In setting up the experiment, the seedlings were separated by size: smaller, medium-sized and larger, so that the implementation of the orchard, there was within each block seedlings with similar vigor. The seedlings of papaya (Carica papaya L.) were prepared, using seeds of papayas hermaphrodites of the cultivar ' Golden Sunrise ', belonging to the soil. On planting and leading between each block, was grown legumes Sunn hemp (Crotalaria juncea) as green manure. The plants were bi-monthly composted manure tanned and potassium sulphate and alternating sprays with foliar fertilizer Agrobio (2%). The phytosanitary control followed the rules of organic farming. Spontaneous herbs were controlled by means of plant cover (Sunn hemp biomass) and periodic ro?adas. It took the experimental design of randomized blocks, being arranged in factorial arrangement of treatments. We evaluated the whole milk concentrations (0,0%, 5% and 10%) + 1% Bordeaux mixture (subplots), in six different breeding densities (1667, 2167, 3167, 2667, 3667 and 4167 plants. hectare-1). Based on the results it is concluded that: the addition of raw cow's milk to the Bordeaux mixture enables greater control of smallpox of papaya, both on the leaves, as in the fruits; the mixture prepared with 10% of raw cow's milk in Bordeaux mixture, the greater the inhibition signs of smallpox from papaya, both on the leaves, as in the fruits; analyzing by vegetative aspect of papaya, the greatest effect of the addition of raw cow's milk in Bordeaux mixture occurs in younger leaves; the extent to which increasing the dosage raw cow's milk, from zero to 10%, in Bordeaux, increases linearly, the ability to control the smallpox of the papaya, both on the leaves, as in the fruits; less degradated plantations allow lower occurrence of smallpox from papaya, both on the leaves, as in the fruits, if compared to those more Caterpillar; the density of plantation of papaya of 1667 plants.ha-4167 plants even 1.ha-1 the severity of smallpox of the papaya tree increases in a linear fashion; smallpox papaya progresses, exponentially, from bottom to top and/or older leaves to the newest; the part of the fruit, stuck in the plant, yet more exposed to external factors, is the most affected by smallpox of papaya, compared with the part facing the stem; analyzing for the papaya reproductive aspect, the greatest effect of the addition of raw cow's milk in Bordeaux is noticed on the face less exposed of the fruit; and, eat avocado with more leaves infected by smallpox will produce fruits also more affected by this disease / O estudo foi conduzido, no Centro Estadual Integrado de Educa??o Rural ? CEIER, situado no munic?pio de ?guia Branca, Regi?o Noroeste do Estado do Esp?rito Santo, o objetivo deste trabalho foi avaliar a a??o do leite integral adicionado ? calda bordalesa no controle do Asperisporium caricae, agente causal da var?ola e o comportamento desta doen?a em diferentes densidades de cultivo do mamoeiro. Na montagem do experimento, as mudas foram separadas por tamanho: menores, m?dias e maiores, de forma que na implanta??o do pomar, houvesse dentro de cada bloco mudas com padr?o de vigor parecido. As mudas de mamoeiro (Carica papaya L.) foram preparadas, utilizando-se sementes de mam?es hermafroditas da cultivar ?Sunrise Golden?, pertencente ao grupo Solo. Na entrelinha de plantio e entre cada bloco, foi cultivada a leguminosa crotal?ria (Crotalaria juncea) como adubo verde. As plantas foram bimensalmente adubadas com esterco curtido e sulfato de pot?ssio e pulveriza??es alternadas, com o biofertilizante l?quido Agrobio (2%). O controle fitossanit?rio seguiu as normas da agricultura org?nica. As ervas espont?neas foram controladas por meio de cobertura vegetal (biomassa da crotal?ria) e de ro?adas peri?dicas. Adotou-se o delineamento experimental de blocos ao acaso, sendo os tratamentos dispostos em parcelas subdivididas. Avaliaram-se as concentra??es de leite integral (0,0%, 5% e 10%) + calda bordalesa 1% (subparcelas), dentro de seis densidades de cultivo diferentes (1667, 2167, 2667, 3167, 3667 e 4167 plantas.hectare-1). Com base nos resultados conclui-se que: a adi??o de leite de vaca cru ? calda bordalesa possibilita maior capacidade de controle da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; a mistura preparada com 10% de leite de vaca cru na calda bordalesa, propiciou a maior inibi??o dos sinais da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; analisando pelo aspecto vegetativo do mamoeiro, o maior efeito da adi??o do leite de vaca cru na calda bordalesa ocorre nas folhas mais novas; a medida em que se aumenta a dosagem de leite de vaca cru, de zero at? 10%, na calda bordalesa, aumenta-se, linearmente, a capacidade de controle da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; plantios menos adensados possibilitam menor ocorr?ncia da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos, se comparados ?queles mais adensados; da densidade de plantio do mamoeiro de 1667 plantas.ha-1 at? 4167 plantas.ha-1 a severidade da var?ola do mamoeiro aumenta de maneira linear; a var?ola do mamoeiro progride, exponencialmente, de baixo para cima e/ou das folhas mais velhas para as mais novas; a parte do fruto, preso ainda na planta, mais exposta aos fatores externos, ? a mais acometida pela var?ola do mamoeiro, se comparado com a parte voltada para o caule da mesma; analisando pelo aspecto reprodutivo do mamoeiro, o maior efeito da adi??o do leite de vaca cru na calda bordalesa ? notado na face menos exposta do fruto; e, mamoeiros com as folhas mais infectadas pela var?ola produzir?o frutos tamb?m mais acometidos por esta doen?a.

