Para isso foram realizadas medi??es das vaz?es dos gotejadores, em talh?es de caf? com idade de 5 anos. Os gotejadores foram selecionados utilizando-se a metodologia proposta por KELLER & KARMELI. Por meio dos resultados dos c?lculos obtidos a partir dos dados coletados em campo, estimou-se o volume de ?gua aplicado, o consumo de energia real de cada propriedade rural e kg de gr?os produzido por l?mina de ?gua aplicada pelo produtor. Em seguida, com as informa??es da evapotranspira??o real, da evapotranspira??o da cultura, efici?ncia do sistema de irriga??o e Kc da cultura do caf?, determinou-se o volume de ?gua e o consumo de energia el?trica simulados para a condi??o de manejo adequado da irriga??o nas propriedades em estudo, no per?odo de janeiro a julho de 2009. Os resultados obtidos permitiram concluir que, em fun??o da inexist?ncia de um manejo adequado da irriga??o, 75% e 25% das propriedades em estudo apresentaram, respectivamente, aplica??o em excesso e em d?ficit de ?gua. Essa falta de manejo dos sistemas de irriga??o teve implica??o direta no consumo de ?gua, de energia el?trica e de kg de gr?os produzido por mm de ?gua aplicada na cultura do caf? nas propriedades pesquisadas durante o per?odo do estudo. / Disserta??o (Mestrado) ?

For that were realized measurements of flow in the leaking system using plots of coffee with 5 years old and the tools were selected using the methodology wich was proposed by KELLER & KARMELI. Through the results obtained from data colecting in field it was possible to the estimate the volume of applied water, energy consumption in each rural property?and kg of grain produced?by water shade. Then, with the information about real evapotranspiration, evapotranspiration of culture, irrigation system efficency and Kc of coffee culture, it was determined water volume and eletric energy consumption simulated?to the condition of adequated irrigation handling in the properties of study from January to July of 2009. In conclusion, the results? showed that due to inexistence of adequated irrigation handling, 75% and 25% of the studied?properties presented, respectively,? use of water in excess and in lack. This lack of handling in the irrigation system had direct inference in water consumption, electric energy and kg of produced grains per mm of applied water in coffee culture in the studied properties during the period of the work.

O objetivo deste trabalho foi verificar os fatores ambientais (localiza??o geogr?fica), proced?ncia, prog?nie, ?cido giber?lico e tempo de armazenamento das sementes na emerg?ncia de pl?ntulas dessa esp?cie. Foram coletadas sementes de prog?nies (matrizes) oriundas dos munic?pios mineiros de S?o Gon?alo do Rio Preto, Curvelo e Serro ? distrito de S?o Gon?alo do Rio das Pedras. As sementes foram coletadas em janeiro de 2005 e 2007 para o experimento 1 e em janeiro de 2007 e 2008 para o experimento 2, sendo semeadas em dois munic?pios: Diamantina (ambiente de baixa temperatura) e Curvelo (ambiente de alta temperatura). Os dados foram analisados atrav?s de testes Qui-quadrado para independ?ncia. Para os experimentos 1 e 2, conduzidos em Curvelo, todos os fatores foram altamente significativos (P<0,1%), exceto o efeito de proced?ncia (P = 6,89%) e do ?cido giber?lico (P = 6,08%), ambos do experimento 1. No experimento 1, conduzido em Diamantina, nenhum fator foi significativo a 10%, exceto o tempo de armazenamento (P = 5,64%) e o efeito ambiental (P<0,01%). J? no experimento 2, conduzido em Diamantina, todos os fatores foram significativos a 5%. A n?o signific?ncia para a maioria dos fatores em Diamantina no experimento 1 foi em decorr?ncia da baix?ssima taxa de germina??o nesse ambiente (apenas 11 sementes germinaram, de um total de 2010). A diferen?a de germina??o foi tamb?m significativa entre os dois ambientes - Curvelo e Diamantina, para os dois experimentos. Entretanto, no experimento 2, a germina??o foi menor em Curvelo, contrariando as expectativas. Acredita-se que a ocorr?ncia desse fato seja porque no ano de 2008 a sementeira em Diamantina foi montada no ch?o e n?o suspensa, como em Curvelo. A varia??o t?rmica seria maior no leito de areia suspenso por estar com a parte inferior exposta ? temperatura ambiente. Conclui-se que: a) a emerg?ncia em pl?ntulas de pequizeiro ? influenciada tanto por fatores gen?ticos como ambientais; b) a frequ?ncia de emerg?ncia em pl?ntulas de pequizeiro ? altamente influenciada pela planta matriz da qual foram colhidas; c) O efeito de popula??es (proced?ncias) na emerg?ncia em pl?ntulas de pequizeiro pode ser decorrente do pequeno tamanho dessas popula??es, confundindo-se com o efeito de matrizes; d) O tratamento de sementes de pequizeiro com ?cido giber?lico pode n?o ser garantia de maior emerg?ncia; e) O tempo de armazenamento de sementes de pequizeiro influencia consideravelmente a taxa de emerg?ncia. / Disserta??o (Mestrado) ?

