Abstract.The sugar beet seed production is currently employing a non-planting-and-transplant technology with the use of steklings. Planting units of the machines available on the market feature a number of drawbacks: low productivity, possible injuring of root crops, and increased labor intensity of operators. (Research purpose) To develop a universal design and parameters of an increased-productivity unit for planting steklings of sugar beet and other root crops. (Materials and methods) The design scheme and type of a planting unit have been chosen according to the requirements of applicability and versatility. Its preferred design parameters have been calculated as well. A prototype machine with a universal planting unit in the form of a cellular disk has been developed and manufactured in test production. (Results and discussion) The conducted field experiments proved the versatility of a planting machine with a disc-type unit used for planting root crops, including dimensional characteristics corresponding to those of steklings. The authors have found that when replacing a disk with a different number of cells of different sizes, the machine is suitable for planting a number of similar crops. A removable disk with 12-16 cells has been installed, with its angular speed decreased to 0.393-1.180 radian per second, which is lower as compared to the existing machines. Satisfactory agrotechnical tolerances have been provided for carrot planting in the soil at a depth of 12 cm, a step of 30 cm, and a deviation from the vertical of 110. The intensity of root crop laying in the cells of a seeding disk has been increased to 1-3 pcs. per second. (Conclusions) It has been found that the machine and the planting unit can increase the working speed up to 1.0 meter per second and reduce the labor intensity of operators to the level of safety requirements. The use of universal machines in the breeding and seed production of root crops will reduce the range of the applied machines and operating costs of farm enterprises.

AbstractFor seed production of sugar and fodder beet, the creation of machines and working bodies for planting root crops on testes and pollinators is of current importance. It was found out that the seed-and-water production was spreading with the use of “schteklings” [sugar beet roots]. In the countries with minus temperatures between the vegetation seasons it is necessary to dig out beets and plant them again at the beginning of the vegetation season. Advantages and disadvantages of machines and apparatus for disembarking the schteklings were determined. Under the conditions of applicability, we chose a design scheme and a type of landing gear. With the use of mathematical expressions and standards for the labor intensity of the operator of the above machine, the optimal parameters of its planting apparatus were determined. It was determined that the work of the operator of the schteklings planting machine’s stem will meet the safety standards for the intensity of labor if the planting unit of this machine is a rotor-type. It should be equipped with planting cones and a charging device, a conveyor type. The number of holders of landing cones should be 6-8 pieces, and the radius of the rotor is within the range of 0.344 ... 0.382 m. Such a scheme, type and parameters of the landing gear will allow operators to work at the speed of the planter of up to 1.2 m·s−1.

