| The objective of this study was to assess agronomic characteristics and nutritional values of silages of millet genotypes. Planting was done in randomized blocks, with five replicates per genotype. Green matter yield for genotypes ADR 500 and CMS 01 was higher and similar to each other, with 40.16 and 41.36 t ha (p > 0.05). There was no significant difference for dry matter yield, with the mean being 9.93 t ha (p > 0.05). The silages were similar (p > 0.05) as to pH, Aw and N-NH3/TN, presenting values of 3.92, 0.97 and 7.64%, respectively. There were no significant differences (p > 0.05) concerning the bromatological composition of the silages of the different genotypes, with a mean of 30.74% of dry matter, 10.21% for crude protein and 58.69%... |

| O desempenho agronômico de Panicum maximum cv. Tobiatã, em cultivo puro e consorciado com cinco leguminosas forrageiras tropicais (Desmodium ovalifolium CIAT-350, Centrosema acutifolium CIAT-5277 e CIAT-5112, C. pubescens CIAT-438 e Pueraria phaseoloides CIAT-9900), foi avaliado em ensaio conduzido em Ouro Preto d'Oeste, Rondônia. As consorciações foram mais eficientes na produção de forragem que a gramínea em cultivo puro. O maior rendimento de matéria seca foi registrado na consorciação com C. acutifolium CIAT-5277, o qual não diferiu (P > 0,05) do verificado na mistura com P. phaseoloides. Os teores de proteína bruta da gramínea consorciada foram superiores aos obtidos em seu cultivo isolado. As leguminosas que fixaram e transferiram as maiores... |

| Con el objetivo de cuantificar las diferencias en el rendimiento anual y estacional de forraje y la velocidad de crecimiento de dos gramíneas y una leguminosa en función al manejo estacional de la frecuencia de pastoreo, se realizó el presente estudio en el campo experimental del Colegio de Postgraduados, en Montecillo, Texcoco, Estado de México, en una pradera asociada en su segundo año de establecimiento. Se evalúo el rendimiento de forraje, altura de planta (cm), radiación interceptada (RI, %) y composición botánica del forraje cosechado (% y kg MS), dinámica de rebrote, tasa de aparición, tasa de muerte y tasa de sobrevivencia de tallos (DPT, TAT, TMT, TST). Los tratamientos fueron las asociaciones 100:00:00, 00:100:00, 20:40:40, 00:50:50, 40:20:40,... |

| Abstract The elephant grass (Pennisetum purpureum) is a tropical perennial forage plant with high biomass production that adapts to various soil and climatic conditions in Brazil. Stability is defined as the consistency in performance of genotypes in different environments. The aim of the present study was to estimate stability parameters by the Eberhart and Russel method, and to select elephant grass genotypes with forage production stability and high-yield in Campos dos Goytacazes, RJ, Brazil. Five harvests were made for evaluation in two years. The experimental design was arranged as randomized blocks design, with 80 treatments and two replicates. After the individual analysis of variance for dry matter yield, a combined split-plot analysis was... |

| El presente estudio se realizó de noviembre de 2005 a octubre de 2006, en Isla, Veracruz con clima cálido subhúmedo,. El objetivo fue determinar el rendimiento de forraje, tasa de crecimiento (TC), componentes morfológicos (CM, conformados por hoja, tallo y material muerto), composición botánica (CB), peso por tallo (PT), densidad y dinámica de aparición y muerte de tallos, de tres gramíneas en monocultivo y asociadas con la leguminosa Arachis pintoi. Se establecieron parcelas de 10 x 12 m de B. dictyoneura, B. brizantha cv. Toledo y el híbrido B. ruziziensis x B. brizantha cv. Mulato en monocultivo y asociados con A. pintoi y se pastorearon con ganado bovino cada 30 días. Los tratamientos se distribuyeron en un diseño de bloques completos al azar con... |

| Dry matter yield and chemical composition of forage grasses harvested from an area degraded by urban solid waste deposits were evaluated. A split-plot scheme in a randomized block design with four replicates was used, with five grasses in the plots and three harvests in the subplots. The mineral content and extraction and heavy metal concentration were evaluated in the second cut, using a randomized block design with five grasses and four replicates. The grasses were Brachiaria decumbens cv. Basilisk, Brachiaria ruziziensis, Brachiaria brizantha cv. Marandu and cv. Xaraés, and Panicum maximum cv. Tanzânia, cut at 42 days of regrowth. The dry matter yield per cut reached 1,480 kg ha-1; the minimum crude protein content was 9.5% and the average neutral... |

| Red clover (Trifolium pratense L.) is a valuable forage legume grown alone or in mixture with grasses in temperate regions of the world. Red clover is adapted to a wide range of soil types, pH levels, environmental and management conditions. However, the main limitation of this species is the lack of persistence related to the high mortality of plants. In Chile the main biotic factor affecting survival of plants is the root borer Hylastinus obscurus (Marsham) (Coleóptera; Scolytidae). In 1989, a red clover (T. pratense L.) breeding program was started at Carillanca Research Center of the Institute of Agricultural Research (INIA), Chile, with the main objectives of improving the survival of plants, forage yield and persistence. In 2002 a research line to... |

| ABSTRACT This study investigated the residual effects of pig slurry (PS) applied to common carpet grass pasture (Axonopus affinis) for two years (September 2008-March 2010) on dry matter yield and forage-nitrogen uptake from October 2010-May 2011. A field experiment was conducted in a randomized complete block design with four replications. The treatments were 102, 204, 306, 408, and 510 m3 ha-1 pig slurry applied for two years; one mineral nitrogen rate (1,250 kg ha-1 ammonium nitrate) for two years; and no nitrogen fertilization (control). The pasture was cut at intervals of 48, 34, 43 and 69 days, which corresponded to 266, 300, 343, and 412 days after the last fertilizer application, respectively. Dry matter yield increased by 398 kg ha-1 for each 100... |

| O objetivo do estudo foi avaliar os efeitos da adubação nitrogenada e da irrigação por aspersão no crescimento e na produção de massa seca (MS) da aveia preta (Avena strigosa, Schreb). Foram avaliadas quatro doses de nitrogênio (0, 50, 100 e 150 kg de N ha-1) e também a presença ou ausência de irrigação. Foram determinadas as seguintes variáveis: altura de planta, produção de massa seca, taxa de crescimento e o teor de MS. Quando irrigada, a altura da planta foi maior, refletindo maior produção de massa seca. Na área de sequeiro, o teor de MS foi superior (24,7%) ao da área irrigada (18,7%). Quanto à adubação nitrogenada, houve resposta somente para altura de planta, com comportamento linear, quando da utilização de irrigação. Os efeitos da irrigação foram... |