Observations show that temperature fluctuations, a common phenomenon observed among different altitudes, seems to have a strong influence on pequi seeds emergency. Genetic factors appears also to play an important role on this issue. These were the main focus on this work. Seeds from many progenies from three pequi populations (S?o Gon?alo do Rio Preto; Curvelo; and Serro, all of them in Minas Gerais State), strongly distanced from each other, were collected. The 3997 seeds collected in January of 2005 and 2007 years (Trial 1) and the 7035 ones collected in January of 2007 and 2008 years were sown proportionally in Diamantina, MG (a high altitude environment - roughly 1400m) and Curvelo, MG (a low altitude environment ? roughly 650m). The data were collected and organized in contingence tables. The hypothesis for population, progeny (tree), gibberellic acid (GA3), seed age (date of collection) and altitude (temperature) effects were tested by qui-square test for independence. For the trials carried out in Curvelo (high average temperature) in 2007 year, all tested effects were significant (P<0,1%), except populations (P=6,9%) and GA3 (P=6,1%), the last one reducing instead of, as expected, increasing the emergency rate. In the trials carried out in Diamantina (low average temperature) in 2007 year, the probabilities for qui-square tests were all over 10% except seed age (P=5,6%) and progenies (P=9,7%). In 2008 year all effects were significant (P<5%) for both locations. The temperature effects were also significant (P<5%) for the two years, however, against the expectations, in 2008 year, Curvelo (high average temperature) showed a lower emergency rate than Diamantina. The hypothesis to explain it was that the seed plot position was put directly on ground in Diamantina in this year, contrasting with the lifted ones in both locations in 2007 year and in Curvelo in 2008 year. This hypothesis was tested by comparing seed plots lifted with those sow directly on ground in both locations. The results showed that the emergency rate was significantly lower in the seed plots lifted in both Diamantina and Curvelo locations compared to those put directly on ground. May be the night and day temperature fluctuations affect more intensely the lifted seed plot. The main conclusions were: a) pequi seeds emergency are influenced by both genetic and environmental factors; b) it is highly influenced by their original progeny tree; c) progeny tree can also be the main factor responsible for population effects when the population sample is small; d) gibberellic acid is not a guarantee for better emergency in pequi seeds; e) the storage time has a considerable influence on their emergency rate; f) strong day and night temperature fluctuations can reduce the emergency rate in pequi seeds.

No entanto, pouca import?ncia foi dada ? sua cultura, a qual apenas nos ?ltimos anos vem sendo estudada, o que deixou um grande leque de informa??es em aberto, como as suas limita??es nutricionais e distribui??o dos nutrientes, por exemplo. Os objetivos destes trabalhos foram (a) avaliar as limita??es nutricionais no crescimento de mudas de pinh?o manso em Neossolo Quartzar?nico ?rtico t?pico e (b) avaliar as exig?ncias nutricionais de mudas de pinh?o manso sob omiss?o, ac?mulo e distribui??o de nutrientes nas diferentes partes da planta. Os experimentos foram conduzidos em condi??es de casa de vegeta??o do Departamento de Agronomia da Universidade Federal dos Vales do Jequitinhonha e Mucuri (Diamantina-MG). O primeiro experimento foi realizado com mudas de pinh?o manso cultivadas em vasos contendo Neossolo Quartzar?nico, submetido aos seguintes tratamentos: completo (adubado com N, P, K, Ca, Mg, S, B e Zn), testemunha (solo natural) e a omiss?o de um nutriente por vez (-N, -P, -K,-Ca, -Mg, -S, -B e -Zn), disposto em delineamento inteiramente casualizado, com cinco repeti??es. Ap?s 100 dias, foram avaliadas as seguintes caracter?sticas: altura das mudas, di?metro do caule, peso de massa seca da parte a?rea e das ra?zes e teor de macro e micronutrientes na massa seca da parte a?rea. O segundo foi conduzido em delineamento experimental inteiramente casualizado com quatro repeti??es e nove tratamentos. Os tratamentos consistiram de solu??o nutritiva completa e com omiss?o de N, P, K, Ca, Mg, S, B e Zn, pelo uso da t?cnica do elemento faltante. Ap?s 100 dias, foram avaliadas as seguintes caracter?sticas: peso de massa seca do limbo foliar, do pec?olo, da folha completa (limbo foliar + pec?olo), do caule, da parte a?rea e de ra?zes e teor de nutrientes na massa seca de cada parte das mudas de pinh?o manso. Pelos resultados obtidos, pode-se concluir: (1) todos os nutrientes foram limitantes para o crescimento das mudas de pinh?o manso no Neossolo Quartzar?nico, exceto o N, sendo que a sequ?ncia de limita??o nutricional foi P, Mg, Zn, Ca, K, S, B e N; (2) o pinh?o manso foi altamente exigente em todos os nutrientes na fase de crescimento e (3) o ac?mulo total de macronutrientes e micronutrientes se deu na seguinte forma na ordem decrescente: N>K>Ca>P>Mg>S e Fe>Cu>Mn>B>Zn, respectivamente, com maior ac?mulo na folha completa, ocorrendo uma invers?o de maior ac?mulo entre N e K para macronutrientes e Fe e Cu para micronutrientes no caule das mudas de pinh?o manso. / Disserta??o (Mestrado) ?

