Resumo: | Six field experiments were conducted at the National Rice and Bean Research Center, Goiânia, with the objective of comparing the combined effect of the different practices recommended by research with those utilized by the rice farmers. The treatments included measures recommended to solve some of the principal problems that limit upland rice production. The use of supplementary irrigation significantly increased production, but its economic value needs further studies. Fertilizer application based on soil analysis resulted in higher yields when compared with fertilizer rates commonly used by farmers, even under drought conditions. Hand weed control was superior to the application of the herbicide Butachlor. Seed treatment did not consistently contribute to increased yield which should have occured as a consequence of the reduced incidence of pests and diseases. Cultivar IAC 47 was better adapted for upland conditions than the modern, semidwarf and high tillering cultivars. Better response to new technology was only obtained in years with normal rainfall distribution. |

Os tratamentos incluíram medidas recomendadas para resolver alguns dos principais problemas que limitam a produção de arroz. O uso da irrigação suplementar propiciou produções mais elevadas; entretanto, a adoção dessa prática requer mais estudos de ordem econômica. A adubação, baseada na análise do solo, apresentou maiores produções, em comparação com a feita empiricamente pelo agricultor, mesmo quando ocorreu deficiência hídrica. A prática de capina sempre se mostrou superior ao emprego do herbicida butacloro. O tratamento das sementes não contribuiu de modo efetivo para aumentar as produções, o que deveria ter ocorrido em virtude da redução da incidência das pragas e doenças. Em geral, não houve resposta na produção de grãos para os inseticidas e fungicidas empregados. A cultivar IAC 47 mostrou ser mais adequada às condições de sequeiro do que as modernas, de porte baixo e altamente perfilhadoras. As respostas ao emprego de novas técnicas somente foram obtidas quando aliadas a uma boa distribuição pluviométrica.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Alberto Baêta dosStone, Luis FernandoFageria, Nand KumarPrabhu, Anne SitaramaMah, Marcos Ga ChingAquino, Antonio Renes Lins deAjimura, Goes MatsutaroFilho, Morel Pereira BarbosaZimmermann, Francisco José PfeilstickerCarvalho, José Ruy Porto deOliveira, Aldo Bezerra deFilho, Austrelino Silveira2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15910Pesquisa Agropecuaria Brasileira; v.17, n.6, jun. 1982; 835-845Pesquisa Agropecuária Brasileira; v.17, n.6, jun. 1982; 835-8451678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15910/10003info:eu-repo/semantics/openAccess2014-04-16T13:41:57Zoai:ojs.seer.sct.embrapa.br:article/15910Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T13:41:57Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
