Objetivou-se, neste trabalho, avaliar o crescimento, a produção do cafeeiro e a transferência de N da leguminosa para a cultura, sem a interferência do consórcio. Cultivaram-se cafeeiros em vasos, adubados com parte aérea de feijão-de- porco, enriquecido com 15 N em casa de vegetação, nas doses de 146 e 584 g planta -1 , complementados com 30% de adubação mineral. O feijão-de-porco promoveu aumentos da produtividade do cafeeiro, dos teores de Ca 2+ , soma de bases, CTC efetiva e matéria orgânica do solo. Os teores foliares de N derivado do feijão-de-porco, cinco meses após a adubação, foram de 4,68% e 18,65% nas doses respectivas de 146 e 584 g planta -1 . O percentual foliar, de N derivado do feijão-de-porco, nos cafeeiros é proporcional à dose fornecida.
The aim of this study was to evaluate the growth and production of coffee tree and transfer of N from biomass legumes to coffee tree cropping without the interference of field consortium. Coffee trees were cultivated in pots, and after shoots of jack bean, enriched with 15 N into the pots in greenhouse, at doses of 146 and 584 g plant -1 , supplemented with 30% of mineral fertilizer. Jack-bean promotes increases coffee yield, the best index of soil quality (concentration of Ca 2+ , sum of bases, effective CEC, soil organic matter). Foliar N content derived from jack-bean, five months after fertilization, were 4.68% and 18.65% at the respective doses of 146 and 584 g plant -1 . The percentage of N derived from jack bean in coffee leaves is proportional to the applied dose.
