Effect of Inoculum Levels of Trichoderma harzianum (T.26) on Tomato Growth and Yield Productivity

Abstract

A field experiment was carried out to evaluate the effect of three levels of Trichoderma harzianum fungus (1,2,3)g.plant (isolationT26)had been carried out to evaluate the growth plant and the productivity on tomato Olga variety under field condition. The results showed that the inoculation in levels 1 and 2 g.plant-1 cause a significant increase in tomato growth indicators(Plant height, number of branches, leaf area and relative chlorophyll) With a significant superiority level 1 g.plant-1 which it recorded 105 cm ,6.0 branch ,60.21 cm2 and 46 spad.unit compared with 3 g.plant-1 level and control treatment which gave (64,60)cm , (1.3,2.0)branch ,(10.90 ,10.96) cm2 and (31 ,34) spad.unit for each them respectively . The results also showed that inoculation Levels 1 and 2 g.plant-1 Cause a significant increase in both of quantitative and its components indicators in plants which included number of clusters fruiting, number of harvested fruits, number of fruits, weight of fruit, yield of plant and total yield With a significant superiority level 1 g.plant-1 on 2 g.plant-1 level which it recorded 7 cluster ,10 Harvested , 36 fruit ,0.17 kg.fruit-1,6.12 kg. plant-1 yield of plant in control treatment compard with 3 g.plant-1 level on one hand and control treatment from the other side when it recorded (2,2) cluster ,(2,2) branch 10 Harvested , (7,8) fruit.plant-1 ,(0.13,0.14) kg.fruit-1,(0.98,1.04) kg. plant-1 yield of plant for each of them respectively .