However, little attention was given to its culture, which only in recent years has been studied, leaving a wide range of information in open, as their nutritional limitations and distribution of nutrients. The objectives of this work were (a) assess the nutritional limitations on physic nut seedling growth in tipic Ortic Quartzarenic Neossol and (b) assess the nutritional requirements of physic nut seedlings under omission, accumulation and distribution of nutrients in different parts of the plant. The experiments were carried out in greenhouse at the Agronomy Departament of UFVJM (Diamantina-MG). The first experiment used the physic nut seedlings, which was cultivated in pots with Quartzarenic Neossol under the following treatments: a complete treatment (fertilized with N, P, K, Ca, Mg, S, B and Zn), a control one (natural soil) and the absence of those nutrients per pot treatment, prepared in a completely randomized design with five repetitions. Plant height, stem diameter, dry weight mass of shoot and roots and content of macro and micronutrients in dry matter shoots were evaluated after 100 days. The second was the experimental design completely randomized, with four replications and nine treatments. The treatments consisted of a complete nutritive solution and with omission of N, P, K, Ca, Mg, S, B and Zn, using the missing element technique. Dry matter of the leaf blade, of the petiole, of the complete leaf (leaf blade + petiole), of the stem, of the shoot and of the roots and the nutrient content in dry matter of each parts of the physic nut seedlings were evaluated after 100 days. By the results, can be concluded: (1) all nutrients were limiting for the physic nut seedlings growth in Quartzarenic Neossol, except for the N, and the nutritional limitation was P, Mg, Zn, Ca, K, S, B and N; (2) the physic nut was highly demanding for all nutrients in the growth phase and (3) the total accumulation of macronutrients and micronutrients in descending order: N>K>Ca>P>Mg>S and Fe>Cu>Mn>B>Zn, respectively, with bigger accumulation in the complete leaf, occurring an inversion of bigger accumulation between N and K for macronutrientes and Fe and Cu for micronutrients in the stem of the physic nut seedlings.

O manejo adotado geralmente se resume ao armazenamento desses dejetos e posterior aplica??o no solo sem um tratamento pr?vio, constituindo um fator de polui??o ambiental. Dessa forma torna-se necess?rio a utiliza??o de dispositivos que promovam a redu??o do potencial poluidor dos dejetos e o reaproveitamento integral desses res?duos como forma de resgate de parte da energia empregada no processo produtivo. Diante disso os objetivos desse trabalho foram avaliar a efici?ncia do sistema de lagoas de estabiliza??o em s?rie na redu??o do potencial poluidor dos dejetos l?quidos de su?nos em uma granja comercial em ciclo completo com 500 animais, com vistas ao seu reaproveitamento como biofertilizante e estimar a quantidade de energia para produ??o de su?nos em ciclo completo e o balan?o energ?tico do sistema com reaproveitamento dos res?duos gerados como biofertilizante em ?rea de pastagem. Foram coletadas amostras em diferentes pontos do sistema de tratamento e efetuadas as an?lises dos seguintes par?metros: pH, Demanda bioqu?mica de oxig?nio (DBO), Demanda qu?mica de oxig?nio (DQO), S?lidos totais (ST), S?lidos totais fixos (STF), S?lidos totais vol?teis (STV), S?lidos suspensos totais (SST), S?lidos suspensos fixos (SSF), S?lidos suspensos vol?teis (SSV), Nitrog?nio total (N-Total), F?sforo (P), Pot?ssio (K), C?lcio (Ca) e Magn?sio (Mg). Quantificou-se o coeficiente energ?tico de cada componente envolvido no processo produtivo de su?nos terminados, tratamento dos res?duos e produ??o de pastagem de Brachiaria decumbens, nas formas de ra??o, trabalho humano, energia el?trica, m?quinas e equipamentos, combust?veis e lubrificantes, instala??es, produ??o de su?nos vivos e produ??o de Brachiaria decumbens. A remo??o da carga org?nica obtida pelo sistema de lagoas de estabiliza??o em s?rie foi de 84,38% da DBO e 85,27% para a DQO. A s?rie de s?lidos apresentou comportamento semelhante e os nutrientes N-Total, P, K, Ca e Mg foram removidos em 28,30; 63,46; 12,24; 42,84 e 74,95% respectivamente. O sistema foi eficiente na remo??o da carga org?nica e o efluente tratado demonstrou caracter?sticas favor?veis ao seu reaproveitamento como biofertilizante. No sistema de produ??o de su?nos avaliado, a quantidade m?dia de energia para produzir 1 kg de su?no vivo foi de 53,35 MJ.

