| Busca alternativas de controle da cigarrinha-das-pastagens, selecionando-se gramineas resistentes a praga em referencia. O experimento foi conduzido de 30 especies de gramineas forrageira distribuidas em blocos ao acaso com 4 repeticoes. As avaliacoes foram feitas atraves de amostragens quinzenais durante o periodo de 1984-86. As gramineas Andropogon gayanus, cv. Planaltina(BRA-000019), Brachiaria brizantha, cv. Marandu (BRA-OOO591), Panicum maximum, cv. Tobiata (BRA-001511), Paspalum secans (BRA-003778) e Paspalum coryphaeum (BRA-003760), mostraram-se resistentes a cigarrinha-das-pastagens. |

| A bovinocultura de corte, principal atividade economica da sub-regiao da Nhecolandia, do Pantanal, devido, principalmente, a problemas nutricionais, apresenta baixos indices de produtividade. A alimentacao dos bovinos e constituida de pastagens nativas, geralmente de produtividade ou valor nutritivo baixos e de baixa disponiblidade nos meses de cheia. Face a esta situacao, o CPA-Pantanal, entre 1980 e 1985, realizou um experimento de introducao e avaliacao da forrageira em area de "cordilheira" desmatada com o objetivo de identificar gramineas e leguminosas adaptaveis as suas condicoes ecologicas. As forrageiras (43 gramineas e 123 leguminosas) foram plantadas em parcelas de 1,5 x 3,0 m. Foram utilizadas duas parcelas, por local, para cada especie, uma com... |

| O Pantanal ocupa aproximadamente 4,2% do território nacional, segundo o Plano de Conservação da Bacia do Alto Paraguai - PCBAP, sendo reconhecidamente um dos Biomas mais importantes do Planeta, quer pela sua biodiversidade enquanto produtividade natural. A vegetação do Pantanal recebeu influência de outras regiões, como Chaco, Cerrado, Floresta Amazônica e Mata Atlântica. A pecuária de corte, em regime extensivo, é a principal atividade econômica da região. O fogo é uma ferramenta de manejo bastante utilizada no Pantanal, com o intuito de eliminar principalmente as gramíneas não consumidas pelos bovinos (capins duros e secos), plantas invasoras e também pequenos arbustos distribuídos nos campos. Sabe-se que o fogo acidental é prejudicial para a fauna e a... |

| Spatial and temporal patterns of aboveground biomass and nutritive value of rangeland species with respect to the influence of grazing and soil moisture were investigated. The research was conducted during two years at the Tomagh Research Station, near Sanjawi, Ziarat District, Balochistan, Pakistan. This area is protected from grazing since 1998; however, some of the area is open for grazing. Tree sites were selected for research purposes: a protected plain, a protected hilly, and an unprotected plain grazed area. Sampling was carried out during the spring, summer and autumn seasons. Results revealed that soil moisture was greater at the protected than unprotected sites. The aboveground plant biomass was 66% to 76% lower at unprotected than protected... |

| ABSTRACT The present study was conducted to assess antifungal potential of the allelopathic grass Cenchrus pennisetiformis Hochst. & Steud. against the fungal plant pathogen Fusarium oxysporum f. sp. lycopersici (cause of tomato wilt disease) under chromium stress. Laboratory experiments were performed in 10 mL volume glass test tubes each containing 1.0 mL of malt extract broth with seven concentrations (0, 50, 100, 150, 200, 250, 300 and 350 ppm) of each of Cr(III) and Cr(VI), and two concentrations (5% and 6%) of methanolic leaf, stem or root extract of C. pennisetiformis. A metal + weed extract amended medium was inoculated with the pathogen and incubated for 7 days at 25 C. Different concentrations of Cr(III) and Cr(VI) proved equally inhibitory... |

| The present study aimed to assess the effect of supplementation on the performance of F1 (Boer × females of no defined breed) goats finished in native pasture. The experiment was conducted at the Universidade Federal de Campina Grande, Patos Campus, Paraíba, Brazil, with twenty-four 120-day-old non-castrated F1 (Boer × NDB) male goats, with a 15.52 kg live weight (LW). Animals were distributed in four levels of supplementation (0.0; 0.5; 1.0; 1.5% of body) and six replicates. In order to perform the evaluation of dry matter availability, the herbaceous vegetation was divided into grass and herbaceous dicotyledon and evaluated at the beginning (5/28/2007), in the middle (7/9/2007) and at the end (8/6/2007) of the experiment. In the beginning of the... |

| Soil organic matter of a humic Oxisol has been characterized by analyzing litter and soil lipid composition under vegetal covers (coffee, pasture and fragment of native forest). Soil and litter samples were collected from each site at two depths (0-10 and 60-100 cm). Lipid composition was determined by gas chromatography-mass spectrometry (CG-MS). In the solvent extracts of the soil lipids, even-numbered n-alkanoic acids in the range of C16-C32 indicate a soil organic matter input from higher plant waxes. The major compound classes in both the soil and the litter included saturated n-alkanoic acids, with average values in the total spectrum of 58 and 53%, respectively Clear differences in lipid composition were found between the topsoil and subsurface.... |
