- Agronomic traits and nutritional value of forage sorghum genotypes Luciana Oliva Barbosa Lima Daniel Ananias de Assis Pires Marielly Maria Almeida Moura José Avelino Santos Rodrigues Daniella Cangussú Tolentino Maria Celuta Machado Viana Agrociencias Hybrids Productivity Chemical composition This study aimed to evaluate the agronomic performance of 24 sorghum genotypes in four Brazilian regions and the chemical characteristics of genotypes grown in Sete Lagoas, state of Minas Gerais. Genotypes BRS655 and 12F37005 had higher average production of green matter (> 44 ton ha-1) and dry matter (> 17 ton ha-1), respectively. Genotypes 12F38019, 12F40019, 12F37005, 12F37043 and Volumax took more days to flower in three of the four municipalities (75-90 days). Genotypes 12F38006, 12F40006 and 12F37016 were taller (> 2 m). Values of dry matter, crude protein and neutral detergent fiber ranged from 37.15 to 50.13; 5.51 to 10.28 and 43.57 to 65.69%, respectively. The genotypes were not different regarding acid detergent fiber content, with mean value of 34.83%. Genotypes 12F38019, 12F37016, 12F39005, 12F39019, 12F37007, 12F37014, 12F39014 and BRS 655 showed the best values of dry matter digestibility (64.31 to 74.20%) and crude protein content (8.33 to 10.28%). Among them, 12F139014 exhibited the lowest lignin content (3.32%), suggesting less effect of this fraction on digestibility. Genotype 12F39014 is the most suitable for cultivation, as it presented the best nutritional value and good dry matter production in the four municipalities. 2017 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303149707002 https://www.redalyc.org/journal/3031/303149707002/ https://www.redalyc.org/journal/3031/303149707002/html/ https://www.redalyc.org/journal/3031/303149707002/303149707002.epub https://www.redalyc.org/journal/3031/303149707002/movil en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
