Leguminous shrubby species Tephrosia vogelii, Tephrosia sinapou and Crotalaria grahamiana are little known at Brazil, and as well as Cajanus cajan (pigeon pea), show potential for green manuring. Two experiments were conducted at Field conditions: the first one aimed to evaluate the growth of Tephrosia vogelii during 360 days, measuring its phenological characteristics and its agronomic performance as green manure. The second one aimed to evaluate the agronomic performance of Tephrosia vogelii, Tephrosia sinapou, Crotalaria grahamiana and Cajanus cajan. The first experiment was conducted in 2010, at Agroecological Farm, and the second one was conducted between October of 2012 and May of 2013, at Experimental Field of Embrapa Agrobiology, both placed at Serop?dica, Fluminense Lowland. At the first one, the experimental design was of randomized blocks, with four replications. The treatments consisted of 12 mensal samplings, with the evaluations of: plants height, stalk diameter, leaf area, amount of fresh and dry matter in different plant parts, nitrogen content and total amount in the shoot. At the second experiment, it was adopted the experimental design of randomized blocks, with four replications, to evaluate the agronomic performance of the four leguminous species, in relation to plants growth. The evaluated plant parameters were: plants height, stalk diameter, amount of fresh and dry matter, nutrient contents and amounts of macronutrients in the shoot, amount of litter deposited by the evaluated species, and weeds control. In the first experiment, 12 months after sowing Tephrosia vogelii, its plants presented 200 cm of height, 11.2 Mg ha-1 of shoot dry matter, with a ratio stalk/leaf 4, besides a total amount of 192 kg ha-1 of N, in the shoot. In the second experiment, at 210 days after sowing, the evaluated species presented mean values of 180 cm of height, 9.7 Mg ha-1 of shoot dry matter and e 151 kg ha-1 of N. Cajanus cajan deposited around 4.8 Mg ha-1 of dry matter of litter, and Tephrosia vogelii promoted lower suppression of weeds. Both evaluated species of Tephrosia and Crotalaria grahamiana presented desirable characteristics for green manuring, similarly to Cajanus cajan, at conditions of climate and soil of Fluminense Lowland. / A aduba??o verde com esp?cies leguminosas ? uma t?cnica que possibilita melhorias nas caracter?sticas do solo, conservando-o e reduzindo a necessidade de ingresso de nitrog?nio sint?tico industrial ?s unidades de produ??o. As esp?cies leguminosas arbustivas Tephrosia vogelii, Tephrosia sinapou e Crotalaria grahamiana s?o pouco conhecidas no Brasil, e assim como o Cajanus cajan (guandu), apresentam potencial para aduba??o verde. Foram conduzidos dois trabalhos experimentais sob condi??es de campo: o primeiro trabalho teve como objetivo avaliar o crescimento de Tephrosia vogelii ao longo de 360 dias, para aferir suas caracter?sticas fenol?gicas e o seu potencial agron?mico como adubo verde. J? o segundo experimento objetivou avaliar o desempenho agron?mico desta esp?cie e de Tephrosia sinapou, Crotalaria grahamiana e Cajanus cajan. O primeiro experimento foi conduzido no ano de 2010 na Fazendinha Agroecol?gica do Km 47 e o segundo foi conduzido entre outubro de 2012 e maio de 2013, no Campo Experimental da Embrapa Agrobiologia, ambos localizados em Serop?dica, Baixada Fluminense. No primeiro, o delineamento experimental adotado foi de blocos casualisados, com quatro repeti??es. Os tratamentos foram formados de 12 coletas mensais, em que se avaliou: a altura