Abstract

The efficacy of bio-agents on dry root weight of cowpea (Vigna unguiculata (L.) Walp) studied consecutively for three year at bundelkhand region showed maximum increase in the dry weight of root due to Trichoderma harzianum followed by Trichoderma viride at various doses. Both the biological agents acted more effectively at 10 to15 g dose. The study also revealed that T. pseudokoningii and T. koningii did not visualize any significant difference in their efficacies when compared with each other. Aspergillus flavus and Aspergillus niger were least effective in comparison with other bioagents
