Abstract
The present research was carried out to investigate the effect of tomato seed biopriming using six native Trichoderma isolates under laboratory conditions. The seeds of tomato were primed in Trichoderma isolates and as a control treatment seeds were treated in sterile distilled water. It was observed that all the six native Trichoderma isolates showed good performance with respect to growth, germination percentage and vigour index of tomato seedlings as compared to control. Among the different Trichoderma isolates tested, T5 isolate showed highest shoot growth (5.44 cm), root growth (3.74 cm), germination percentage (90.0%) and seedling vigour index (826.37) followed by T4 isolate. The lowest shoot growth (4.22 cm), root growth (3.07 cm), germination percentage (56.7%) and seedling vigour index (412.70) were recorded in untreated control.