The management adopted generally comes to storage and subsequent application of manure in the soil without prior treatment, constituting a factor of environmental pollution. Thus it is necessary the use of devices that promote the reduction of the pollution potential of waste reuse and full of waste as a way of redemption of part of the energy used in the production process. Considering that the objectives of this study were to evaluate the efficiency of stabilization ponds in series to reduce the pollution potential of liquid pig manure on a commercial farm in full cycle with 500 animals, with a view to its reuse as biofertilizer and estimate the quantity of energy for production of pigs in complete cycle and energy balance of the system to reuse the waste generated as biofertilizer in area of pasture. Samples were collected at different points in the system of treatment and performed the analysis of the following parameters: pH, Biochemical Oxygen Demand (BOD), Chemical oxygen demand (COD), Total solids (TS), Total fixed solid (STF), Solid total volatile (STV), Total suspended solids (TSS), Suspended solids fixed (SSF), Volatile suspended solids (VSS), Total nitrogen (Total-N), Phosphorus (P), Potassium (K), calcium (Ca) and Magnesium (Mg). We quantified the energy coefficient of each component involved in the production process of finished pigs, waste treatment and production of pasture of Brachiaria decumbens in the form of food, human labor, energy, machinery and equipment, fuels and lubricants, plant, production of live pigs and production of Brachiaria decumbens. The removal of organic load produced by the system of stabilization ponds in series was 84.38% and 85.27% of BOD to COD respectively. The series showed similar behavior of solids and nutrients-Total N, P, K, Ca and Mg were removed at 28.30, 63.46, 12.24, 42.84 and 74.95% respectively. The system was efficient in removing the organic load and the treated effluent has characteristics favorable to its reuse as biofertilizer. The production system of pigs evaluated, the average amount of energy to produce 1 kg of live pigs was 53.35 MJ. Of all energy used in the 76.03% (MJ 1,067,106.07) refer to inputs and 23.97% (331,400 MJ) the exits, resulting in a coefficient of efficiency of 0.31. The energy transformed into pigs for slaughter was 55.58% (184,200 MJ) of output, while the pasture of Brachiaria decumbens took a value of 44.42% (147,200 MJ) indicating that the use of pig waste in the chain promoted renewal of energy, reducing environmental impacts and minimizing the import of energy.

