Abstract
Sustainable agriculture production is the most crucial development program of countries in arid and semi-arid regions of the world. Therefore, this Research-Extension project was implemented to extend the former research findings (RF) in the rainfed fields of West Azerbaijan province in the crop season of 2021-2022 for one year. The inoculum of AMF consisted of a combination of three species of Funneliformis mosseae, Claroideoglomus etunicatum, and Rhizaphagus irregularis at a rate of 2% (two kg of inoculum/100 kg of seeds) and GB foliar applications with a concentration of 100 mM (equivalent to 11.71 g/ L) were applied in two growth stages of wheat, the first stem node (code 31 Zadox) and the developmental stage of pregnancy (code 49 Zadox). The results showed that the RF treatment increased grain yield by 355 kg/ha compared to the control (P≤0.05). The characteristics of the harvest index, the number of spikes/m2, and the weight of 1000 seeds increased by 5.13%, 18.10%, and 11.44% respectively, compared to the control (P≤0.05). Also, in the RF treatment, the uptake of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), zinc (Zn), and copper (Cu) nutrients increased significantly compared to the control (P≤0.05). Therefore, inoculation with AMF in combination with GB foliar application could be a sustainable approach to increase the yield and improve wheat crops quality under the same conditions as this experiment.
