ABSTRACT

A field study was undertaken to isolate the fungi present in the rhizosphere of cowpea plant grown from stored cowpea seeds. Periodically stored cowpea (3, 6, 9 and 12 months) seeds were sown in the field and rhizospheric soil was collected at five different growth stages (15, 30, 45, 60, 75 days after sowing) of the plants for the isolation of fungal flora. Result revealed that, fungal population was less at 15 days after sowing (DAS) which was gradually increased upto 45 DAS and decreased gradually from 60 DAS. The rhizosphere soil was associated with Aspergillus sp., Alternaria sp. Penicillium sp. Chaetomium globosum, Curvularia lunata, Fusarium solani, Helminthosporium solani, Monilia sp., Rhizopus sp. and Verticillium sp. in all the growth stages of plant. Therefore, present study confirmed that there is gradual increase in the fungal flora from seedling stage to maximum vegetative stage of the plant and decrease towards senescence stage.