However, little attention has been given the diagnosis of the nutritional status of coffee that provides greater productivity and, together with productivity, improved quality of the drink. The DRIS standards have not yet been set for the coffee yield in Valley do Jequitinhonha, thus the absence of such rules prevent the DRIS is applied in that region's coffee culture. The diagnosis leaf, using the Integrated System Diagnosis and Recommendation (DRIS) and tracks critical of reference, stands out among the potential tools that allow efficiently diagnose the nutritional status of the plants. The objectives of this study were (a) establish the rules DRIS, propose suitable for tracks levels of nutrients and leaf diagnose nutritional of coffee (Coffea arabica L.) of the High Jequitinhonha Valley; (b) carry out lifting the quality of the coffee drink and (c) set the standards DRIS, propose appropriate tracks of nutrients and assess the nutritional status of coffee for higher productivity and better quality of the drink. Those results, we can conclude: (1) higher percentage of crops in nutritional imbalances were observed for nutrients P, S, B, Cu, Zn Mn and in disability, and the Mg and the excessive Fe; (2) The DRIS to diagnose nutritional standards were established for coffee in the region of the High Jequitinhonha Valley, MG and tracks used to propose critical for N (2.25 - 2.79 dag kg-1), P (0.18 - 0, 22 dag kg-1), K (1.72 - 2.10 dag kg-1), Ca (1.26 - 1.51 dag kg-1), Mg (0.29 - 0.35 dag kg-1 ), S (0.13 - 0.32 dag kg-1), B (83.8 - 96.3 mg kg-1), Cu (5.7 - 9.3 mg kg-1), Fe (67 , 5 to 116.2 mg kg-1), Mn (219 - 422 mg kg 1) and Zn (17.4 - 30.0 mg kg 1); (3) by lifting the quality of the coffee drink there was that most of the crops in the region had assessed quality of the drink classified as "hard", but the region presents ability to produce higher quality coffee (drink "soft", "just soft" and "strictly soft"); (4) DRIS standards for the nutritional status along with the quality of the drink of coffee were down for coffee in the region of the High Jequitinhonha Valley, MG and from these standards, the tracks were proposed critical nutrients N (2.20 - 2.48 dag kg-1), P (0.20 - 0.24 dag kg-1), K (1.49 - 1.79 dag kg-1), Ca (1.30 - 1.61 dag kg-1), Mg (0.32 - 0.38 dag kg-1), S (0.10 - 0.13 dag kg-1), B (77.3 - 89.1 mg kg-1), Cu (3.1 - 3.8 mg kg-1), Fe (174.0 - 242.4 mg kg-1), Mn (197.5 - 341.8 mg kg-1) and Zn (19.8 - 31.0 mg kg-1) as tracks appropriate for the better nutritional status and quality of the coffee beverage for the region of Minas; (5) for the diagnosis of the nutritional quality of coffee to drink noted that maintaining the balance of the nutritional status of crop, provides high productivity and quality of the coffee beverage.

Este trabalho faz parte do projeto n? 2008-3.08/07 Fapemig, em parceria com a ARMICOPA (Associa??o Regional Mucuri de Coopera??o dos Pequenos Agricultores). As amostras de solo foram coletadas em quatro localidades nos munic?pios de Ladainha, Novo Oriente, Pot? e Cara?, sendo que em cada localidade foram amostradas ?reas de pastagem, ?rea de cultura e remanescente florestal. Foram realizadas determina??es de atributos f?sicos, qu?micos e ligados ? mat?ria org?nica do solo de todas as ?reas. A composi??o flor?stica foi realizada nos quatro remanescentes florestais do bioma Mata Atl?ntica com Floresta Estacional Semidecidual. Foram alocadas nove parcelas de 10 x 10m, totalizando 900m? em cada ambiente de mata ciliar. O material bot?nico foi coletado dentro de cada parcela, sempre procurando atingir a maior diversidade poss?vel de esp?cies por fragmento. Dentre os agroecossistemas analisados, a mata foi a que apresentou melhor qualidade dos atributos do solo, o que indica que o uso e manejo influenciam diretamente sobre esses atributos. Nas quatro ?reas de mata ciliares foram identificadas 149 esp?cies, distribu?das em 81 g?neros e 40 fam?lias.

This work takes part of the project n?00 Fapemig in partnership with ARMICOPA (Mucuri Regional Association for Cooperation to Small Farmers). The soil samples were collected in four areas of the municipal districts of Ladainha, Novo Oriente, Pot? and Cara?, considering that in each place there were collected samples of pasture, culture and remnant forest areas. Determination of physical, chemical and linked to the organic matter of the soil attributes was accomplished in all areas. The floristic composition was accomplished in four remnant forests of Atlantic forest with Seasonal Semidecidual Forest bioma. Were allocated nine 10 x 10m portions, totaling 900m? in each ciliary forest environment. The botanical material was collected in each portion always attempting to reach the largest species diversity possible per fragment. Among the analyzed agroechossistems, the forest was the one that presented better quality of the soil attributes, indicating that the use and handling can influence directly on those attributes. In the four ciliary forest areas 149 species were identified, distributed in 81 genders and 40 families. The results are aimed at subsidizing the recovery of those environments with agroforests systems developing, once the Mucuri Valley microrregion lacks of studies about the possibilities of maintainable use.

