Abstract :
This study aimed to investigate the effects of two types of fungi on soybean function and morphology. This experiment was conducted in a factorial design with inoculation of two types of fungi, Trichoderma and mycorrhiza, at four levels: inoculation with Trichoderma, inoculation with Mycorrhizal, inoculation with both fungi, and the control, in three replicates. The experiment was performed in two crop years (2020 to 2022) in a research farm. After the physiological maturity of the parts, 10 shrubs from each treatment were randomly selected, and the macro- and micro-elements and the percentage of oil and protein were measured according to the standard method. Based on the results, chlorophyll a and b, the number of branches, dry weight, leaf area, pod length, stem diameter, number of pods per plant, number of nodes per stem, and height from soil to the first pod were higher in the soybean grown in soil containing double inoculation of the fungi than the other treatments and the controls. The yield was 1.98, 2.14, 2.85, and 1.7 tons per hectare, respectively. Protein content was 40.31, 42.74, 43.04, and 39.89%, and oil content was 2487, 25.24, 25.94, and 24.17%, respectively. The contents of macro- and micro-elements in soybean leaves and seeds were significantly higher in the biological fertilizer containing the two types of fungi than others. Given soybean's relatively wide area of cultivation in Mazandaran Province (Iran), the confirmed benefits of these fungi in improving the plant's growth and development, and the necessity of preserving production resources, the studied fungi can be a suitable alternative to chemical fertilizers.