das plantas, o di?metro do caule, ?rea foliar, quantidade de mat?ria fresca e seca em diferentes partes das plantas, teor e quantidade de nitrog?nio (N) na parte a?rea das plantas. No segundo experimento foi adotado um delineamento experimental de blocos casualisados com quatro repeti??es, avaliando-se o desempenho das quatro esp?cies quanto ao crescimento das plantas, tendo como par?metros a altura e o di?metro do caule, a quantidade acumulada de mat?ria seca a?rea, os teores e acumula??o de macronutrientes na parte a?rea, a quantidade de serrapilheira depositada pelas esp?cies e a capacidade de supress?o de esp?cies de ocorr?ncia espont?nea. No primeiro experimento, ao final de 12 meses ap?s a semeadura as plantas de Tephrosia vogelii apresentaram 200 cm de altura, 11,2 Mg ha-1 de mat?ria seca a?rea com uma rela??o caule/folha 4, al?m de uma acumula??o total de N na parte a?rea de 192 kg ha-1. No segundo experimento, aos 210 dias ap?s a semeadura, as esp?cies apresentaram, em valores m?dios, 180 cm de altura, 9,7 Mg ha-1 de mat?ria seca a?rea e 151 kg ha-1 de N. Destaca-se que Cajanus cajan depositou cerca de 4,8 Mg ha-1 de mat?ria seca de serrapilheira, e sob a copa de Tephrosia vogelii observou-se menor controle da ocorr?ncia de esp?cies da vegeta??o espont?nea. Conclui-se que as duas esp?cies do g?nero Tephrosia e Crotalaria grahamiana estudadas apresentaram caracter?sticas desej?veis para inclus?o como adubos verdes, compar?veis a Cajanus cajan, quando avaliadas nas condi??es edafoclim?ticas da Baixada Fluminense.

The experiment was carried out at the Cabral's Haras, farm located in Rio Claro, Rio de Janeiro. Sixteen Mangalarga Marchador foals were used in a completely randomized designwith two treatments and eight repetitions (animals). The treatments were: Treatment I - suplly the FOS once a day orally; Treatment II (control) - the animals received aqueous solution, orally, without FOS additive. The trial period was 75 days of duration, starting supplementation at birth. From birth to the 30th day, daily stool samples were collected directly from rectum. The 30th day onwards, samples were collected every 4 days until the 75th day of age. Immediately after the faeces samples the consistency and its color was written down in a collection form . The pH was mensured from samples previously diluted with equal amounts of distilled water using a digital potentiometer. For chemical analysis the samples were homogenized in weekly composite samples and it was performed chemical analyzes In the performance parameters foals were weighed and it was performed morphometric measurements of height and perimeter. The results were submitted to analysis of variance in a split plot scheme and means were compared by the Student Newman Keuls test, at5% probability. The values of fecal characteristics were compared using the Wilcoxon test in the analysis of the treatment and compared by Kruskal-Wallis test in the analysis of the collection times. There were no significant effects (p <0.05) of supplementation and interaction age versus supplementation for all variables. The average daily gain weight was 0.63 kg during the trial period. The morphometric variables showed average growth of 17.8, 18.7, and 27.5 cm in height at the withers, hip height, body length and chest girth, respectively, from birth to 75 days old. Growth percentage of 31.1, 53.8, 15.6, 22.4, 12 and 12.3% were observed for height and width of the side, the empty substernal height, forearm girth, knee girth and shin girth, respectively . The use