigate the effect of Piriformospora indica and different levels of salicylic acid on morphological characteristics and activity of antioxidant enzymes of thyme (Thymus vulgaris L.) irrigation cut-off stress, an experiment has been conducted in the water year 2016, which has employed a split factorial experiment based on randomized complete block design with four replications in the research farm of dehloran Agricultural Research Center. The treatments consisted of four levels of salicylic acid (0, 150, 300 and 600 μm) as foliar application and a mycorrhiza fungus agent at two levels of inoculation and non-inoculation and irrigation cut-off stress at three levels (irrigation at 90, 50 and 30% filed capacity). The results of this study showed that with increasing irrigation cut-off stress up to 30% filed capacity plant height, Total weight of shoot, Number of leaves, Colonization percentage, and also the enzymes Catalase and Peroxidase Decreased. inoculation and treatment with salicylic acid up to a concentration of 300 μM could significantly reduce the destructive effects of irrigation cut-off stress on these traits However, increasing the concentration of salicylic acid to the level of 600 μM intensified the effects of irrigation cut-off stress and prevented the positive effects of the fungus.

In order to investigate the effect of biological and organic fertilizers on the yield (quality and quantity) of chicory forage under rainfed condition, a factorial experiment was conducted at Urmia University based on randomized complete block design with three replications in 2016. Treatments included control, Mycorrhiza (AMF), Thiobacillus bacteria (Thio), AMF+Thio, Vermicompost (V), AMF+V, Thio+V and AMF+Thio+V that their effects were evaluated in two growth stages (before stem elongation and full flowering). In comparison with control, the AMF+Thio+V increased dry forage yield, dry matter digestibility, crude protein yield and water soluble carbohydrates yield 99.72%, 143.21%, 68.54% and 76% in full flowering stage, respectively, and this treatment had lowest acid detergent fiber content at both growth stages among all treatments. In general, the use of Mycorrhiza and Thiobacillus together with vermicompost, improved the quantitative and qualitative performance of chicory forage in rainfed condition.
