Resumo: | The effect of adding boron and molybdenum to seed coating of beans (Phaseolus vulgaris L.) under field conditions at Instituto de Pesquisas e Experimentação Agropecuárias do Centro-Sul, Rio de Janeiro, is reported. Specifically studied were effects on nodulation, nitrogen fixation and seed production. Four coating types were used: a) calcium carbonate; b) rock phosphate; c) 50% rock phosphate and 50% calcium carbonate; d) 50% rock phosphate, 25% calcium carbonate and 25% magnesium carbonate. Boron and molybdenum were added individually and together to each. Among the coatings, plain rock phosphate was significantly lower for dry weight of nodules, nitrogen fixation and bean production. Neither micronutrient increased nodulation although the addition of molybdenum to rock phosphate increased dry nodular weight. Boron significantly increased total nitrogen, plant growth (at flowering) and bean production. When molybdenum as well as boron was added, nitrogen percentage, total nitrogen and nodular weight were significantly increased only when rock phosphate was also present. When both micronutrients were used with rock phosphate and calcium carbonate there was a significant increase in bean production. |

Effect of boron and molybdenum applied to seed coatings of beans (Phaseolus vulgaris)Efeito do boro e do molibdênio aplicados a diferentes revestimentos da semente de feijão (Phaseolus vulgaris)The effect of adding boron and molybdenum to seed coating of beans (Phaseolus vulgaris L.) under field conditions at Instituto de Pesquisas e Experimentação Agropecuárias do Centro-Sul, Rio de Janeiro, is reported.

Adotou-se um ensaio fatorial 4 x 2 x 2 no delineamento experimental de quase-quadrado latino 8 x 8, com confundimento das interações de segunda ordem. Foram testados quatro diferentes revestimentos: a) com carbonato de cálcio; b) com fosforita; c) com 50% de fosforita + 50% de carbonato de cálcio; d) com 50% de fosforita + 25% de carbonato de cálcio + 25% de carbonato de magnésio. O boro e o molibdênio foram adicionados a cada revestimento isoladamente e combinados. Utilizou-se um solo "gray" hidromórfico da série Ecologia, na sede do Instituto de Pesquisas e Experimentação Agropecuárias do Centro-Sul (IPEACS). Comparando-se os revestimentos entre si, notamos que aquêles com carbonato de cálcio, com fosforita + carbonato de cálcio e com fosforita + carbonato de cálcio + carbonato de magnésio apresentaram-se com efeitos significativamente superiores aos de fosforita para pêso sêco dos nódulos, fixação simbiótica do nitrogénio e produção do feijoeiro. Os dois micronutrientes estudados não influenciaram na nodulação; no entanto, no revestimento com fosforita, o molibdênio aumentou a massa nodular. O boro aumentou significativamente o nitrogênio total, o desenvolvimento das plantas (na época da floração) e a produção; o molibdênio, quando na presença do boro, aumentou com significância estatística o N percentual e N total, somente quando adicionado ao revestimento com fosforita. Ainda o molibdênio, na presença do boro, provocou um significativo aumento na produção de feijão, quando se utilizou o revestimento de fosforita + carbonato de cálcio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRuschel, Alaides PuppinRocha, Antonio Carlos de MesquitaPenteado, Alberto de Figueiredo2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17596Pesquisa Agropecuaria Brasileira; v.5, n.1, 1970: Série Agronomia e Veterinária; 49-52Pesquisa Agropecuária Brasileira; v.5, n.1, 1970: Série Agronomia e Veterinária; 49-521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17596/11815info:eu-repo/semantics/openAccess2014-04-15T18:30:22Zoai:ojs.seer.sct.embrapa.br:article/17596Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:30:22Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
