Summary
O objetivo deste estudo foi avaliar o potencial do feijão guandu, Cajanus cajan (L.) Millsp., como adubo verde e no manejo integrado de plantas invasoras em área de reflorestamento no estado do Pará. O experimento foi instalado no município de Vigia-PA, em delineamento inteiramente casualizado, com dois tratamentos e três repetições.O feijão guandu foi semado nas entrelinhas de Schizolobium amazonicum Huber ex. Ducke (paricá) cultivado em espaçamento 4 m x 4 m. Aos 30 e 90 dias após a semeadura do guandú, foram avaliados dois tratamentos: plantio sem guandu (SG) e plantio com guandu (CG). Foram avaliados a produção de massa seca da parte aérea, concentração de nutrientes do tecido vegetal das folhas do feijão guandu e o grau de infestação, riqueza e diversidade das plantas invasoras. A produção média de massas verde e seca da parte aérea da espécie avaliada foi de 16,1 t/ha e 11,5 t/ha, respectivamente. No que se refere à infestação, diversidade e riqueza de plantas daninhas, os melhores resultados foram encontrados no tratamento com Cajanus cajan aos 90 dias após a sua semeadura.
Summary translation
The objective of this work was to evaluate the potential of pigeon pea, Cajanus cajan (L.) Millsp. coverage as a green manure in the integrated weed management in reforestation in Pará State.The experiment was installed in the district of Vigia, Pará State, as a completely randomized design with two treatments and three replicates. Cajanus cajan was interplanted with seedling of Schizolobium amazonicum Huber ex. Ducke in a 4 m x 4 m spacing. After 30 and 90 days of sowing of legume coverage, two treatments were evaluated. The treatments were: no pigeon pea between tree lines and pigeon pea between seedling lines. The plants were evaluated to shoot biomass production, nutrient contents in leaves of pigeon pea, and degree of infestation, diversity and richness of weeds. Shoot fresh and dry biomass production of the evaluated specie were 16,1 t/ha e 11,5 t/ha, respectively. Regarding the infestation, diversity and richness of weeds, the best results were found in treatment with Cajanus cajan after 90 days of sowing of legume coverage.