The theme of my work is central stocking. My work is dealing with central stocking on the basis of literary sources in theory. On account of theoretical prepared structure it analyses central stocking in two manufacturing corporation which are settled in Czech Republic and pursue a comparison of gained outcomes. In theoretical part is stocking included in broader framework of whole problems of organization. Also are supposed thesis of the importance and character of execution of stocking compared to its costs, central stocking is determinate (beside not central) and its main competence are more closely explained. Central stocking is analyses in bigger detail by processing access which is inspired by a structure of the process according to ISO 9001. A separate range and content of central stocking is translated in light of stocking equipment and stocking processes. In practical part two companies were analyzed and compared in particular regard. By this was given knowledge of the single stocking systems and thanks to that coherent knowledge their conformity and contrasts. In the part of discussion are claimed the most significant common ascertained agreements and differences and the most important references are made in relation to surveyed stocking systems. A conclusion of my work summarizes principal differences which were found in profession part of stocking systems of compared subjects and resumes the need of harmonization of all coherent component of the system.

In this sense, integrated crop-livestock systems have been characterized by different dynamics compared to conventional crops systems, mainly because of the more efficient use of inputs due to high nutrient stored in the soil. The no-tillage (NT) associated with integrated crop-livestock (ICL) has been an alternative for intensification of soil use in Southern Brazil. In this issue, there are a lot of farmers have been cropped maize for silage production in the summer and annual ryegrass for various purposes (cover crop and animal feed). The maize due its yield potential, chemical composition and nutritional value, among other factors, constitutes one of the most important cropped and consumed cereal in the world and, moreover, this crop can be used for market manufacturing animal feed and human food. In this work were (i) evaluate the effects of liming on soil management systems (conventional tillage – CT, minimum tillage – MT, no-tillage – NT, and chiseled no-tillage – CNT) about the accumulated nutrients in maize aerial part; (ii) evaluated the dry matter (DM) and silage yields taking into consideration the previous crop annual ryegrass for different uses (cover crop – C, grazing – G, and silage – S) during the winter. The experiment was carried out Field Demonstration and Experimental (CDE) of the ABC Foundation, in the municipality of Castro-PR, in a clayey Haplohumox. The experimental design was a randomized complete block with split plots and four replications. In main plots (10 x 30 m), four systems of soil management (CT, MT, NT and CNT) was studied. In subplots (10 x 10 m), the annual ryegrass was cropped for different purposes (C, G and S). The intensification of soil use due pasture or silage production during the winter cannot change macronutrient inputs in systems of soil tillage under high concentration of organic matter and acidity controlled. This can be state if the winter pasture to be adequately managed. The high DM and macronutrients accumulated in aerial part of maize show the ability of annual ryegrass for nutrient recycling on the systems of production with different tillage and conditions of lime reactivity. / Pesquisas vêm sendo direcionadas no sentido de aprimorar a eficiência de utilização de nutrientes pelas plantas, evitar a degradação dos recursos ambientais, aumentar o rendimento das culturas e maximizar a lucratividade no sistema de produção agrícola. Nesse sentido, os sistemas integrados de produção têm sido caracterizados por dinâmica diferenciada em relação aos cultivos isolados, principalmente por apresentarem maior eficiência na utilização dos insumos. O sistema plantio direto (SPD), aliado à integração lavoura-pecuária (ILP) tem se destacado como uma das alternativas para a produção mais intensiva e sustentável de alimentos no Sul do Brasil. Nesse caso, o milho tem sido cultivado em sucessão ao azevém anual que pode ser destinado na forma de pastejo e/ou silagem pré-secada consumida pelos animais e também como cobertura do solo. O milho por seu potencial produtivo, sua composição química e seu valor nutritivo, entre outros fatores, constituí em um dos mais importantes cereais cultivados e consumidos no mundo, assumindo grande importância em âmbito mundial devido a suas inúmeras finalidades, como atender ao mercado de fabricação de ração animal e alimentação humana. Os objetivos deste trabalho foram: (i) avaliar os efeitos da calagem em sistemas de manejo do solo (sistema convencional – SC, cultivo mínimo – CM, sistema plantio direto – SPD, e SPD com subsolagem – SPD+S) sobre o acúmulo de macronutrientes na parte aérea do milho; (ii) avaliar o rendimento de massa seca/silagem, decorrente de diferentes formas de uso (planta de cobertura do solo, pastejo animal e produção de silagem) do azevém anual durante o inverno. O experimento foi instalado no Campo Demonstrativo e Experimental (CDE) da Fundação ABC, no município de Castro, PR, em um solo Latossolo Bruno argiloso. O delineamento experimental utilizado foi o de blocos completos casualizados, com parcelas subdivididas e quatro repetições. Nas parcelas (10 x 30 m) foram estudados quatro sistemas de manejo do solo (SC, CM, SPD e SPD+S). Nas subparcelas (10 x 10 m) foram estudadas três formas de uso do azevém anual (cobertura, pastejo e silagem). A intensificação de uso do azevém anual mediante pastejo ou silagem pré-secada, desde que leve em consideração os critérios de altura (para pastejo/corte e resíduo) e nutricionais (com base na exportação e rendimento de massa seca) não alteram os aportes dos macronutrientes em sistemas de preparo de solo com alto teor de MO e acidez corrigida. Os altos rendimentos de MS e acúmulos de macronutrientes na parte aérea do milho evidenciam a capacidade do azevém anual proporcionar a reciclagem de nutrientes no sistema de produção, independentemente do manejo de solo adotado e condições de reatividade do calcário.