of prebiotic fructooligosaccharide did not affect the faecal pH, with average values of 7.22. There was no significant difference (P <0.05) in the physical and chemical characteristics of the stool. The use of prebiotic fructooligosaccharides does not influence the performance of newborn foals to 75 days of age. Further investigation should be conducted to evaluate the responses obtained through fecal parameters and their relationship as an indicator of gastrointestinal health. It prove to be safe in the dose used, it does not promote diarrhea or other gastrointestinal disorders in infants foals. / O objetivo desse estudo foi avaliar os efeitos do prebi?tico Frutooligossacar?deo (FOS) no desempenho dos potros lactentes bem como no pH fecal e nas caracter?sticas f?sicas e qu?micas das fezes dos potros. O experimento foi realizado no Haras do Cabral em Rio Claro, RJ. Foram utilizados 16 potros Mangalarga Marchador em delineamento experimental inteiramente casualizado, com dois tratamentos e oito repeti??es (animais). Tratamento I - fornecimento uma vez ao dia, via oral, do aditivo FOS e o Tratamento II (controle) ? os animais recebiam solu??o aquosa, via oral, sem o aditivo FOS. O per?odo experimental foi de 75 dias, iniciando a suplementa??o ao nascimento. Amostras di?rias de fezes foram coletadas diretamente do reto do nascimento at? o 30o dia de idade. Do 30o dia em diante, as coletas ocorreram a cada 4 dias, at? os 75o dia de idade. Imediatamente ap?s a coleta anotou-se em uma ficha de coleta a consist?ncia e colora??o das amostras. O pH foi avaliado a partir das amostras previamente dilu?das em iguais quantidades de ?gua destilada atrav?s de um potenci?metro digital. Para an?lises qu?micas as amostras foram homogeneizadas em amostras compostas semanais e realizadas an?lises bromatol?gicas. O desempenho dos potros foi avaliado atrav?s do peso vivo e por meio de medidas morfom?tricas lineares e de per?metros. Os resultados foram submetidos ? an?lise de vari?ncia em esquema de parcelas subdivididas e, as m?dias comparadas pelo teste Student Newman Keuls, a 5% de probabilidade. Os valores da caracteriza??o fecal foram comparados pelo teste de Wilcoxon na an?lise entre os tratamentos e, comparados pelo teste de Kruskal-Wallis na an?lise entre os tempos de coleta. N?o foram observados efeitos significativos (p<0,05) na suplementa??o e intera??o idade versus suplementa??o para todas as vari?veis analisadas. O ganho de peso m?dio di?rio foi de 0,63 kg durante o per?odo experimental. As vari?veis morfom?tricas apresentaram crescimento m?dios de 17,8, 18,7, e 27,5 cm para altura da cernelha, altura da garupa, comprimento do corpo e per?metro tor?cico, respectivamente, do nascimento aos 75 dias de idade. Percentuais de crescimento m?dio de 31,1, 53,8, 15,6, 22,4, 12 e 12,3% foram observados para altura e largura do costado, altura do vazio subesternal, per?metros do antebra?o, joelho e canela, respectivamente. O uso do prebi?tico frutooligossacar?deo n?o influenciou no pH fecal, apresentando valores m?dios de 7,22. N?o houve diferen?a significativa (P<0,05) nas caracter?sticas f?sicas e qu?micas das fezes. O uso do prebi?tico frutooligossacar?deo n?o influencia no desempenho de potros lactentes do nascimento aos 75 dias de idade. Maiores investiga??es devem ser realizadas para avaliar as respostas obtidas atrav?s de par?metros fecais e sua rela??o como indicador da sa?de gastrointestinal. A dose utilizada de frutooligossacar?deo n?o promove diarr?ias e dist?rbios gastrointestinais em potros lactentes.