Apesar de ser uma das oler?colas mais cultivada no Brasil e apresentar grande potencial de uso na alimenta??o humana, animal e industrial, tem sido pouco estudada. O objetivo deste trabalho foi identificar clones superiores e avaliar a produ??o e a qualidade de ra?zes, ramas e silagem de ramas de clones de batata-doce em diferentes ?pocas de colheita e ambientes de cultivo. Foi realizado um experimento no Campus II e outro na Fazenda Forquilha, ambos localizados no munic?pio de Diamantina-MG, com tr?s ?pocas de colheita. Foram avaliados nas ra?zes tuberosas: a produtividade total, produtividade comercial, peso m?dio total, peso m?dio comercial, resist?ncia a insetos de solo, formato de ra?zes, prote?na bruta, fibra bruta, cinzas, amido, compostos fen?licos e herdabilidade. Na parte a?rea foi avaliado a produtividade de mat?ria verde, teor de mat?ria seca, produtividade de mat?ria seca, prote?na bruta e fibra bruta. Foi feito silagem das ramas aos 150 dias ap?s a colheita na Fazenda Forquilha, onde foi analisado prote?na bruta, FDA, FDN, NDT, pH, mat?ria seca, hemicelulose e nitrog?nio amoniacal em rela??o ao nitrog?nio total. Atrav?s dos resultados apresentados, percebe-se que Os clones BD-25, BD-38 e BD-45, na Fazenda Forquilha, apresentaram as maiores produtividade totais e comercial de ra?zes e devem ser colhidas mais tardiamente. A Fazenda Forquilha foi o local onde os clones de batata-doce apresentaram, em m?dia, as maiores produtividades totais e comercial de ra?zes e os maiores pesos m?dios de ra?zes total e comercial. As menores notas para formato de ra?zes foram obtidas nas colheitas mais precoces. Os teores de prote?na bruta, fibra bruta, cinzas e amido, na mat?ria seca de ra?zes, n?o foram influenciados pelos ambientes de cultivo. Para obten??o de maiores produtividades de mat?ria verde e mat?ria seca, as ramas devem ser colhidas at? 150 dias ap?s o plantio.

Despite being one of most vegetables grown in Brazil and show great potential for use in food, animal and industrial, have been little studied. The objective was to identify superior clones and assess the production and quality of roots, stems and branches of silage from sweet potato clones in different harvesting periods and environments of cultivation. An experiment was conducted on campus and another on Farm II forks, both located in the city of Diamantina-MG with three seasons of harvest. Roots were evaluated in the total yield, commercial yield, total weight, weight commercial, insect resistance of soil, shape of roots, crude protein, crude fiber, ash, starch, phenolic compounds and heritability. In shoots was evaluated the yield of green matter, dry matter yield of dry matter, crude protein and crude fiber. Silage was made of branches to 150 days after harvest at Farm forks, where it was considered crude protein, ADF, NDF, TDN, pH, dry matter, hemicellulose and ammonia nitrogen in relation to total nitrogen. The results presented, we find that the BD-25 clones, and BD-38 BD-45, at Farm forks, submitted the highest total and commercial yield of roots and should be harvested later. The Farm was the fork where the sweet potato clones showed, I mean, the highest total and commercial yields of roots and the highest average weight of roots and total trade. The lowest notes to format roots were in earlier harvests. The crude protein, crude fiber, ash and starch in dry matter of roots were not influenced by the environment of cultivation. To obtain higher yields of green matter and dry, the stems should be harvested up to 150 days after planting. Farm forks were obtained in the highest yield of green matter and dry matter of branches. The dry matter in branches increased with the crop cycle. The stems of sweet potato, have potential for use in animal feed, both as fresh and as silage.

