In order to detect the effect of the nematode on the growth and chemical composition of Coffea arabica L., cultivar Mundo Novo, 376/4-IAC, young plants were cultivated in pots containing two different soils - Terra Roxa Estruturada (a clayished soil) and Podzolico Vermelho Amarelo - Laras (a Sandy Soil). Three levels of nutrients were applied: level 0 - no fertilizer added; level 1 - fertilization recommended usually for the crop; level 2 - heavy fertilization. Half of the plants were latelly inoculated by adding organic mater containing the nematodes. After 420 days all plants were harvested, measured and analysed for N, P, K, Ca, Mg, B, Cu, Fe, Mn e Zn. Fertilized trees present no difference on the growth in the presence of the nematodes. The absorption of Zn and B were severely affected in the presence of the nematode on the sandy soil, even when fertilized. On the clayished soil the nematodes depressed only the absorption of Zn. Diseased plants grown on the sandy soil presented a higher content in Mn than the healthy ones.
