Resumo: The growth patterns of four cultivars of pearl millet (Pennisetum glaucum (L.) R. Brown), and their relationships with grain yield were evaluated through plant growth analysis. In a field experiment in Haplaquult soil, the biomass of cultivars BN-2 and IAPAR (Brazilian cultivars for forage production), Guerguera and HKP (African cultivars for grain yield) was sampled 11 times. Brazilian cultivars presented earlier flowering and higher shoot dry matter in the beginning of the growth cycle, but African cultivars were superior after flowering. There was no significant difference among cultivars for N concentration of tissues and grains. Brazilian cultivars produced double number of panicles, and a more intense tillering. African cultivars presented higher grain yield than Brazilian cultivars (403 versus 268 g m-2), due to 1,000-grain weight, and panicle length almost twice greater. The inferior productivity of forage cultivars was in part due to the low planting density used.

R. Brown) e suas relações com a produção de grãos. Em experimento de campo em um Planossolo, foram efetuadas 11 amostragens semanais de biomassa nas cultivares BN-2 e IAPAR (brasileiras, forrageiras), e Guerguera e HKP (africanas, graníferas). As cultivares brasileiras tiveram floração mais precoce e maior biomassa da parte aérea no início do ciclo, e foram superadas pelas africanas após a floração. Não houve diferença significativa entre cultivares na concentração de N nos tecidos e grãos. As cultivares brasileiras produziram o dobro de panículas e maior perfilhamento. As cultivares africanas tiveram maior produção de grãos que as brasileiras (403 contra 268 g m-2), uma vez que o comprimento de suas panículas e a massa de mil grãos eram cerca de duas vezes superiores em relação às brasileiras. A inferioridade produtiva das cultivares forrageiras foi atribuída, em parte, à baixa densidade de plantio utilizada.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGeraldo, JoséRossiello, Roberto Oscar PereyraAraújo, Adelson PauloPimentel, Carlos2000-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5904Pesquisa Agropecuaria Brasileira; v.35, n.7, jul. 2000; 1367-1376Pesquisa Agropecuária Brasileira; v.35, n.7, jul. 2000; 1367-13761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5904/3008info:eu-repo/semantics/openAccess2014-08-19T16:22:58Zoai:ojs.seer.sct.embrapa.br:article/5904Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-19T16:22:58Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
