| O uso de suplementos concentrados e a adequação proteica nestes suplementos podem ser importantes ferramentas para os sistemas de produção de ovinos em pastagens tropicais. O presente trabalho teve por objetivo avaliar diferentes fontes proteicas no suplemento concentrado de ovinos mantidos em pastagens irrigadas de Tifton 85. Os tratamentos avaliados foram: animais não-suplementados (controle), farelo de soja, ureia e torta de algodão, no suplemento concentrado múltiplo (20% de proteína bruta e 74% de nutrientes digestíveis totais). A quantidade de concentrado fornecida diariamente foi de 0,180 kg animal-1. Foram utilizados 28 ovinos machos castrados, mestiços Santa Inês x sem padrão racial definido, com peso corporal inicial de 28 kg. O período... |

| The objective of this study was to evaluate the effects of the application of different water depths and nitrogen and potassium doses in the quality of Tanzania grass, in the southern of the state of Tocantins. The experiment was conducted on strips of traditional sprinklers, and used, as treatments, a mixture of fertilizer combinations of N and K2O always in the ratio of 1 N:0.8 K2O. This study determined throughout the experiment: plant height (PH), the crude protein (CP) and neutral detergent fiber (NDF). The highest plant height obtained was 132.4 cm, with a fertilizer dose of 691.71 kg ha-1 in the proportion of N:0.8 K2O, in other words, 384.28 kg ha-1 of N and 307.43 kg ha-1 of K2O, and water depth of 80% of the ETc. The highest crude protein content... |

| ABSTRACT In the correct pasture management, nutritional factors such as nitrogen and potassium fertilization play an important role in the forage production and quality. The aim was to evaluate the effects of the application of water levels, nitrogen and potassium doses in the Xaraés grass in the south of the State of Tocantins. For this, Xaraés grass was cultivated in the experimental field of the Federal University of Tocantins, municipality of Gurupi, TO. We used a mixture of fertilizer, combinations of N and K2O following the 1 N: 0.8 K2O ratio. To evaluate the effect of irrigation water levels and combinations of N and K2O doses in Xaraés grass, the plant height, the crude protein content and neutral detergent fiber were determined. The greatest... |
