Fusarium wilt (Fusarium oxysporum f. sp. ciceris (Padwick) Matuo and K. Sato) is one of the major yield limiting factors of chickpea (Cicer arietinum L.). For eco-friendly and sustainable management of the disease, Trichoderma harzianum as commercial product (Biocont-T), used as seed coat and jointly amended in peat moss were evaluated against the pathogen. The study was carried out in the fields of Girdarasha research station (8.8 Km south of Erbil), College of Agriculture, Salahaddin University. A moderate Ascochyta-resistant chickpea cultivar (Flip 6-15) was used. The results showed that seed treatments with T. harzianum and peat moss amendments were significantly reduced the disease incidence and severity. An increase of growth rate, plant height, biological and seed yield was also occurred. Three quantities (500, 1000, 1500 g) of peat moss showed enhancements in terms of disease incidence and severity reduction and increased the growth rate and other plant agronomic parameters as compared to untreated control. Treatment efficiency towards the yield and percentage of disease inhibition (PDI%) between treatments were measured. Using 10 Bcnt, 1000 Ptms-Tri and 1500 Ptms treatments were the most efficient treatments to enhance yield. For PDI %, 1000 Ptms-Tri, 10 Bcnt1500 Ptms and 500Ptms-Tri, were showed high disease inhibition in the field.