Eucalyptus has a significant importance for agribusiness forestry Brazil, in relation to GDP (gross domestic product) it participates with about 4%. Among the sectors that require more wood stand out furniture industry and paper and pulp industries experiencing changes in its production base due to legal requirements and marketing. For these reasons, the forest companies have been increasing their interest in gaining certifications that endorse on your requirements related to cultural practices and / or safety and health as FSC (Forest Stewardship Council) 18000 and OSHA (Occupational Safety and Health Administration). Thus, they increase their investments in ergonomics guaranteeing market share, adding value to their products, reducing costs and absenteeism and industrial diseases consequent increase in productivity. In view ergonomic, preservation health worker, allied to technological mechanization, can produce significant increases in production. Thus, the objective is to this work is to develop a hydraulic motocoveador for planting forest species, which meets safety standards in Brazil work and meets the ergonomic conditions, to preserve the health, improved comfort, safety, welfare and increased efficiency of workers. The development of the prototype motocoveador hydraulics was conducted in two stages: the first an appraisal of the main parameters for defining requirements that it must meet, and the second was with the assessment ergonomic operation with the final version of the prototype, conducted in four different slopes of soil. For the evaluation of the prototype was used an area belonging to the Universidade Federal de Viçosa - UFV, located in the city of Viçosa, MG, determining soil moisture between 18.7 and 20.9%. The prototype has 15 kg (with the auger drilling) and its dimensions were determined by means of percentiles (95%) of anthropometric measurements of a sample of operators responsible by pitting for eucalyptus plantation. The evaluation of physical load of work was performed by cardiac monitoring for determination of cardiac load, and the operation of the machine considered mild by this methodology. Biomechanical analysis was performed by simulating the posture and its operation weight of the machine through the software 3DSSPP University of Michigan, having shown that in only one posture the maximum compression in L4/L5 intervertebral disc was exceeded. Noise levels were evaluated using a digital decibel meter positioned near the channel hearing of the operator, indicating average values of noise around 76 dB (A) below the ceiling for a day of eight hours daily work. The collection of vibration levels were performed using a digital accelerometer and compared with the European norm (maximum of 5 m s-2 for 8 hours of work). However, the measured values were between 6.6 and 7.8 m s-2, ie, above the expected. The operational capability effective (Ce) was determined by the timing of completion of each hole in each of the slopes, the Times treated by methodology proposed by Barnes (1977) for determining the mean and thus calculate the Ce, being found from 0.0919 to 0.1093 ha h-1, depending the slope of the ground. Based on these results, the machine developed was efficient for all inclinations analyzed may be a viable alternative to the forestry companies.
O eucalipto tem significativa importância para o agronegócio florestal brasileiro, em relação ao PIB (produto interno bruto) ele participa com cerca de 4%. Entre os setores que mais demandam madeira destacam-se a indústria de móveis e a de papel e celulose, setores que vivenciam alterações em sua base produtiva devido às exigências legais e mercadológicas. Por essas razões, as empresas florestais vêm aumentando o interesse em conquistar certificações que as aprovem em seus requisitos relacionados aos tratos culturais e/ou segurança e saúde como FSC (Forest Stewardship Council) e OSHA 18.000 (Occupational Safety and Health Administration). Dessa forma, aumentam seus investimentos em ergonomia garantindo sua participação no mercado, agregando valor aos seus produtos, reduzindo custos com absenteísmo e doenças laborais e com conseqüente aumento de produtividade. Na visão ergonômica, a preservação da saúde do trabalhador, aliada à evolução tecnológica da mecanização, pode produzir aumentos de produção significativos. Assim, objetiva-se com o presente trabalho desenvolver um motocoveador hidráulico para o plantio de espécies florestais, que atenda às normas brasileiras de segurança de trabalho e cumpra os pressupostos ergonômicos, visando a preservação da saúde, a melhoria do conforto, da segurança, do bemestar e ao aumento da eficiência dos trabalhadores. O desenvolvimento do protótipo do motocoveador hidráulico foi realizado em duas etapas; a primeira consistiu no levantamento dos principais parâmetros para a definição dos requisitos que o mesmo deve atender e, a segunda, se deu com a avaliação ergonômica da operação com a versão final do protótipo, conduzido em quatro diferentes inclinações de solo. Para a avaliação do protótipo foi utilizada uma área pertencente à Universidade Federal de Viçosa UFV, localizada na cidade de Viçosa, MG, sendo determinada a umidade do solo entre 18,7 e 20,9%. O protótipo possui 15 kg (com o trado de perfuração) e suas dimensões foram determinadas por meio de percentis (95%) das medidas antropométricas de uma amostra populacional de operadores responsáveis pelo coveamento para plantio de eucalipto. A avaliação da carga física de trabalho foi realizada pelo monitoramento cardíaco para a determinação da carga cardiovascular, sendo a operação da máquina considerada leve por esta metodologia. A avaliação biomecânica foi realizada por meio de simulação da postura de operação e o respectivo peso da máquina por meio do software 3DSSPP da Universidade de Michigan, tendo mostrado que em apenas uma postura o valor máximo de compressão no disco intervertebral L4/L5 foi ultrapassado. Os níveis de ruído foram avaliados por meio de um decibelímetro digital posicionado perto do canal auditivo do operador, indicando valores médios de ruído em torno de 76 dB(A), abaixo do limite máximo para uma jornada de 8 horas diárias de trabalho. A coleta dos níveis de vibração foram realizadas por meio de um acelerômetro digital e comparados com a norma européia (máximo de 5 m s-2 por 8 horas de trabalho). Entretanto, os valores medidos ficaram entre 6,6 e 7,8 m s-2, ou seja, acima do aceitável. A capacidade operacional efetiva (Ce) foi determinada por meio da cronometragem de realização de cada cova em cada uma das inclinações, os tempos tratados por meio da metodologia proposta por Barnes (1977) para determinação do tempo médio e assim calcular a Ce, sendo encontrado 0,0919 a 0,1093 ha h-1, dependendo da inclinação do solo. Pela análise dos resultados, a máquina desenvolvida se mostrou eficiente para todas as inclinações analisadas, podendo ser uma alternativa viável para as empresas florestais.

