The present research was carried out to assess the effect of Nitrogen, Phosphorus and Potassium (NPK) as inorganic fertilizers and Palm Bunch Ash (PBA) as organic amendment on the population of parasitic nematodes in soil and yield of plantain. Soil samples were collected randomly, from a distance of 20 cm and 40 cm from the plants, which had received NPK and PBA. Samples were taken at the two depths of soil: 0-20 cm and 20-40 cm. Nematodes were extracted by the Whitehead and Hemming’s method. Genera of nematodes identified included Pratylenchus, Paratylenchus Meloidogyne, Hellicotylenchus and Radopholus spp. No significant differences regarding nematode populations in the soils taken at 20 cm length from the plants, but there are significant differences in soil samples taken from 40 cm length. The highest nematode population was recorded in the treatment with an application of urea and PBA. There was a decrease in number of tiers per bunch and fruits per tier of plantain. Differences regarding nematode numbers are due to fertilization, which determine development of plantain roots system and high concentration of nutrients in the soil.
Key words: Nematodes, plantain production, NPK, urea, palm bunch ash, lixisol.
