Evaluation of Simultaneous Application of Arbuscular Mycorrhizal Fungi and Biochar on Growth, Yield and Concentration of Aloin of Aloe vera L.

In order to evaluation of simultaneous application of biochar and Arbuscular mycorrhizal fungi (AMF) on the growth, yield and concentration of aloin of Aloe vera at different growth stages under greenhouse conditions, a factorial experiment was conducted in a completely randomized design with four replications. Treatments included biochar at three levels (0 (control), 250 and 500 g per pot) and AMF at two levels (non-inoculation and inoculation). AMF inoculation without biochar application has a significant effect on traits compared to other treatments at both harvest times, the number of leaves were 28 and 19%, leaf fresh weight 41 and 36%, gel fresh weight 40 and 34%, gel dry weight 57 and 74%, fresh weight of root 65 and 69% compared to control plants. The result showed the highest concentration of aloin was obtained in the treatment of 500 g of biochar with inoculation with AMF. Also, the highest amount of soluble carbohydrates in dry gel in the second (62.40 mg/g) was obtained in the application of 500 g of biochar with AMF inoculation. According to the results of this experiment, inoculation of roots with AMF can be useful to increase the growth and yield and quality of A. vera, but the use of biochar, especially in high amounts, had a negative effect on A. vera.