Full textAbstract:
Development of a tool for discrete event simulations in forest technology, dependent onspatial components, has successfully been initialized in this thesis project. These simulations may be used to optimize the way the forest is used and to evaluate new machine concepts in forestry. The Python library for discrete event simulation, SimPy, was chosen as the foundationfor the tool. The developed tool can handle spatial objects such as moving machines, trees and boulders. Support for continuous linear movements was also added, which has resulted in a model that partially overlaps continuous and discrete event simulations without any additional computational costs. The result is simulations of a forest with machines operating in it. Two pilot simulations,one of a thinning machine and one of a planting machine, were performed with useful results. The new simulation tool shows promising properties. Limitations and improvements arediscussed, with the conclusion that continued development is recommended.I det här examensarbetet har ett verktyg för diskret event simuleringar inom skogsteknikutvecklats. Sådana simuleringar kan användas för att optimera arbete inom skogsbruk samtför att utvärdera nya maskintekniska koncept. Programmeringsspråket Pythons bibliotek för diskret event simulering, SimPy, valdessom grund för verktyget. Det utvecklade verktyget kan hantera spatiala objekt såsom träd,stenar och stubbar. Stöd för kontinuerliga rörelser har även utvecklats, vilket resulterat i enmodell som delvis överlappar kontinuerliga simuleringar och diskret event simuleringar.Resultatet är kvalitativa simuleringar av skog och skogsmaskiner. Två lyckade simule-ringsstudier har gjorts för Sveriges Lantbruksuniversitet, en simulering av en gallringsmaskinoch en simulering av en planteringsmaskin. Det nya simuleringsverktyget uppvisar lovande egenskaper, även om det har sina be-gränsningar. Fortsatt utveckling av verktyget rekommenderas starkt.

Para o sistema de semeadura direta obter o sucesso desejado deve haver a seleção adequada dos componentes das semeadoras-adubadoras, entre os quais os mecanismos de corte de palha. Além disso, o estudo das características do solo e da cultura de cobertura implantada na área são importantes itens que definem a eficiência destas máquinas. Este trabalho teve como objetivo avaliar o desempenho dos mecanismos de corte de palha de uma semeadora-adubadora em diferentes coberturas vegetais e cargas verticais aplicadas. Para a realização do trabalho foi utilizado um dinamômetro (anel ortogonal), projetado, construído e calibrado numa célula de carga padrão. Os experimentos de campo foram conduzidos na Fazenda Experimental Lageado, pertencente a Faculdade de Ciências Agronômicas - Unesp de Botucatu, durante o ano agrícola de 2005-2006. O delineamento experimental utilizado foi em blocos ao acaso e esquema fatorial 3 x 4, com 4 repetições. Os trabalhos foram realizados com 3 diferentes mecanismos de corte de palha, sendo estes: disco liso (DL), disco corrugado (DC) e disco ondulado (DO), utilizando 4 diferentes cargas verticais, sendo estas: 750 (C1), 1500 (C2), 2250 (C3) e 3000 N (C4). Todos os tratamentos foram instalados em 5 diferentes coberturas de palha: milho, sorgo, aveia preta, triticale e nabiça. Os resultados mostraram que quanto maior a quantidade de matéria seca da cobertura vegetal, maior a demanda de forças horizontal e vertical. Quanto maior a carga vertical aplicada, maior a área de solo mobilizado; maiores são as forças horizontal, vertical e lateral; maior a profundidade de penetração dos discos no solo e menores são a força horizontal por profundidade de corte dos discos (profundidade específica) e a força horizontal por área de solo mobilizado. O disco de corte ondulado possibilita os maiores valores de área de solo mobilizado...