Brazilian Apiculture is currently facing some obstacles to produce wooden hives. Regarding the similar physical properties within the wood, the hives made of cement-vermiculite mortar (CVM) have been tested in order to find out if it shows also similar biological responses to the wooden hives. This study took place in a tropical region ((22?45?28"S, 43?41?05"W), during eight months. Standard Langstroth hives (n=20) were built, and used in an apiary containing Africanized honeybees colonies from equal strength (one super) and queen line. The CVM boxes and colonies were compared with control one (wooden made) in a completely randomized design, with two factors (beginning and end of the study, with and without bees) and 5 repetitions/treatment, which were used in order to test the colony performance patterns: thermal control, flight activity, area of wax comb production and storage of food, weight of the super, honey collected and its chemical analysis. The standard CVM hive (2 supers) weights about 21.66 kg and its cost requirement (US$15.19) was 28.50% cheaper than the wooden hives cost. There were no significant differences between the hives performance. The honey quality sampled in both types of material followed the pattern of the schedule chemical analysis. Although the experiment time was restricted, the results allow us to recommend this new material (CVM) to small or poor beekeepers, to regions that need wood extraction prevention and to tropical regions. For it cannot be transported, the CVM hives must not be used for migratory activity. Hives made of cement-vermiculite mortar have been studied for two years now, and more time is needed to further observations. / A vermiculita expandida ? um material isolante e muito utilizada pela engenharia. Nesta pesquisa, tendo como proposta a constru??o de caixas de abelhas com argamassa cimento-vermiculita (ACV), testou-se se este material apresenta respostas f?sicas e biol?gicas semelhantes ?s caixas constru?das de madeira. Esse estudo foi realizado em uma regi?o tropical (22?45?28"S, 43?41?05"W) durante oito meses. As caixas, modelo Langstroth, foram constru?das, instaladas e povoadas em um api?rio de col?nias de abelhas Africanizadas, com a mesma popula??o e parentesco da rainha. Acompanhou-se a temperatura interna, avaliou-se a condutividade t?rmica e a perda evaporativa das caixas de madeira e de ACV, n?o povoadas. Quando em col?nias, verificou-se seus padr?es de desempenho referentes ao controle t?rmico, da atividade de v?o, da ?rea de produ??o de favos e armazenamento de alimento, do peso da melgueira, do mel coletado e da sua qualidade qu?mica. As caixas e col?nias de ACV foram comparadas ?s de controle, de madeira, em um delineamento inteiramente casualizado, com dois n?veis de tratamento (tipo de material, in?cio e fim do estudo) e cinco repeti??es por tratamento, atrav?s da an?lise de vari?ncia. O peso da colm?ia padr?o ACV foi aproximadamente o dobro da de madeira e seu custo de US$15,19) foi 28,50% mais baixo que o da colm?ia de madeira. A temperatura m?dia interna das caixas e colm?ias de madeira e vermiculita foram semelhantes. Na caixa de ACV houve maior absor??o e perda mais r?pida de ?gua do que na de madeira. Apesar do controle t?rmico das col?nias de ACV, verificou-se que, eventualmente o intervalo da temperatura interna ultrapassou a faixa ?tima, o que pode ter ocasionado a redu??o da atividade de v?o, cuja diferen?a com a colm?ia de madeira foi significativa. A ?rea de forma??o de favos, de armazenamento de alimento e o peso do mel coletado n?o apresentaram diferen?as significativas, mas sofreram grande varia??o. A qualidade do mel amostrados nas colm?ias de ACV e madeira apresentaram-se dentro do padr?o rotineiro de an?lise qu?mica. Considerando-se que a caixa de ACV representa um modelo de constru??o artesanal, de baixo custo e caracter?sticas semelhantes ? caixa de madeira, sua utiliza??o torna-se mais uma alternativa vi?vel para o meio ap?cola, exceto para a atividade migrat?ria.

