Resumo: High energy sorghum (Sorghum bicolor (L.) Moench) cultivars have been recently developed for grain and biomass production. Whole plant utilization is the target of this concept. The objective of this study was to identify the relationship between the harvest date and biomass yield. Experimental trials were conducted with the cultivar BR 505 in the years 1984/85, 1985/86 and 1986/87 to determine its performance as a high energy crop. High biomass and sugar yields were obtained at the physiological maturity stage of the plants. Sucrose and total sugars of the plant increased continually from the visible spikelet stage to the physiological maturity. However, reducing sugar level showed a fall over the same period. In the years 1984/85 and 1985/86 the total biomass yield was 38.9 and 52.0 t/ha respectively. Late sowing date which occurred in the year 1986/87 and the elimination of the supplementary N fertilization reduced significantly the biomass yield as well as the sugar level in the stalks. Grain production of the complementary N fertilization was not affected significantly.

Moench) com alta capacidade energética têm sido desenvolvidas, com a dupla finalidade de produção de grãos e de colmos com elevado teor de açúcares. O objetivo deste estudo foi identificar a relação entre época de corte e o rendimento em biomassa verde de colmos com alto teor de açúcares. Os experimentos foram conduzidos nos anos agrícolas de 1984/85, 1985/1986 e 1986/87 com a cultivar BR 505, para avaliar sua eficiência energética. Rendimentos altos em biomassa verde e elevados teores de açúcares nos colmos foram obtidos quando a planta atingiu o estágio de maturidade fisiológica. Os teores de açúcares totais e de sacarose na planta aumentaram, continuamente, desde a época de emergência das inflorescências até atingir o estágio de maturidade fisiológica, ao contrário do nível de açúcares redutores. Nos anos agrícolas 1984/85 e 1985/86 o rendimento em massa verde foi de 38,9 e 52,0 t/ha, respectivamente. Já no ano agrícola 1986/87, com o plantio tardio e com a eliminação da adubação nitrogenada de cobertura, enquanto o rendimento da biomassa e o teor de açúcares dos colmos reduziram consideravelmente, a produção de grãos não foi afetada de maneira significativa.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTeixeira, Cyro GonçalvesJardine, José GilbertoNicolella, GilbertoZaroni, Margarida Hoeppner1999-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5405Pesquisa Agropecuaria Brasileira; v.34, n.9, set. 1999; 1601-1606Pesquisa Agropecuária Brasileira; v.34, n.9, set. 1999; 1601-16061678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5405/2597info:eu-repo/semantics/openAccess2010-07-08T19:05:16Zoai:ojs.seer.sct.embrapa.br:article/5405Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-08T19:05:16Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
