In this study, potential and effective strains of Trichoderma such as T. harzianum (Th. Azad) and T. viride (01PP) have been investigated and their effect of pre sowing seed treatment on germination, seedling establishment, seedling dry weight and vigour in chickpea genotype (Radhey) was observed. The different pre sowing seed treatments showed different responses against all seven seed quality parameters. Chickpea seeds were treated with different concentrations of Trichoderma bioformulation such as 5%, 10%, 20% gm/kg seed followed by treatment with 0.2% Bavistin. As a result, the percentage of seed germination was found to be higher in T. harzianum (Th. azad) & Trichoderma viride (01PP) treated seeds with 5% bioformulation as compared to the other concentrations. Various attributes with their observations include seed germination (92% and 90%), root length (12.38 and 12.19 cm) shoot length (4.97 and 4.32 cm) seedling length (17.38 and 16.50 cm), dry weight (1.19 and 1.88 cm), vigour index I (5197.12 and 1485) and vigour index II (109.48 and 169.20). Among all treatments, control showed the poorest performance for all seven seed quality attributes.
