Resumo: The sorghum crop stands out in animal feeding, as this feedstuff can be preserved still fresh in the form of silage. This study was conducted to determine the agronomic characterization and chemical composition of sorghum hybrids in rainfed conditions aiming at silage production. Twenty-five sorghum hybrids were used in a randomized-block experimental design with three replicates. The following variables were evaluated: number of tillers; plant height; percentages of leaf, stem, panicle, grain and dead material; leaf:stem ratio; live:dead material ratio; total fresh matter yield; total dry matter yield; yields of leaf, stem, panicle, grain and dead material (in t ha-1 DM); and chemical composition. Data were analyzed by the Scott-Knott procedure at the 5% significance level. The greatest observed heights were 214.53, 229.00 and 240.07 cm, found in hybrids SF15, SF25 and PROG134IPA, respectively. There was an effect for morphological characterization (P < 0.001), with the best means observed in hybrids 9929030 and 9929026. The highest total fresh matter yields were found in SF15, SF11, 12F042150 (93.95, 82.61 and 79.27 t ha-1, respectively). Adequate dry matter contents for ensiling were observed in hybrids 9929030, 12F042224, 12F042150, FEPAGRO18, FEPAGRO19, FEPAGRO11, SF15, SF25, 1141572, 1141570 and BRS Ponta Negra. In terms of crude protein content, hybrids 9929030, FEPAGRO18, FEPAGRO11, 9929026, 947072, 947252, 12F042226 and BRS Ponta Negra stood out with values between 6.55 and 8.64%. Hybrids 9929030, 12F042224, 12F042150, FEPAGRO19, FEPAGRO11, 1141572 and 1141570 exhibited potential for silage production.

Objetivou-se determinar a caracterização agronômica e composição química entre híbridos de sorgo em condições de sequeiro visando a produção de silagem. Foram utilizados 25 híbridos de sorgo em delineamento em blocos casualizados com três repetições. Avaliou-se número de perfilhos, altura planta, porcentagens de folha, colmo, panícula, grão e material morto, relações de folha:colmo e material vivo:material morto, produtividade total de massa verde e seca e produtividade de folha, colmo, panícula, grãos e material morto em t ha-1 MS e composição química. Os dados foram analisados pelo procedimento Scott-Knott ao nível 5% de significância. Maiores alturas observadas foram de 214,53, 229,00 e 240,07 cm para os híbridos SF15, SF25 e PROG134IPA, respectivamente. Houve efeito na caracterização morfológica (P < 0,001) em que as melhores médias foram observadas nos 9929030 e 9929026. Maior produtividade total de massa verde foi constatada em SF15, SF11, 12F042150 com 93,95, 82,61 e 79,27 t ha-1, respectivamente. Já para teor de matéria seca adequado para ensilagem, foi obtido nos 9929030, 12F042224, 12F042150, FEPAGRO18, FEPAGRO19, FEPAGRO11, SF15, SF25, 1141572, 1141570 e BRS Ponta Negra. Com relação à proteína bruta, destacaram-se 9929030, FEPAGRO18, FEPAGRO11, 9929026, 947072, 947252, 12F042226 e BRS Ponta Negra com teores entre 6,55 a 8,64%. Os híbridos 9929030, 12F042224, 12F042150, FEPAGRO19, FEPAGRO11, 1141572 e 1141570 apresentam potencial para produção de silagem.UEL2020-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3360210.5433/1679-0359.2020v41n2p407Semina: Ciências Agrárias; Vol. 41 No. 2 (2020); 407-420Semina: Ciências Agrárias; v. 41 n. 2 (2020); 407-4201679-03591676-546Xreponame:Semina.