These interactions offer quantity and quality of environmental services to their river basins. This study characterized the Basin of the Guandu System (BHSG) and its flat land in relation to the offer of ecosystem services. Subsequently, it prospected on the factors that determine the supply and management of services as environmental assets in microbasins, strongly anthropized by mineral activity. Geoprocessing information was used to spatialize areas with similar ecosystem services and a local monitoring system to evaluate and size environmental services. The BHSG is home to Sepetiba marine fluvial plain in 50.21% of its area, whose altitude is less than 40 m, forms of flat or smooth undulating relief. In it interact the environmental effects produced by the rocky massifs of the high parts and the oscillations of the seas in the low parts. The combination of the contemporary geomorphological processes of the basin's hydrogel zones with their environmental attributes allowed the identification of homogeneous vocations of environmental services in the areas of abstraction and water regulation. As well, to identify the water effects where there is synergy between the Guandu rectified channel, built at 64 years and reserve areas around the original river bad, which were sectioned. In these places, there was an increase in upstream and downstream water flow reserve, which can be exploited for management purposes through the payment of environmental services. In the anthropogenic basin located in a region where the reservoir effects of the plain are inexpressive, the design of the water collection and management strategies in the riverbed with infiltration induction zones, through infiltration tanks, functioned as sediment retainers by preventing the emission of 29,000 t in 4 years. In addition to guaranteeing the supply of the average demand of 90 m3d-1 of raw water in a sparsely populated region with rainfall irregularity, historically exploited by subsistence agriculture, located in the peri-urban region of the RMRJ and with a predominantly negative annual climatic water balance, evidencing its potential to produce water under unfavorable conditions. / Nas plan?cies fl?vio marinha, presente ao longo da costa brasileira, existem intera??o intr?nseca entre os agentes coordenados pelas a??es do mar e a din?mica fluvial. Estas interagem e oferece quantidade e qualidade de servi?os ambientais ?s suas bacias hidrogr?ficas. Este estudo caracterizou a Bacia Hidrogr?fica do Sistema Guandu (BHSG) e sua plan?cie em rela??o a oferta de servi?os ecossist?micos. Posteriormente, prospectou sobre os fatores que determinam a oferta e manejo de servi?os como ativos ambientais em microbacias, fortemente antropizada por atividade mineral. Foram utilizadas informa??es de geoprocessamento para espacializar ?reas com servi?os ecossist?micos similares e sistema de monitoramento local para avaliar e dimensionar os servi?os ambientais. A BHSG abriga a plan?cie fl?vio marinha de Sepetiba em 50,21% de sua ?rea, cuja altitude ? inferior a 40 m, apresenta-se formas de relevo plano ou suave ondulado. Nela interagem os efeitos ambientais produzidos pelos maci?os rochosos das partes altas e as oscila??es dos mares nas partes baixas. A combina??o dos processos geomorfol?gicos contempor?neos das zonas hidrogen?ticas da bacia com seus atributos ambientais permitiu identificar voca??es homog?neas de presta??o de servi?os ambientais nas ?reas de capta??o e regula??o h?drica. Assim como, identificar os efeitos h?dricos onde h? sinergia entre o canal retificado do Guandu, constru?do a 64 anos e ?reas de reserva??o no entorno dos talvegues originais, que foram seccionados. Nestes locais, observou-se aumento da reserva??o dos fluxos h?dricos ? montante e diminui??o a jusante, que podem ser explorados para fins de manejo via pagamento de servi?os ambientais. Na bacia antropizada situado em regi?o onde os efeitos de reserva??o da plan?cie ? inexpressivo, o desenho das estrat?gias de coleta e administra??o h?drica nos talvegues com zonas de indu??o de infiltra??o, por meio de tanques de infiltra??es, funcionaram como retentores de sedimentos ao impedir a emiss?o de 29.000 t em 4 anos. Al?m de garantir o abastecimento da demanda m?dia de 90 m3d-1 de ?gua bruta em regi?o de escassa e com irregularidade de chuvas, explorada historicamente por agricultura de subsist?ncia, situada em regi?o periurbana da RMRJ e com balan?o h?drico climatol?gico anual predominantemente negativo no tempo, evidenciando o seu potencial de produ??o de ?gua em condi??es desfavor?veis

It was evaluated the effect of leaf spraying with liquid biofertilizer, obtained by fermented compost extract, and of dressing organic fertilization, in order to increase income for farmers of the region. The treatment were: okra (cv. Santa Cruz 47) sprayed or not with liquid biofertilizer, subjected to two doses of organic fertilization with castor cake (equivalent to 100 and 200 Kg of N-total ha-l), which were applied monthly or bimonthly, and started at 30 days after sowing. Okra was sown at double rows, with a spacing of 0.80 m inside the double row and 1.60 m between the double rows. Fruits were harvested with the size of 10 to 14 cm, according to the preference of national market. There were evaluated weight and number of produced fruits, as well as the yield estimated by the results of dry weight of fruits. Cv. Santa Cruz 47 is adapted to organic management, with mean yield of 16 Mg.ha-1. There were not detected significant differences among the evaluated treatments. This result indicates that the utilization of biofertilizer and the dressing fertilization applied monthly, in relation to bimonthly application, did not promote benefits to okra, according to the evaluated parameters. Considering edaphoclimatic conditions, the organic cultivation of okra in the autumn-winter period is viable, showing possibility to increase the income for farmers of the region. / Com objetivo de obter resultados que proporcionem alternativas vi?veis de incremento na renda dos agricultores, o presente trabalho estudou um sistema de produ??o org?nica do quiabeiro, cultivado nas esta??es de outono-inverno nas condi??es da Baixada Fluminense, avaliando-se o efeito da pulveriza??o foliar com biofertilizante l?quido, obtido a base de extrato de composto fermentado, e da aduba??o org?nica de cobertura, de forma a possibilitar uma oportunidade de renda aos agricultores da regi?o. Os tratamentos consistiram de: quiabeiro (cv.

