| The objective of this study was to evaluate the agronomic divergence of 25 sorghum hybrids (Sorghum bicolor L. Moench) in the semiarid region of Paraiba. A randomized block design with three replications was used for evaluation of plant height (PH), total natural matter production (TNMP) and total dry matter production (TDMP) and the percentage of components of DM (panicle, leaf blade, stem and dead matter) of the following hybrids: 866005, 866019, 866033, 866034, 866035, 866036, 866037, 866040, 866041, 866042, 866043, 866044, 870025, 870031, 870035, 870041, 870051, 870067, 870081, 870085, 870095, 1F305, BRS 610, Volumax, and XBS60329. Hybrid 1F305, followed by hybrid 866034, presented the highest average PH. There was a range from 7.679 to 20.948 kg/ha... |

| The objective of this study was to evaluate agronomic characteristics of 32 sorghum cultivars (Sorghum bicolor(L). Moench) in the Brazilian semi-arid region. The experimental design was set up in randomized blocks with three replications. Treatments were the 32 sorghum cultivars. The evaluated variables were: plant height, stem diameter, tiller density, number of green leaves per tiller, average leaf length, dry matter content, fresh matter production and dry matter production (DMP) in kg/ha, and the percentage of the components panicle, leaf blade and stem. To avoid associative effects due to the presence of positive correlation with DMP, the variables plant height, number of plants per hectare and fresh matter production were excluded for being part of... |

| Objetivou-se quantificar o rendimento forrageiro, o percentual de componentes da planta, as características morfométricas e a eficiência do uso da chuva de cinco genótipos de sorgo para silagem no semiárido paraibano. O experimento foi conduzido na Estação Experimental Pendência, no município de Soledade-PB. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, sendo os tratamentos experimentais representados por cinco genótipos de sorgo: Ponta Negra, SF 15 IPA 1011, IPA 2502 e IPA 46742. Não foram observadas diferenças entre os genótipos para a produção de matéria natural e produção de matéria seca e para o percentual de lâmina foliar. Entretanto, para o percentual de colmo foram observados maiores valores (P<0,05)... |

| Objetivou-se com este estudo avaliar o resultado econômico da terminação de ovinos em confinamento, alimentados com silagens de diferentes cultivares de sorgo: 'BRS 810' e 'BRS Ponta Negra' (caráter forrageiro); 'BRS 610' (caráter duplo propósito); e 'BRS 655' e 'BRS 800' (caráter granífero). Utilizaram-se 35 cordeiros, sem padrão racial definido, com idade entre 5 e 7 meses e com peso vivo médio de 17,7±3,7kg. Os animais foram mantidos confinados em gaiolas individuais durante 42 dias, sendo abatidos com peso médio de 26,24kg. Utilizou-se um delineamento inteiramente casualizado, com cinco tratamentos (silagem de diferentes cultivares de sorgo) e sete repetições. A relação volumoso:concentrado foi de 48:52 (com base na MS), para todas as dietas testadas.... |

| This study aimed to evaluate the fermentation characteristics, losses and the chemical composition of two pearl millet genotypes silages submitted to nitrogen fertilization. The experimental design was a completely randomized blocks in a split plot scheme 2x5 (two nitrogen genotypes doses x five doses of nitrogen), with four replicates. Nitrogen doses were 0, 20, 40, 60, 80kg ha-1 and the pearl millet genotypes were the variety ADR300 and the hybrid ADR7010. The hybrid ADR 7010 showed average lactic acid content higher than the variety ADR 300, at all doses of N, recording values ranging from 4.09 to 10.46dag kg-1. There was an interaction between nitrogren doses and genotypes for the neutral detergent fiber, which ranged from 51.81 to 63.63dag kg-1 of dry... |

| This study aimed to assess the fermentation profile, losses and chemical composition of the silages of five sorghum cultivars. A completely randomized design with five replicates was used. The experimental treatments were represented by five sorghum cultivars (Sorghum bicolor (L). Moench): 'BRS Ponta Negra' , 'BRS 610', 'BRS 655', 'BRS 800' and 'BRS 810'. There was variation (P<0.05) for the pH in the cultivars studied, with highest result of pH by 'BRS 610'. The average percentages of lactic acid, acetic acid and propionic acid, differed (P<0.05) among the cultivars, ranging from 32.9 to 59.5, 19.8 to 39.8, and 0.0 to 1.3g kg-1, respectively. The dry matter recovery varied among cultivars (P<0.05), allowing the identification of BRS Ponta Negra,... |