O controle das plantas daninhas nestas ?reas ? realizado predominantemente pelo uso de herbicidas com longo per?odo residual, destacando-se o picloram. Este ? utilizado no controle de plantas daninhas de folhas largas perenes e tem sido intensamente pesquisado em fun??o da alta meia vida nos solos, sendo sua persist?ncia dependente do clima e atributos ed?ficos, como textura e pH. Objetivou-se com este trabalho avaliar o desenvolvimento e o potencial remediador de B. brizantha em solo contaminado com picloram em diferentes n?veis de pH. O delineamento experimental utilizado foi em blocos casualizados, com quatro repeti??es e com faixa de pH variando entre 4,5 e 5,6. Cultivou-se a forrageira at? a flora??o, quando se determinou a massa da mat?ria seca dos componentes da planta e posteriormente, cultivou-se plantas de pepino como indicadores da presen?a do herbicida. O picloram causou redu??o no ac?mulo da massa da mat?ria seca total das plantas de B. brizantha, em consequ?ncia do efeito negativo sobre a produ??o de ra?zes, independente do pH do solo. Nas folhas o herbicida promoveu redu??o na massa da mat?ria seca em solo com maior pH. Nos tratamentos com maior valor de pH, na profundidade de 35 cm, constatou-se maior ac?mulo de massa da mat?ria seca de ra?zes quando n?o se aplicou o herbicida, indicando que em solos menos ?cidos o herbicida tende a prejudicar o desenvolvimento de ra?zes da forrageira em maiores profundidades. A B. brizantha reduziu a concentra??o de picloram na camada superficial de solo, o que pode ser atribu?do a sua capacidade de degradar o herbicida e tamb?m ao fato desta absorver e exsudar o herbicida ao longo das camadas de solo. Observou-se tamb?m que em solos com maiores valores de pH o herbicida tem maior potencial de lixivia??o, principalmente quando n?o cultivado com B. brizantha. Solos com menores valores de pH tendem ? maior sor??o do herbicida, e consequentemente, a maior concentra??o do mesmo em camadas intermedi?rias. Pode-se concluir que altas concentra??es de picloram no solo s?o nocivas ao crescimento da B. brizantha, principalmente sob condi??es de solos menos ?cidos e esta forrageira pode ser usada para remedia??o de solos contaminados por picloram e na preven??o de sua lixivia??o, que ? maior em solos tratados com calc?rio. / Disserta??o (Mestrado) ?

The weed control in these areas is carried out predominantly using herbicides of long residual period, highlighting the picloram. This herbicide is used for weed control broadleaf evergreen and has been intensively investigated due to the high half-life in soil, and their persistence dependent on climate and soil attributes such as texture and pH. The aim of this work was to evaluate the development and potential remediation of B. brizantha in soil contaminated with picloram at different pH levels. The experimental design was a randomized block with four replications and pH among 4.5 and 5.6. The forage was grown up to flowering, when determined the dry weight of the plant components and subsequently were cultivated cucumber plants such as bioindicators of presence of the herbicide. The picloram caused reduction of total dry matter accumulation of B. brizantha, consequently to negative effect on root production, regardless soil pH. The herbicide caused a reduction of leaf dry matter on plants cultivated in higher soil pH. In treatments of high pH value at a depth of 35 cm, there was greater accumulation of dry matter of roots when the herbicide was not applied, indicating that in less acid soils the herbicide tends to hinder the development of grass root at greater depths. B. brizantha reduced picloram concentration in the soil shallow layer, which can be attributed to its ability of degrade the herbicide, and also by fact of absorption and exudation herbicide along the soil layers. In higher pH soils also observed that ??the herbicide has higher potential for leaching, mainly when not cultivated B. brizantha. Soils with lower pH values ??tend to greater sorption of the herbicide, and consequently, a higher concentration of the same in the intermediate layers. Concluded that high concentrations of picloram in the soil are harmful to the growth of B. brizantha, mainly under conditions of soils less acidic and this forage can be used for remediation of soils contaminated by picloram and preventing leaching, which is greater in soils treated with lime.

The experiments were conducted on the Mape Fruits Farm Ltda, located in Datas - MG, in the Laboratory of Biomass Technology of the Cerrado, in the UFVJM. We assessed eight strawberry cultivars: six short days (Festival, Campinas, Toyonoka, Dover, Oso Grande and Camarosa), and two neutral days (Diamante, Aromas), using statistical designs specific to each experiment. The fruits were harvested twice a week from May to October 2012. Cultivar Dover was the one that produced the largest number of seedlings per array and larger number of seedlings per hectare. The Aromas and Diamante showed greater yield early fruit. There were significant differences among cultivars for plant production and overall productivity of fruits, except for the cultivar Toyonoka presented the lowest values ??for these features. The cultivars Camarosa, Diamante, Oso Grande Festival and had the highest yields per plant and commercial greatest commercial yields of fruit. The highest total productivities were obtained in the months of June, July and September. The greatest commercial yields were obtained in June. The cultivars Camarosa, Festival and Toyonoka showed the best physical and chemical characteristics and antioxidants properties. Cultivar Toyonoka had the lowest amount of aerobic mesophilic and Oso Grande cultivated the least amount of mold and yeast. Fruit harvested in October showed higher levels of total reducing sugars, vitamin C, phenolics, anthocyanin, carotenoids, antioxidant activity and soluble solids. The mass loss of the fruits is increased in ambient storage conditions when compared to cold storage. The cold storage provides greater post-harvest conservation of strawberry fruits. In natural conditions the fruits can be stored for a maximum of three days. Already in cold storage of strawberry fruits can be extended for up to twelve days. Cultivar Toyonoka despite having the best physical and chemical characteristics, features coupled with the variety Campinas, higher incidence of disease, greater weight loss and lower fruit firmness compared with other cultivars, requiring adoption of other conservation practices fruits. The weight loss and the incidence of diseases negatively affect the appearance of the fruit of strawberry during storage in a cold chamber at ambient condition while the incidence of disease decreases the quality of the appearance of the fruit of strawberry.

