Abstract:
In the present study Plant Growth Promoting Fungi (PGPF) were isolated from the rhizospheric soil of rice. Five PGPF were isolated and different plant growth promoting traits were screened. Among them PS2 showed the best PGP traits like phoaphate solubilisation, IAA, HCN, ammonia, siderophore production etc. PS2 was identified as Penicillium commune by18s r DNA sequencing. Further experiments were carried out with PS2.For pot culture assay healthy Black Gram- Vigna mungo (L.)Hepper seeds were inoculated with PS2. The PS2 treated seeds exhibited better germination percentage and seedling vigour index than the untreated control. After 30 days of treatment plant showed better root, shoot length, biomass production and photosynthetic efficacy over the control. In present day modern agricultural system is trying to find out the alternatives to reduce the detrimental effects of chemical fertilizers. So, PS2 may be used as a potent biofertilizer to overcome this problem.
