Resumo: | Sorghum culture highlighted in animal nutrition because it allows its cultivation of green conservation as silage. This study aimed to evaluate the divergence of agronomic and productive characteristics of 32 sorghum cultivars in the semiarid region. The randomized block design with three replications was used. It was evaluated the dry matter percentage (DM), fresh matter production (FMP) and dry matter production (DMP); stem proportion, panicle, and leaf blade in the plant DM; plant height, nº plants ha-1, stem diameter, leaf number, leaves and panicles length; rain use efficiency (RUE) in kg MS ha-1 mm-1, and water accumulation (WA) in kg ha-1 and kg ha-1 mm-1. The data were analyzed using the Scott-Knott procedure at a 5% significance level. The FMP and DMP showed the formation of two distinct groups, which may be crucial in choosing a more productive cultivar. Moreover, cultivar 17 stood out for presenting high leaf blade participation while cultivars 9, 19, 23, 24, and 32 in panicle participation in DM, which is considered nutritionally better due to higher digestibility than the stem. Besides, for the RUE and WA, two distinct groups were also formed, which can be great to determine cultivars that have higher xerophilic potential, and thus use them for the production of silage in semi-arid conditions. Experimental cultivars showed greater results than those commercials. Studies that evaluate the animal performance of cultivars (3, 6, 9, 17, 19, and 31), could be conducted to prove their nutritional values since these cultivars stood out for presenting interesting productive characteristics. |

El objetivo fue evaluar la divergencia de las características agronómicas y productivas de 32 cultivares de sorgo en la región semiárida. El diseño adoptado fue en bloques al azar con tres repeticiones. Se evaluó: concentración de materia seca (DM), producción verde (FMP) y seca (DMP) en kg ha-1; proporción de tallo, panícula y lámina de la hoja en la planta DM; altura de la planta, número de plantas ha-1, diámetro del tallo, número de hojas, tamaño de hojas y panículas; eficiencia del uso de lluvia (RUE) en kg MS ha-1 mm-1 y acumulación de agua (WA) en kg ha-1 y kg ha-1 mm-1. Los datos se analizaron mediante el procedimiento de Scott-Knott a un nivel de significación del 5%. El FMP y el DMP mostraron la formación de dos grupos distintos, que pueden ser cruciales para elegir un cultivar más productivo. El cultivar 17 se destacó por presentar una gran proporción de la lámina de la hoja y los cultivares 9, 19, 23, 24 y 32 en la participación de la panícula en la DM, que son nutricionalmente importantes debido a la mayor digestibilidad que el tallo. Para los RUE y WA también se formaron dos grupos distintos, que pueden ser importantes para determinar cultivares que tengan un potencial xerofílico superior y, por lo tanto, usarlos para la producción de ensilaje en condiciones semiáridas. Se pueden realizar investigaciones que evalúen el rendimiento de los animales con los cultivares 3, 6, 9, 17, 19 y 31 para probar el valor nutricional de estos cultivos, ya que se destacaron por presentar interesantes características productivas y de adaptabilidad.A cultura do sorgo se destaca na nutrição animal por possibilitar seu cultivo para conservação verde como silagem. Objetivou-se avaliar a divergência das características agronômicas e produtivas de 32 cultivares de sorgo na região Semiárida. O delineamento adotado foi em blocos casualizados com três repetições. Avaliou-se: concentração de matéria seca (DM), produção de matéria verde (FMP) e seca (DMP) em kg ha-1; proporção de colmo, panícula e lâmina foliar na MS da planta; altura da planta, número de plantas ha-1, diâmetro de colmo, número de folhas, tamanho de folhas e de panículas; eficiência do uso da chuva (RUE) em kg MS ha-1 mm-1 e acúmulo de água (WA) em kg ha-1 e kg ha-1 mm-1. Os dados foram analisados pelo procedimento Scott-Knott ao nível 5% de significância. As FMP e DMP apresentaram formação de dois grupos distintos, que podem ser cruciais na escolha de uma cultivar mais produtiva. A cultivar 17 se destacou por apresentar uma alta participação de lâmina foliar e as cultivares 9, 19, 23, 24 e 32 na participação de panícula na DM, que são nutricionalmente importante devido à maior digestibilidade que o colmo. Para RUE e WA também foram formados dois grupos distintos, que podem ser importantes para determinar cultivares que apresentem potencial xerófilo superior, e assim utilizá-los para produção de silagem em condição semiárida. Pesquisas que avaliem o desempenho animal com as cultivares 3, 6, 9, 17, 19 e 31 podem ser conduzidos para comprovar o valor nutritivo dessas culturas, já que estas se destacaram por apresentar características produtivas e de adaptabilidade interessantes.Research, Society and Development2020-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/490110.33448/rsd-v9i7.4901Research, Society and Development; Vol. 9 No. 7; e883974901Research, Society and Development; Vol. 9 Núm. 7; e883974901Research, Society and Development; v. 9 n. 7; e8839749012525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/4901/4311Copyright (c) 2020 Alexandre Fernandes Perazzo, Edson Mauro Santos, Juliana Silva de Oliveira, Gabriel Ferreira de Lima Cruz, Rosângela Claurenia da Silva Ramos, Gildenia Araújo Pereira, Ricardo Martins Araujo Pinho, Fleming Sena Camposinfo:eu-repo/semantics/openAccessPerazzo, Alexandre FernandesSantos, Edson MauroOliveira, Juliana Silva deCruz, Gabriel Ferreira de LimaRamos, Rosângela Claurenia da SilvaPereira, Gildenia AraújoPinho, Ricardo Martins AraujoCampos, Fleming Sena2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4901Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:36.298358Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
