| In order to investigate the environmental biological control of soybean charcoal rot disease by using the mutated formulation of Trichoderma Harzyanum with gamma ray, factorial field experiments in a completely randomized block design for morphological traits was performed in a farm located in Islamshahr in 2018-2019. The experiment consisted of 12 treatments including control, application of commercial biological fungicide of Trichoderma, soybean and inoculation of mutant and non-mutant Trichoderma fungi in powder and granules. The results showed that the effect of treatments was significant for all soybean morphological traits. The use of Trichoderma fungi treatments increased the quantitative amount of morphological traits such as grain yield, total dry weight, number of pods per plant, number of sub-branches, plant height, number of seeds per pod, one thousand seed weight, number of seeds per plant, harvest index, protein content and oil content, so that the highest average grain yield belonged to granular mutant Trichoderma and powder mutant Trichoderma treatments with averages of 3531.25 and 3527.5 kilogram per hectare, respectively. The results also showed that the interaction of formulation and pathogen in the number of pods per plant in the treatments of granular mutant Trichoderma and pathogenic powder mutant Trichoderma with 47 pods had the highest rate. |
