Resumo: The annual sorghum (Sorghum bicolor L. Moench) grain production potential of eight commercial hybrids and two varieties was evaluated under irrigated conditions in the São Francisco Valley. A double row system spaced 40 cm apart in beds of 70 cm width, with approximatelly 15 plants/m in each row. The hybrids tested were much more productive than the varieties. A gradual decrease in the average yield was obtained from the first harvest to the first and second ratoon cropping, with 9,313, 6,476 and 3,602 kg/ha, respectively. The total average yield from the three harvests reached 19,391 kg/ha which indicates the technical viability of exploring grain sorghum under irrigated conditions.

Moench), sob condições irrigadas no vale do São Francisco. Utilizou-se o sistema de plantio em fileiras duplas espaçadas de 40 cm, em bancadas de 70 cm de largura, com, aproximadamente, quinze plantas por metro linear em cada fileira. Observou-se que os híbridos foram bem mais produtivos do que as variedades. Constatou-se uma diminuição gradativa e uniforme na produção de todos os tratamentos da primeira colheita para a soca e ressoca, com produções médias de 9.313, 6.476 e 3.602 kg/ha, respectivamente. A produção total média dos três cultivos alcançou 19.391 kg/ha, o que demonstra a viabilidade técnica de exploração da cultura na região sob condições irrigadas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAguiar, Paulo Anselmo Andrade2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16579Pesquisa Agropecuaria Brasileira; v.16, n.1, jan. 1981; 117-120Pesquisa Agropecuária Brasileira; v.16, n.1, jan. 1981; 117-1201678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16579/10862info:eu-repo/semantics/openAccess2014-04-15T19:35:55Zoai:ojs.seer.sct.embrapa.br:article/16579Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T19:35:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
