An experiment was carried out in aplastic house near the Technical institute of Al-Mussieb during the growing season 2012-2013 using eggplant (Solanum melongena L.) To study the effect of adding two kinds of decomposed organic fertilizers (animal ,plant and mixed 1:1) alone or with the Trichoderma harzianum fungus on growth , yield and severity of disease caused by the root-rot fungus Rhizoctonia solani on eggplant.
The study included eight treatments are added to the first T. harzianum fungus. to the second plant decomposed fertilizer, to the third plant added fer + T. harzianum fungi. To the fourth added animal fer ,to the fifth added animal fer. + T. harzianum fungi ,to sixth mixed plant and animal fer,to the seventh mixed plant and animal fer.+ T. harzianum fungi and the eight treatments leaves without any additions (compared). The complete CRBD with three replications was used and the means was compared by L.S.D test on 0.05%.
The result showed that the treatment of adding mixture of organic fer. with T. harzianum fungus had significant effect in improving all the parameter studied (length of vegetable shoot and root system of plant . number of branches \ plant ,wet weight of vegetable growth, dry weight of root and weight of yield) by104.66cm ,36.62cm, 7.10 branches \plant, 598.85 cm. 191.12 gm , 212.89 gm, 69.47gm and 4.02 ton. Donum-1, respectively in comparison treatment by 82.5%
The results also showed no difference between the treatment of adding animal fer. T. harzianum fungus in tall of vegetable growth, weight of wet vegetable, number of branch, weight of dry root and weight of yield by 94.4 cm , 533.8 gm, 6.8 branch \plant 64.81gm and 3.7 ton. Donum-1, respectively.
