Evaluation of the effects of composted broiler litter enriched with Trichoderma viride in management of Meloidogyne incognita (Kofoid and White) in spinach (Spinacia oleracea)

Abstract

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 a
decrease in the population of M. incognita were observed in the amended
soil (soil:composted broiler litter 22:1 v/v). Infested plants that were grown
in native soil showed a significant reduction in growth, whereas in soils
treated with nematicide, carbofuran 3% G the growth was moderate. The
abundance of soil microfauna and naturally occurring nematophagous fungus,
T. viride significantly increased in amended soil when compared to the
soil treated with chemical nematicides. This study concludes that composted
broiler litter (soil:composted broiler litter 22:1 v/v) enriched with T. viride
increased the plant growth and abundance of soil microfauna and reduced
the population of M. incognita. Therefore, treatment with T. viride might be
more effective than the use of recommended level of chemical nematicides.
