oai:ojs.periodicos.ufpa.br:article-12162019-03-06T01:43:28Z BIOMASS PRODUCTION AND NUTRIENT CONTENT OF THE BEAN (Canavalia ensiformis (L.) DC.) IN REFORESTATION IN PARÁ STATE PRODUÇÃO DE BIOMASSA E TEOR DE NUTRIENTES DO FEIJÃO-DE-PORCO (Canavalia ensiformis (L.) DC.) EM REFLORESTAMENTO NO ESTADO DO PARÁ Rayol, Breno Pinto Alvino-Rayol, Fabrízia de Oliveira ABSTRACT: The objective of this study was to evaluate biomass production and nutrient content of jack bean (Canavalia ensiformes (L.) DC.) as a green manure intercropped with paricá (Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby). The experiment was carried out in an experimental area at the Vigia municipality (Pará state, Brazil). The jack bean was sown between rows of planted paricá spaced 4mx4m. The plants were evaluated to shoot biomass production, nutrient contents in leaves of jack bean. Shoot fresh and dry biomass production of the evaluated specie were 25.4 t.ha-1 e 4.8 t.ha-1, respectively.The average concentrations of nutrients were 44.26 g.Kg-1 (N); 3.01 g.Kg-1 (P); 16.3 g.Kg-1 (K); 9.88 g.Kg-1 (Ca); 3.11 g.Kg-1 (Mg), 28 mg.Kg-1 (Cu); 61 mg.Kg-1 (Mn); 175 mg.Kg-1 (Fe) and 41 mg.Kg-1 (Zn). The results of biomass productions and above-ground nutrients of jack bean show that this species has potential for use as green manure in agroforestry systems and reforestations areas. KEY-WORDS: cover legumes, mulch, nutrients. RESUMO: O objetivo deste estudo foi avaliar a produção de biomassa e teor de nutrientes do feijão-de-porco (Canavalia ensiformis (L.) DC.) consorciado com o paricá (Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby) no estado do Pará. O feijão-de-porco foi semeado nas entrelinhas de paricá cultivado em espaçamento 4m x 4m. Foram observadas a produção de massa seca da parte aérea e a concentração de nutrientes do tecido vegetal das folhas do feijão- de-porco. A produção média de massas fresca e seca da parte aérea do feijão-de-porco foi de 25,4 t.ha-1 e 4,8 t.ha-1, respectivamente. As concentrações médias de nutrientes contidas no tecido vegetal de feijão-de-porco foram: 44,26 g.Kg-1 (N); 3,01 g.Kg-1 (P); 16,3 g.Kg-1 (K); 9,88 g.Kg-1 (Ca); 3,11 g.Kg-1 (Mg), 28 mg.Kg-1 (Cu); 61mg.Kg-1 (Mn); 175 mg.Kg-1 (Fe) e 41 mg.Kg-1 (Zn). Os resultados de produção de biomassa e de nutrientes da parte aérea do feijão-de-porco associado ao paricá revelam que esta espécie possui potencial para uso em adubação verde em áreas de reflorestamento. PALAVRAS-CHAVE: cobertura morta, leguminosa de cobertura, nutrientes.
