In this study, repeat screenâ€house experiments were carried out to evaluate the effects of composted broiler litter enriched with Trichoderma viride in management of Meloidogyne incognita (Kofoid and White) in spinach(Spinacia oleracea). A significant increase of plant growth in S. oleracea and adecrease in the population of M. incognita were observed in the amendedsoil (soil:composted broiler litter 22:1 v/v). Infested plants that were grownin native soil showed a significant reduction in growth, whereas in soilstreated with nematicide, carbofuran 3% G the growth was moderate. Theabundance of soil microfauna and naturally occurring nematophagous fungus,T. viride significantly increased in amended soil when compared to thesoil treated with chemical nematicides. This study concludes that compostedbroiler litter (soil:composted broiler litter 22:1 v/v) enriched with T. virideincreased the plant growth and abundance of soil microfauna and reducedthe population of M. incognita. Therefore, treatment with T. viride might bemore effective than the use of recommended level of chemical nematicides.
