Methods of plant growth-promoting fungi application to enhance the growth and yield of wheat var. Ibaa99

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.

Comparative effect of Trichoderma hamatum and host-specific Rhizobium species on growth of Vigna mungo.

The present study was designed to investigate the combine effect of Trichoderma hamatum and host-specific Rhizobium sp. of Vigna mungo on growth and biochemical parameters of same legume. The results proved that T.hamatum and host-specific Rhizobium sp are compatible with each other and their combine use was found effective not only in improving the growth parameters including lengths of roots & shoots and fresh biomass of experimental crop but also increasing the total chlorophyll, carbohydrate and crude protein contents as compared to control plants (p<0.05). Similarly, the amount of both nitrogen and phosphorus was significantly increased in leaves of the same legume (p<0.05). Therefore, T.hamatum could be a good alternate of chemical fertilizer and fungicide for improving the growth and productivity of V.mungo.