Foram considerados, nas avalia??es, par?metros de produtividade, como o peso e o n?mero de frutos produzidos, sendo a produtividade estimada a partir dos resultados de peso seco dos frutos.. A Cultivar Santa Cruz 47 mostrou-se adaptada ao manejo org?nico, com produtividade m?dia pr?xima de 16 Mg.ha-1. N?o foram detectadas diferen?as devido aos tratamentos avaliados. Desse modo, a utiliza??o do biofertilizante n?o surtiu qualquer efeito ben?fico ? cultura, tendo em vista as vari?veis quantificadas, assim como a aduba??o mensal em cobertura da torta de mamona, n?o acarretou benef?cio superior ao obtido com a aplica??o bimensal. Considerando as condi??es edafoclim?ticas, o cultivo org?nico do quiabeiro no per?odo de outono inverno mostrou-se vi?vel, o que evidencia possibilidades de gera??o de renda para os agricultores da regi?o.

The use of the computer as a learning tool promoter is a constant challenge for educators. The creation, classification and maintenance of digital materials with educational content are laborious but essential tasks for the good use of technologies of information and communication in education, in various levels of education. In this context, the work that follows is intended to propose the creation of a reference model for implementation of a Learning Object Repository (LOR) as well as outlining a production process of these objects and choosing a team based on roles and responsibilities modeled in the process. As methodological approach was made a literature review on the subject. Conceptual maps were used to support the planning of the repository model. For choosing the set of metadata used in the model was made a Systematic Review of Literature (SRL) and after these steps the initial software interface has been validated through a survey instrument using the Likert scale for evaluation of non-functional software requirements applied to a group of educators and students of the academic community of IFES Campus Pi?ma. It is expected that the model will serve as a subsidy for the implementation of a repository for use by technical courses of Aquaculture and Fisheries of aforementioned campus, allowing the search and use of digital educational materials for teachers and students, in a simply and efficiently way / O uso de tecnologia na educa??o tem passado por uma s?rie de mudan?as. O uso do computador como ferramenta promotora da aprendizagem ? um desafio constante para os educadores. A cria??o, classifica??o e manuten??o de materiais digitais com conte?do educacional ? uma tarefa trabalhosa mas fundamental para o bom uso das TIC na educa??o, nos mais variados n?veis de ensino. Nesse contexto, o trabalho que se segue tem por objetivo propor a cria??o de um modelo de refer?ncia para implanta??o de um Reposit?rio de Objetos de Aprendizagem (ROA) bem como delinear um processo de produ??o destes objetos e de escolha de uma equipe, baseada em pap?is e responsabilidades modeladas no processo. Como percurso metodol?gico foi feita uma revis?o bibliogr?fica sobre o assunto. Foram utilizados mapas conceituais para apoiar a planejamento do modelo de reposit?rio. Para a escolha do conjunto de metadados utilizados no modelo foi feito uma Revis?o Sistem?tica de Literatura (RSL) e ap?s essas etapas a interface inicial do software foi validada atrav?s de um instrumento de pesquisa utilizando a escala Likert, para avalia??o de requisitos n?o funcionais de software, aplicada a um grupo formado por educadores e alunos da comunidade acad?mica do IFES Campus Pi?ma. Espera-se que o modelo proposto sirva de subs?dio para implementa??o de um reposit?rio para uso pelos cursos t?cnicos de Aquicultura e Pesca do campus supracitado, permitindo a busca e utiliza??o de materiais digitais educacionais, por professores e alunos, de forma simples e eficiente

