Due to their slight negative effects on the environment, environmentally friendly nematode control techniques have been suggested. In order to determine the effectiveness of moringa leaf extracts and vermicompost alone and together against the root-knot nematodes, Meloidogyne javanica in pepper, the experiment was carried out in a greenhouse at the Ambo Agricultural Research Center., according to the results, 500 gm vermicompost and 80 gm moringa provided the greatest reduction in gall number per root (8), egg mass per 10 g root (2), gall index (2), population density per 100 g soil (108), and nematode reproduction factor (0.05). Vermicompost 500g and moringa 60g were also effective when combined. Additionally, organic amendments have a favorable effect on plant biomass. The findings obviously show that vermicomposting with plant products is more advantageous in organic farming. It is useful to control the damaging nematodes as well as for the improvement of soil nutrients.
