Resumo: The objective of this work was to determine the rate of soil coverage, biomass yield and total accumulation of N, P and K in the aerial biomass of the legume Arachis pintoi Krapov. & W.C. Greg. The experimental design was a randomized block with four replicates arranged in a 2x4 factorial with two levels of row spacing (25 and 50 cm between rows) and four different planting densities (2, 4, 8 and 16 plants/m). Complete soil coverage was achieved 224 days after planting. Planting density affected the rate of soil coverage and the rate of dry matter and nutrient accumulation by the shoot tissue of the legume, but these parameters were not significantly affected by row spacing. The results suggest that the optimum planting density was 8 plants/m in rows spaced 50 cm apart.

Greg.), em diferentes densidades e espaçamentos de plantio. O delineamento experimental adotado foi de blocos ao acaso, em arranjo fatorial 2x4, com quatro repetições. Os tratamentos constaram de espaçamentos entre sulcos de plantio (25 e 50 cm), e de densidades de plantas (2, 4, 8 e 16 plantas/m linear). A cobertura total do solo ocorreu aos 224 dias após o plantio. Foram constatadas diferenças de densidades de plantio na taxa de cobertura do solo, produção de biomassa e acúmulo de nutrientes na parte aérea do amendoim forrageiro. Todavia, não foram observadas diferenças quando se variou o espaçamento entre sulcos. Entre as alternativas testadas, a densidade de 8 plantas/m linear no espaçamento de 50 cm entre sulcos de plantio foi a combinação mais adequada para a plena formação da cobertura viva com amendoim forrageiro.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPerin, AdrianoGuerra, José Guilherme MarinhoTeixeira, Marcelo Grandi2003-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6638Pesquisa Agropecuaria Brasileira; v.38, n.7, jul. 2003; 791-796Pesquisa Agropecuária Brasileira; v.38, n.7, jul. 2003; 791-7961678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6638/3695info:eu-repo/semantics/openAccess2014-08-11T19:16:33Zoai:ojs.seer.sct.embrapa.br:article/6638Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:16:33Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