Was adopted a completely randomized design with repeated measures in time (grazing cycles) and three replications (paddocks). The sward heights, in pre and post grazing were influenced by the clones and grazing cycles, being the highest values observed for clone CNPGL 03-01-00. The production of dry mass of green forage was influenced by clone and grazing cycle, with higher mean value observed for CNPGL 03-01- 00, which was 17% higher than that observed for CNPGL 92-198-7, and there was decreased of dry mass of green forage with the advance of grazing cycles. The production of dry matter of leaves was influenced only by grazing cycle, with gradual reduction from the first to the third cycle. However, in fourth cycle was increase in biomass of leaves, which did not differ from that observed in the second cycle. There was interaction clone x cycle for the production of dry matter of stem, being observed differences in the first and third cycles for the clones. There was no effect of the factors studied for the production of senescent material. The leaf: stem ratio was influenced by grazing cycles, with interaction of the factors. The clone CNPGL 91-198-7 kept the leaf:stem ratio stable over the cycles, while clone CNPGL 1-3-00 presented a decrease in leaf:stem ratio from first until to third cycle. The number of aerial tillers was influenced by grazing cycles, increasing from the first until to third cycle, while the fourth cycle was observed decreased in the number of these tillers. The basal tillers were only effect of clones, where CNPGL 91-198-7 showed a higher number of these tillers. Crude protein (CP) and lignin (LIG) content were not affected by clones or by grazing cycles. Neutral detergent fiber (NDF) and the in vitro dry matter digestibility (IVDMD) were affected only by grazing cycles. The highest values of NDF were observed at the firsts three grazing cycles and, in the fourth grazing cycle the NDF was reduced. The IVDMD decreased until the third cycle; however, in the fourth cycle the values obtained were similar to those of the first cycle. According to results obtained the clone CNPGL 92-198-7 showed higher production of dry matter of the leaves, lower production of dry matter of stem and higher density of basal tillers, which may indicate its greatest potential for use under grazing, when compared to CNPGL 01-03-00. / Objetivou-se estudar as alturas no pr? e p?s-pastejo do dossel forrageiro, a produ??o de biomassa seca de forragem verde, a composi??o morfol?gica, a rela??o folha:colmo, a densidade de perfilhos e o valor nutritivo de dois clones de capim-elefante manejados sob lota??o rotacionada. Foi utilizado delineamento inteiramente casualizado com medidas repetidas no tempo (quatro ciclos de pastejo) e tr?s repeti??es (piquetes). As alturas do dossel pr? e p?s pastejo foram influenciadas pelos clones e pelos ciclos de pastejo. Os valores mais elevados foram observados para o clone CNPGL 00-1-3. Para massa seca de forragem verde houve apenas efeito do clone e do ciclo de pastejo. O valor m?dio da massa seca de forragem verde do CNPGL 00-1-3 foi 17% maior do que a do CNPGL 92-198-7. Com o avan?ar dos ciclos de pastejo houve redu??o da massa seca de forragem verde. A produ??o de biomassa seca de folha foi influenciada apenas pelo ciclo de pastejo, com redu??o gradual do primeiro at? o terceiro ciclo. No quarto ciclo houve aumento na massa seca de folha, que n?o diferenciou daquela obtida no segundo ciclo. Houve intera??o clone x ciclo para a massa de colmo, sendo observadas diferen?as entre clones apenas no primeiro e terceiro ciclos. N?o foi