Abstract

Nematodes are soil biota that are sensitive to changes in microenvironmental conditions, so that their population and diversity can reflect the dynamics of agricultural ecosystems. This study aims to analyze the total density, community structure, and genus of nematodes in two shallot (Allium cepa L.) planting fields in Bagor District, Nganjuk Regency, which have varying microenvironmental conditions: Field 1 (Balongrejo) and Field 2 (Ngumpul) Soil sampling was carried out periodically for 15 weeks. Nematodes were extracted using the Baermann funnel method and their genus was identified. The results showed that the minimal elevation difference and similar soil temperatures did not create an environmental gradient significant enough to significantly affect the diversity of nematode genera. The nematode population in both fields was dominated by non-parasitic groups (bacterivores and fungivores), indicating high organic matter decomposition activity. The observed differences in total population density were more strongly influenced by micro-edaphic factors, such as soil moisture levels and differences in pH, which are the main determinants of nematode mobility and reproductive activity. It was concluded that soil moisture and pH factors have a more dominant role in determining population density compared to temperature and altitude, which are not significantly different.