Estes perfis foram descritos e amostrados para caracteriza??o proposta. Foram realizadas an?lises qu?micas e f?sicas de rotina. Os teores totais de Fe, Ti, Al, Mn e Si foram determinados pelo ataque sulf?rico e os ?xidos de Fe, Al e Mn foram avaliados nos extratos de ditionito-citrato-bicarnonato e oxalato. A mineralogia foi identificada pela difratometria de raios-X e os ?xidos de Fe foram identificados pela difratometria diferencial de raios-X. Por espectrometria de fluoresc?ncia de raios-X foram determinados Ti, Ga e Zr.Todos os solos apresentaram atributos morfol?gicos, f?sicos, qu?micos e mineral?gicos t?picos da classe dos Latossolos. P20 apresentou cores acinzentadas, significativos fragmentos de estrutura maci?a, caracter?stica de Gleissolos, nos horizontes A e BA. Todos os perfis s?o muito argilosos, distr?ficos, com baixos teores de P dispon?vel e pH em torno de 5. Os ?xidos de Fe, de modo geral, refletiram a cor dos solos e diminu?ram ao longo da vertente. A diminui??o de Fe cristalino e de baixa cristalinidade ao longo da vertente confirmou a perda de Fe. O Si seguiu o caminho inverso e o Al total permaneceu constante. A diminui??o da rela??o Fe2O3/TiO2 em P20 indicou problemas de drenagem neste solo. A mineralogia da fra??o argila em todos os perfis ? dominada por caulinita e gibbsita.

The objective of this work went characterize morphologically, micromorphologically, chemically, physically and mineralogically a Xanthic Haplustox (?LAC?) in toposequence formed by representative Oxisol of the soils of the tableland occupying most of the land agricultural the region of the Alto Vale do Jequitinhonha, MG, emphasizing aspects of its genesis and to contribute to the creation of the suborder ?LAC? in SiBCS. The toposequence located in the municipality of Itamarandiba, MG, is inserted in the Jequitinhonha Plateau, in areas known as tableland, elaborated on rocks of the Maca?bas Group, with climate Aw second Koppen classification.The native vegetation is the Cerrado, however, in the area in study the reforestation prevails with Eucaliptus spp. The profiles occupy the following positions of the slope: top (P18) - Rhodic Haplustox, medium third (P25) - Typic Haplustox, lower third (P19) - Typic Haplustox and foot slope (P20) - "LAC". These profiles were described and collected to carry out the characterization proposal. The chemical and physical analyses of routine were accomplished. The total amount of Fe, Ti, Al, Mn and Si was determined for the attack sulfuric and the Fe oxides, Al and Mn were appraised in the dithionite-citrate-bicarbonate extracts and oxalate. The mineralogy was identified by the x-ray diffraction and the Fe oxides were identified for the differential x-ray diffraction. For fluorescence spectrometry X-ray they were certain Ti, Ga e Zr. All the soils presented morphological, physical, chemical and mineralogical typical attributes of the class Oxisol. P20 presented gray color, fragments of massive structure significant, characteristic of Entisol in horizons A and BA. All profiles are clay, distrophic, with low levels of available P and pH around 5. The Fe oxides, in general, reflected the color of the soil and decreased along the slope. The decrease of crystalline Fe and low crystallinity along the slope confirmed the loss of Fe. The Si followed the other way and Al total remained constant. The decrease of relationship Fe2O3/TiO2 indicated in P20 drainage problems in this soil. The mineralogy of clay in all the profiles it is dominated by kaolinite and gibbsite. In P18 were identified hematite and goethite, in P25 hematite with low intensity and goethite, in P19 goethite and in P20 were not identified Fe oxides. The micromorphology showed the prevalence of granular microstructure and packing voids, typical of Oxisol, P18, P25 and P19. In P20 about 25% of the area of the blade the horizon A/BA is composed of the massive microstructure of gray color and 45% is formed by granular microstructure, being this, Bw predominant. The formation of Oxisol of the studied toposequence it can be related with the evolution of the drainage net and for action of the fauna the feralitization prevailed in the formation of " LAC ". The attributes of soil toposequence converge to a single class of soil, the Oxisol, which originated from the same parent material. The ?LAC? had all the attributes necessary for to be included in the class of Oxisol, except the color gray.
