The effect of inoculation with Trichoderma harzianum and Trichoderma viride and Glomus mosseae on same growth parameters of tomato plants (Solanum lycopersicum L.)

Abstract

   This study was conducted to evaluate the effect of Trichoderma harzianum and Trichoderma viride, and two isolates of   Glomus mosseae   (G1 and G2) fungi and their combination on the concentration of the tomato foliage system (Solanum lycopersicum L(.The results revealed that all tested bioagents and their combination induced significantly increased all test growth parameters compared to the control treatment. The results also showed that the dual inoculation with Trichoderma harzianum + G1 , Trichoderma harzianum + G2 recorded significant superiority over all tested treatment in the concentration of the macro elements which recorded 480 and 468.33 % for total Nitrogen content  0.483 and 0.400 % for Phosphorus  content 4.296 , 4.253 % for Potassium and the micro elements which recorded  19.67 and 17.67  mg/kg, 42.13 and 40.18 mg /kg  , 167.67 and 158 and  2235 and 2112.7 in addition to  leaf area and chlorophyll concentration that     recorded  ( 41.36 and  mg/kg 30.83 ) cm² /plant ( 25.65 and 20.5 ) mg/gm  respectively Compared to control treatment, which recorded of 308 % total nitrogen, 0.116  % phosphorus total, 2.3  % total potassium, (Fe 1367, 45 Mn, 21.02 Zn  and 7 Cu)) mg / kg and 10.86 cm² / leaf area, 9.03 mg / g Chlorophyll concentration respectively.
