Aims: The main aim of the study was to evaluate some methods of application of Aspergillus niger AD1 and Trichoderma hamatum T-113 for enhancing the growth and yield of wheat var. Ibaa99 in pots and field conditions. Methodology and results: Plant growth-promoting fungi (PGPF) loaded with peat moss were used at a rate of 100, 150 and 200 mL pot-1 or m-2 in filed soil; seed treatment (coating) with fungi suspension 19 × 107, soil treatment and combination of all the three methods was employed in the study. Wheat seeds were sown in pots and field plots during 2018-2019, and data regarding various growth and yield attributes were recorded. In both pot and field trials, the results revealed that the best treatments for the desired plant growth and yield attributes were peat moss 150 mL alone or in combination with soil and seed treatments. The soil physicochemical parameters were also improved after inoculation with selected fungal isolates in different application methods compared with un-inoculated control treatment in both pot and field conditions. Conclusion, significance and impact of study The PGPF play a vital role represented phytoremediation, phytostimulation and bio-fertilization. The isolates of PGPF, which were applied with peat moss at 150 mL to the pot and in the field alone or combined with seed treatment and soil application, were significantly the best effective method for improving wheat attributes.
