| Abstract Bio-fertilizers can be expected to reduce the use of chemical fertilizers and pesticides, but they are not yet able to replace their use. Bio-fertilizer production is cheap and does not create pollution in the natural system. Plant growth promoting fungi (PGPF) play important roles in plant nutrition, soil biology and soil chemistry, (PGPF) enhanced photosynthetic rate and other gas exchange-related traits as well as increased water uptake. PGPF are common root-associated and soil-borne fungi from diverse genera, which have the natural ability to stimulate various growth related traits of plants. Plant growth promoting fungi (PGPF) were isolated from various soils of Aswan University Campus, South–western Desert, Aswan, Egypt. The purified isolates were classified as Trichoderma longibrachiatum and Fusarium solani according to phylogenetic analysis and were used as bio fertilizers and to enhance Vigna unguiculata growth under irradiance stress. In current study it was found that these isolates improve V. unguiculata growth under irradiance stress through increasing chlorophyll content compared to control and showing maximum photosynthesis rate (Pn) at high Photosynthetic Active Radiation (PAR). It was concluded that Trichoderma longibrachiatum and Fusarium solani possessed multiple beneficial effects for V. unguiculata productivity when grown under harsh environmental conditions. | ||||