One option for sowing and correct plantability of sorghum is using seeder streaming. With these machines it is possible to perform precise adjustment of the deposition and distribution of seeds and knowledge of its performance in various conditions. In various national regions producing sorghum, there are conditions with steep slopes, thus the plantability seed by seeder-continuous flow may be impaired. Thus, the aim of this study was to evaluate the behavior of the simulator seed deposition by a continuous flow metering system in different conditions of slope, seeding speed and level of the reservoir, as well as assess the quality of seeds deposited. The study was conducted in two stages, the Agrarian Foundation for Agricultural Research - (FAPA) and the Faculty of Agricultural Sciences, UNESP, Botucatu– SP. The first step was the simulation of a seeder streaming operating across the slope, and the second was the analyzes of quality seeds collected in the first stage. The experimental test was being evaluated in randomized factorial design simple by working with three parts (three x three-speed slope, three x three slope reservoir level seed and three x three slope reservoir level seed).Statistical analyzes were performed using SAS software, the data being tested for Tukey and means were compared by F test at 5% level of significance. The results showed that the increase in operating speed reduces the deposition of seeds in the flat slope. The gentle slopes and undulating wavy provide reduction of seed deposition.

Pressupondo-se que os processos de semeadura e colheita da soja possam influenciar os indicadores de qualidade destas operações agrícolas mecanizadas, conduziu-se o presente trabalho na área experimental do Laboratório de Máquinas e Mecanização Agrícola da UNESP/Jaboticabal, com o objetivo de avaliar a qualidade da semeadura e da colheita desta oleaginosa por meio do controle estatístico de processo. A operação de semeadura foi realizada função de três velocidades de avanço (4,7; 6,0 e 9,0 km h-1), com duas populações de plantas (400 e 533 mil plantas ha-1), avaliando-se a força e potência necessárias para o processo, a distribuição longitudinal de plantas na linha de semeadura e as características agronômicas da cultura. Na colheita mecanizada da soja usando ferramentas de controle estatístico, foram avaliadas as perdas quantitativas e a qualidade operacional da colheita. Utilizando os critérios de controle de qualidade a área amostrada constou de 30 pontos especializados, equidistantes em 40 metros, selecionados sequencialmente a partir do início da colheita. Em cada ponto foi determinado altura de corte; umidade dos grãos na colheita; perdas na plataforma, nos mecanismos internos, na deficiência da altura de corte e totais; porcentagem de grãos inteiros e quebrados no graneleiro, na plataforma e no sistema de trilha e limpeza. Os resultados demonstraram que a maior velocidade de semeadura resultou em uma maior demanda de potência média e pico além de menor porcentagem de espaçamentos normais entre plantas.

Each point was determined cutting height; grain moisture at harvest; losses on the platform, internal mechanisms, disability of cutting height and total; percentage of whole and broken grain in bulk, in the platform and track system and cleaning. The results demonstrated that the higher seeding rate resulted in a higher average and peak power demand as well as the lowest percentage of normal spacing between plants. The grain yield was higher in the population initially desired to 533,333 plants ha-1 at the speed of 6 km h-1. The lower operating speed provided less tractor power demand as well the best longitudinal distribution of normal spacing. At harvest ...

Resumo: Realizar mecanicamente a semeadura de soja na população adequada com distribuição de sementes na linha de semeadura de modo eficiente e colhê-la também mecanicamente reduzindo as perdas e quebras dos grãos, ambos são fatores importantes nos processos mecanizados desta cultura para garantir alta produtividade. Pressupondo-se que os processos de semeadura e colheita da soja possam influenciar os indicadores de qualidade destas operações agrícolas mecanizadas, conduziu-se o presente trabalho na área experimental do Laboratório de Máquinas e Mecanização Agrícola da UNESP/Jaboticabal, com o objetivo de avaliar a qualidade da semeadura e da colheita desta oleaginosa por meio do controle estatístico de processo. A operação de semeadura foi realizada função de três velocidades de avanço (4,7; 6,0 e 9,0 km h-1), com duas populações de plantas (400 e 533 mil plantas ha-1), avaliando-se a força e potência necessárias para o processo, a distribuição longitudinal de plantas na linha de semeadura e as características agronômicas da cultura. Na colheita mecanizada da soja usando ferramentas de controle estatístico, foram avaliadas as perdas quantitativas e a qualidade operacional da colheita. Utilizando os critérios de controle de qualidade a área amostrada constou de 30 pontos especializados, equidistantes em 40 metros, selecionados sequencialmente a partir do início da colheita. Em cada ponto foi determinado altura de corte; umidade dos grãos na colheita; perdas na plataforma, nos mecanismos internos, na deficiência da altura de corte e totais; porcentagem de grãos inteiros e quebrados no graneleiro, na plataforma e no sistema de trilha e limpeza. Os resultados demonstraram que a maior velocidade de semeadura resultou em uma maior demanda de potência média e pico além de menor porcentagem de espaçamentos normais entre plantas.