observado efeito dos fatores estudados ou intera??o para a massa seca de material morto. A rela??o folha:colmo foi influenciada pelos ciclos de pastejo, havendo intera??o dos fatores estudados. O CNPGL 92-198-7 manteve a rela??o folha:colmo est?vel ao longo dos ciclos, enquanto que o CNPGL 00-1-3 apresentou decr?scimo na rela??o folha:colmo do primeiro at? o terceiro ciclo, com maior valor obtido no quarto ciclo. Quanto ao n?mero de perfilhos a?reos foi observado efeito dos ciclos de pastejo, com aumento do primeiro ao terceiro ciclo, enquanto que no quarto ciclo houve redu??o do n?mero desses perfilhos. Para os perfilhos basais houve efeito dos clones, onde o CNPGL 92-198-7 apresentou maior n?mero de perfilhos que o CNPGL 00-1-3. Os teores de prote?na bruta (PB) n?o foram influenciados pelos clones ou pelos ciclos de pastejo. Os teores de fibra em detergente neutro (FDN) e o coeficiente da digestibilidade in vitro da mat?ria seca (DIVMS) foram influenciados apenas pelos ciclos de pastejo. Os maiores valores de FDN foram observados nos tr?s primeiros ciclos de pastejo, j? no quarto ciclo de pastejo o teor de FDN reduziu. Quanto ? DIVMS houve queda at? o terceiro ciclo, enquanto que no quarto ciclo os valores obtidos foram semelhantes aos do primeiro ciclo. Para lignina n?o foi observada diferen?a dos fatores estudados. De acordo com os resultados obtidos, o clone CNPGL 92-198-7 apresentou maior produ??o de biomassa seca de folhas, menor produ??o de biomassa seca de colmo e maior densidade populacional de perfilhos basais, o que pode indicar seu maior potencial para uso sob pastejo, quando comparado ao CNPGL 00-1-3.

However, when I got my masters degree, I was invited to re-read my writings. As I re-read it I realized that I did not write about the racial issue. This absence became a highly relevant fact that made me realize and question myself about the powerful of schooling that taught me to be a man, or rather to be male, white, heterosexual and christian, fundamentally. So today, I visualize that a "pedagogy" circulates within different educational spaces (at school, in the family, in religious spaces, in leisure spaces, in the media, in the street, at work, etc.) that ends up (re)producing inequalities of race, gender and sexuality. In this perspective, social markers of race, gender and sexuality will be presented in a vision, intersectional, polymorphic and polyphonic. According to Narrative Studies; I conjugate the verb to write/search attached to the verb to exist. And so, I'm narrating what happens to me, I write what touches me as a minor people, bastard, always unfinished. / Eu cresci escrevendo di?rios ?ntimos. No entanto, quando cheguei ao mestrado, fui convidado a re-ler os meus escritos. ? medida que ia re-lendo percebi que n?o escrevia sobre a quest?o racial. Essa aus?ncia, tornou-se um dado altamente relevante que fez com que eu percebesse e me questionasse sobre os poderosos ?instrumentos de escolariza??o? que me ensinaram a ser homem, ou melhor, a ser macho, branco, heterossexual e crist?o, fundamentalmente. Ent?o, hoje, visualizo que no interior de diferentes espa?os educativos (na escola, na fam?lia, nos espa?os religiosos, nos espa?os de lazer, na m?dia, na rua, no trabalho, etc) circula uma ?pedagogia? que acaba por (re)produzir desigualdades de ra?a, g?nero e sexualidade. Nesta perspectiva, os marcadores sociais de ra?a, g?nero e sexualidade ser?o apresentados em uma vis?o, interseccional, polim?rfica e polif?nica. Baseando-me na ?pedagogia narrativa?; conjugo o verbo escrever/pesquisar atrelado ao verbo existir. E, assim, vou narrando aquilo que me acontece, escrevo o que me toca enquanto um povo menor, bastardo, sempre inacabado.
