Summary: | A greenhouse experiment was carried out with perennial soybeans in a dark-red latosol, using a 25 factorial design, with 3 replications. The objective of this experiment was to study the effect of micro-nutrients, magnesium and lime on growth and symbiotic N2 fixation in perennial soybeans. The following criteria were used to determine the best treatment: dry matter production, total N, nodule weight and % of N, P, K, Ca and Mg in the stems and leaves. Lime had a positive effect on dry matter production with a corresponding increase in total N and % N, P, Ca and Mg. Lime, in the absence of boron, decreased nodule weight. No effect was observe on the variables measured in the study where Mg was added. Boron, in the presence of lime, increased dry matter production, total N and nodule weight. On the other hand, the application of this micronutrient decreased the levels of N, P, K, Ca and Mg in the plant. Zinc also increased dry matter production, total N and nodule weight. Its effect on the % P, % K and % Mg in the plant was negative. Molibdenum in absence of lime increased symbiotic nitrogen fixation by the plant as measured by % and total N. |

Tinaroo (Glycine wightii) em um latossolo vermelho-escuro fase cerrado. O delineamento experimental utilizado foi um fatorial 25 em blocos ao acaso com três repetições. Foram estudadas as seguintes variáveis: peso seco, N total, peso de nódulos e teores de N, P, K, Ca e Mg na parte aérea. Em face dos dados obtidos concluiu-se que a calagem teve um efeito pronunciado no peso seco, N total e nos teores de N, P, Ca e Mg das plantas. O peso dos nódulos diminuiu com a calagem quando não foi aplicado boro. A aplicação de magnésio não afetou qualquer variável estudada. Nos tratamentos com calagem, o boro aumentou a produção de matéria seca, N total e peso de nódulos, tendo diminuído os teores de N, P, K, Ca e Mg na parte aérea. A interação calagem X zinco foi significativa somente no peso seco das plantas e seu teor de P e K. O molibdênio, quando em ausência de calagem, aumentou o N total e percentual nas plantas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFrança, Gonçalo E. deBahia Filho, Antonio F.C.Carvalho, Margarida M. de2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17528Pesquisa Agropecuaria Brasileira; v.8, n.8, 1973: Série Agronomia; 197-202Pesquisa Agropecuária Brasileira; v.8, n.8, 1973: Série Agronomia; 197-2021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17528/11751info:eu-repo/semantics/openAccess2014-04-15T18:50:52Zoai:ojs.seer.sct.embrapa.br:article/17528Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:50:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
