Monitoring the biological quality of soils often include nematodes as bioindicators. The aim of this study was determined the influence of liming, P and Zn effect on nematode community structure as an indicator of soil ecosystem health in hot pepper. Pot experiment with hot pepper was conducted in randomized block design as follows: control, P, Zn, P + Zn, lime, P + lime, Zn + lime and P + Zn + lime (25 mg/kg P, 1 mg/kg Zn and lime as 2.22 g/kg CaCO3). The highest number of nematodes genera was with phosphorus application (17.25). The most common genera were Rhabditis and Tylenchus. Above all indices, only the Structure index (SI) shown significance (P < 0.01) in reflecting soil disturbance. The highest significant correlation was found between Maturity index 2–5 and Structure index <br />(r = 0.946***), Maturity index and Plant parasitic nematode and Maturity index ratio (r = –0.919***) and between Ecological and Channel index (r = –0.815***).