O sistema de produção agrícola exige tecnologias cada vez mais aperfeiçoadas para seu desenvolvimento sustentável, tendo o sistema plantio direto contribuído diretamente nesse sentido, com o aperfeiçoamento de máquinas e equipamentos que melhor se adaptam as suas condições preliminares de implantação. Nesse quadro, as semeadoras-adubadoras são os equipamentos que sofrem as mais variadas modificações em sua constituição, pois nesse sistema o principio básico é o revolvimento somente na linha de semeadura, fazendo com que esses equipamentos realizem operações conjugadas associando qualidade e otimização dos recursos disponíveis. Uma técnica que vem sendo adotada pelos produtores é a substituição (nas semeadoras) dos discos duplos para deposição de adubos pelas hastes sulcadoras em maiores profundidades, com o objetivo de romper as camadas compactadas de solo, adiando assim o uso de escarificadores e subsoladores. Nesse sentido o presente estudo que foi realizado em condições de campo, com o objetivo de comparar dois modelos de hastes sulcadoras, uma comercial e uma experimental, para semeadoras adubadoras de plantio direto, determinado as forças atuantes e os momentos (Fx: força horizontal, Fy: força vertical, Fz: força lateral, My: momento transversal e Fz: momento longitudinal), variando quatro profundidades de trabalho (130mm, 230 mm, 280 mm e 330 mm) com e sem a utilização de disco de corte de palha. A haste Experimental apresentou maiores valores de força horizontal média (Fx), força vertical média (Fy), força lateral média (Fz), força horizontal máxima (Fx max), força vertical máxima (Fy max), força média por área de solo mobilizado (Fx/ASM), força horizontal específica (Fx esp.) momento transversal médio (My), momento longitudinal médio (Mz), momento transversal máximo (My max)...
The agricultural system demands technologies more and more improved for its sustainable development, and agricultural system called no till has been contributed directly in that sense, with the improvement of machines and equipments that could be used with soil previous coverage. In this way row preparation shank are the equipments that suffer the most varied modifications in your constitution, because the basic concept is to revolve only the furrow, so those equipments have to have conjugated operations in consortium with quality and the improvement of the available resources. A technique that has been adopted by the farmers is the change (in the furrow openers) of the double disks for fertilizers deposition for a row preparation shank in higher depths. The objective of this change is to break the compacted layers of soil, postponing the usage of subsoiler and chisel plow witch are more expensive operations. In that sense the present study was accomplish in field conditions, with the objective of comparing two models of preparation shank for no till system, certain the active forcers and moments (Fx: horizontal force, Fy: vertical forces, Fz: lateral force, My: traverse moment and Mz: longitudinal moment), varying four work depths (130 mm, 230 mm, 280 mm and 330 mm) with and without the use of soil and residue cut disk. The experimental row preparation shank showed higher horizontal medium force values (Fx), vertical medium force (Fy), lateral medium force (Fz), horizontal maximum force (Fx max.), horizontal medium force by disturbed soil area (Fx/DSA), horizontal force by soil depth ( Fx sd) transverse medium moment (My), longitudinal medium moment (Mz), transverse maximum moment (My max.), longitudinal maximum moment (Mz max.), mximum power (P max.) e medium power (Pm). The showed differences ( row preparation shank) are related to their building structure. When we worked at... (Complete abstract click electronic access below)

