Effect of Trichoderma harzianum on Mineral Component and Antioxidant Activity of Tomato Fruits
Tomato is one of the important vegetable crops with good nutritional quality and antioxidant activity. Soilborne pathogen Rhizoctonia solani that infect tomato plant reduced the uptake of mineral nutrient from the soil and ultimately reduced their quality. Trichoderam spp. is the most potent biocontrol agent of this pathogen used for the management of this pathogen. In this experiment we studied the effect of Trichoderma-plant-R. Solani interaction on mineral content, nutritional quality and antioxidant capacity of extract of tomato fruits. We used two Trichoderma harzianum isolates i.e. BHU51 and BHU105 and their consortium for the study. Results clearly showed that the Trichoderma treated plant fruits had greater mineral content and antioxidant activity than pathogen inoculated control. The consortium of Trichoderma treated plants fruits had the maximum mineral content and their quality, it might be due to the synergistic effect of Trichoderma isolates that reduced the incidence of R. solani in better ways than single Trichoderma isolate..
