Resumo: | A greenhouse experiment was carried out to study the interference of phosphorus and calcium with symbiotic nitrogen fixation of two varieties of perennial soybean (Glycine Javanica L.) in soils with manganese toxicity. The same experiment explores the possibility of supplying the high demand for phosphorus and calcium during plant establishment by coating the seed with rockphosphate. The following conclusion were drawn: 1) Seed pelleting with rockphosphate (from Olinda) did not substitute for phosphorus fertilizer but it did increase calcium deficiency symptoms in very young plants. 2) Fertilization with phosphorus increased, significantly, nodule growth and total nitrogen in the plant but had no effect on nodule numbers of the amount of N fixed per unit of nodule weight. These effects were more pronounced with variety SP.1. 3) Calcium applied as gypsum increased nodule size but tended to decrease their number so that there was no significant effect on total nodule weight or nitrogen fixation. The amount of N fixed per unit nodule weight was also unaffected by calcium. 4) Phosphorus and calcium stimulated manganese absorption. The latter increasing translocation of this element from roots to the aerial portion of the plant. 5) In soil with manganese toxicity, the variety SP.1 produced higher nodule weights, more total nitrogen in plants and higher forage yields than did the variety Tinaroo. 6) The variety Tinaroo absorbed more manganese than variety SP.1, without evidencing differences in translocation. 7) Seed coating increased manganese absorption and reduced nodule weight and nitrogen fixation in the variety Tinaroo. The opposite occurred with the variety SP.1. |

(Glycine javanica L.) em solo com toxidez de manganês. No mesmo experimento pesquisou-se a possibilidade de suprir as elevadas demandas de fósforo e cálcio na fase do estabelecimento das plantas pelo revestimento das sementes com fosforita de Olinda ("pellet"). Chegou-se às seguintes conclusões: 1) O revestimento das sementes com fosforita nada adiantou em relação à substituição da adubação fosfatada mas melhorou a deficiência de cálcio das plantas recém-germinadas. 2) Houve efeito altamente significativo da adubação fosfatada sobre o desenvolvimento dos nódulos uma vez formados e sobre a fixação de nitrogênio, não se registrando efeito sobre a eficiência dos mesmos. Os efeitos do fósforo foram mais pronunciados na variedade SP. 1. 3) O cálcio, aplicado em forma de gesso, aumentou o tamanho dos nódulos tendendo a diminuir seu número e não tendo por isto efeito sobre o nitrogênio fixado. A eficiência dos nódulos também não foi afetada. 4) O fósforo e o sulfato de cálcio estimularam a absorção do manganês, e o gesso aumentou ainda a translocação daquele elemento para a parte aérea. 5) Foram confirmadas as diferenças fisiológicas entre as duas variedades usadas, sob os seguintes aspectos: 5.1) Em solo com toxidez de manganês a variedade SP.1 apresentou vantagens sobre a variedade. Tinaroo, no que se refere à nodulação e fixação de N e, como consequência, na produção de forragem. 5.2) . A variedade Tinaroo absorveu mais manganês que a variedade SP.1 não se registrando diferenças na translocação. A absorção do manganês na variedade Tinaroo foi aumentada ainda pelo revestimento da semente, que ao mesmo tempo diminuiu o peso dos nódulos e o N fixado. O contrário aconteceu com a variedade SP.1.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSouto, Sebastião ManhãesDöbereiner, Johanna2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17778Pesquisa Agropecuaria Brasileira; v.4, n.1, 1969: Série Agronomia e Veterinária; 59-66Pesquisa Agropecuária Brasileira; v.4, n.1, 1969: Série Agronomia e Veterinária; 59-661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17778/11928info:eu-repo/semantics/openAccess2014-04-15T18:25:41Zoai:ojs.seer.sct.embrapa.br:article/17778Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:25:41Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
