Abstract: Wheat faces many problems due to biotic and abiotic factors. Low seed germination is a severe problem which directly affects its yield and quality. Trichoderma is known as bio-control agent of phytopathogens but also act as plant growth promoter due to its many direct mechanisms. In present study wheat seeds were primed with three isolates of Trichoderma harzianum (Trico Pak, BDF 22and BDF43) to check their impact on seed germination and plant vigor. Results showed that application of Trichoderma has no negative impact on seed germination rather it not only enhances the rate of seed germination but also gave vigor to wheat plant and improve shoot and root growth. Isolate BDF22 showed maximum seed germination after 48 hours followed by other tested isolates with respect to control under in-vitro studies. Wheat plants treated with isolate BDF43 were erect and vigorous as compared to others. In-vivo results proved that isolate BDF22 gave maximum (92%) seed germination as compared to other tested isolates. On the bases of results, it is concluded that Trichoderma application enhances the growth rate of wheat seeds with no negative impact.
