“…The study revealed the presence of trophic groups comprising of herbivores, fungivores, bacteriovores and omnivores-predaceous. The distribution of nematodes in the agro-ecosystem was similar to the nematodes reported by Wu et al, (2008) and Lawal and Atungwu (2012). Application of organic amendment of composted plant materials stacked on poultry dung on eggplant field led to the development of a complex ecosystem which was found to be constituted by varying population of nematode species each with different feeding characteristics.…”

“…As major player in the soil food chain (Wu et al, 2008), nematodes have been reported to contribute immensely to the rate of decomposition of plant litter and turnover of nutrients from soil organic matter (Wu et al, 2008 andAtungwu, 2013) and many researchers have investigated into nematode communities in natural ecosystems and agro ecosystems including differences linked with land management practices (Liang et al, 2002 andOkada andHarada, 2007). Besides being a source of substrate on which other soil mesofuana feed (Atungwu et al, 2012), nematode population in agro-ecosystem can respond in a predictable way to ecosystem disturbance during land preparation and cultural practices involving incorporation of organic materials into the soil (Freckman and Ethema, 1993;Lawal, 2009 andAtungwu, 2013).…”

Nematode occurrence and distribution in an organically managed S. melongena L. field was evaluated. Collection of soil samples was achieved using a soil corer at depths 0-5cm and 6-10cm undisturbed and disturbed sites. Eggplant roots at various amendments were collected at 30, 60 and 90 days post application of organic amendment. the modified Baermann's method was used to extract nematodes from soil and root. There was variability of in depth related occurrence of nematode community composition, however, abundance and species diversity was highest at the 0-5cm depth and declined as depth increases at the undisturbed site (P<0.05). Also, at the disturbed site, nematode abundance and diversity was highest at the portion amended with 2kg of organic amendment and declined at the control portion (P<0.05). however, all amended portions with different dosages of organic amendment influenced nematode abundance and diversity. The study indicated that incorporation of organic amendment influenced the pathogenicity and establishment of feeding sites on the crops. Also, organic amendment influenced the species richness and relatively even distribution of nematodes in the study. Trophic affiliation and specific biotrophy of nematode community composition influenced the spatial and temporal distribution, species abundance and richness of the organism in the study.

“…Many organic material wastes represent an important resource of nitrogen, phosphorous, calcium and other elements as zinc, copper, magnesium essential to plant growth (Tester, 1990). There are sufficient data to indicate that organic materials have positive effect on soil structure, improve plant growth and yields and reduce disease impact caused by a wide range of plant pests including bacteria, soil-borne pathogens and phytoparasitic nematodes species (Akhtar & Mahmood, 1996;D'Addabbo & Sasanelli 1996aAbawi & Widmer, 2000;Renčo et al 2007Renčo et al , 2009Renčo et al , 2010Atungwu, 2012). In particular, the suppressive effect of soil amendments, with a wide range of composted waste materials, on plant parasitic nematodes was largely and frequently docu-mented, although an inconsistent nematode control or variable effects were also described in literature (Szczech et al, 1993;McSorley & Gallagher, 1995;Akhtar & Malik, 2000).…”

Use of organic soil amendments is a traditional agricultural practice for improving physical and chemical soil properties, soil structure, temperature and humidity conditions as well as nutrients content which are needful for plants growth. Application of organic materials to soil can cause a change in soil microflora and microfauna including soil nematodes. Nematodes, are the most ample and varied group of soil fauna. They are ever-present habitants of all soil types with high population densities. The changes in soil nematodofauna can results in an increase in the number of beneficial nematodes such as bacterial or fungal feeders and decrease and/or suppression in the occurrence of economically important plant parasitic nematodes. A variety of organic amendments, such as animal and green manure, undecomposed (raw) or decomposed materials (compost) are used for this purpose. Generally, plant parasitic nematodes have been controlled mainly by chemical soil fumigants and nematicides, agricultural practices or resistant cultivars. However, organic amendments can provide an environmentally friendly alternative to the use of chemical nematicides, which are often expensive, of limited availability in many developing countries and above all environmentally hazardous.
