Abstract
The nutrient pool and soil organisms are highly affected due to declining soil
health. Reduction of fertilizer use efficiency is the reflection of injudicious use of
agrochemicals for crop nutrition and protection, such activity lead to lower organic
carbon content in soil. Restoration of soil health, lowering down chemical fertilizer
requirement and enhancement of microbial activity was thought and attempted in
present study using native plant growth promoting fungal isolates (PGPF). Fungal
cultures were isolated from different AAU farms based on their abilities to solubilize
P and K mineral forms. They were further screened for pathogenicity symptoms on
seed germination and seedling growth parameters. Two non-pathogenic fungi were
identified as isolate T-3, Aspergillus flavipes (NCBI Access No. MW88450) and
T-17, Trichoderma aggressivum (NCBI Access No. MW88453).