Resumo: As operações agrícolas realizadas de maneira adequada conseguem elevar as produtividades e consequentemente os lucros de uma propriedade. Entre essas operações a semeadura deve receber alto grau de importância, por se tratar da etapa em que se lançam mão dos insumos mais caros da produção, as sementes e o adubo. As semeadoras-adubadoras devem realizar o corte da palhada para a abertura do sulco de semeadura e a deposição das sementes em espaçamentos pré-determinados e a sobreposição correta dessas sementes com solo. Nesse sentido foram realizados três estudos o primeiro com o intuito de avaliar o comportamento dos mecanismos dosadores em função das velocidades de deslocamento por meio do controle estatístico do processo. O segundo, os mecanismos dosadores que se destacaram pela avaliação da qualidade do processo foram avaliados seu comportamento pelo teste de regressão, Já o terceiro buscou-se avaliar o comportamento do mecanismo de abertura do sulco influenciado pelas velocidades analisadas. No primeiro foi possível observar a menor velocidade de trabalho apresentou melhor qualidade, ou seja, menor variabilidade dos indicadores de qualidade monitorados. Para o segundo estudo constatou-se que interação dosador B com as velocidades V1, V2 e V3 apresentaram as maiores populações de plantas e porcentagens de espaçamentos normais, as velocidade superiores influenciaram de maneira significativa esses parâmetros.

Abstract: The operations performed of adequate way can raise yield and consequently the profits of a property. Among these operations sowing should receive a high degree of importance, because it is the stage in which the are used most expensive inputs of the production, seeds and fertilizer. Seeders should perform cutting of the straw to the opening of the sowing groove and the deposition of the seeds at predetermined spacings and the correct overlap of these seeds with soil. In this sense, three studies were carried out in order to evaluate the behavior of the metering mechanisms in function of the displacement speed through the statistical control of the process. The second, the metering mechanisms that highlighted by the evaluation of the quality of the process were evaluated its behavior by the regression test.While the third one sought to evaluate the behavior of the opening mechanism of the groove influenced by the speeds analyzed. In the first one it was possible to observe the lower speed of work presented better quality, that is, lower variability of the quality indicators monitored. For the second study, it was found that the interaction between the doser B and the speeds V1, V2 and V3 showed the highest plant populations and normal spacing percentages, the higher velocities had a significant influence on these parameters. In the third, intermediate speed (9.1 km h-1 ), showed a greater mobilized area and furrow depth, as well as a smaller furrow angle. However, the speed of 6.5 km h-1 presented a larger plant population and productivity. Finally, it is possible to conclude that both the furrow opening mechanism and the seed metering mechanism are influenced by the speed of movement of the tractor-seeder set.

In the cassava production the conventional tillage, characterized by soil preparation with intensive mobilization, is commonly used. However, when this practice results in the maintenance of small quantities of straw on the soil surface, the erosion becomes imminent, and it is exacerbated by the spacing and slow initial development of this culture, especially until four months after planting. An alternative is the no-tillage system, a type of conservation tillage, in which only the owing/planting furrow is prepared for the deployment of culture, and is widely used in soybean, corn, wheat,
beans, and others crops. For cassava, the adoption of this system has raised many questions on the basis of the soil physical properties recommended, according to which the crop requires well-drained and loose soils to allow the proper root development, where the carbohydrates produced by the plant are stored. It is believed that the deployment of a larger soil area in furrow may facilitate the proper development of cassava in no-tillage system and promote the soil protection due the maintenance of straw on the surface. In this context, the objective is improve the furrow opener device of cassava planters using the precepts of the agricultural machinery development process, with the intent of provide the cultivation of cassava in no-tillage system. For the furrow opener development it were implemented the informational, preliminary and detailed design phases of the product development process. It where formulated for the task of preparing the planting furrow, 31 needs of customers who were deployed in 30 customer requirements and then in 27 design requirements. From these requirements and the solutions available on other agricultural machines and implements, the winged tines where selected as a potential
solution. So, a layout study where conducted and resulted in the construction of prototypes with different geometries to experimentation with cassava crop and tests
of forces. The use of the reference model for the development process of agricultural machinery allowed the development of furrow opener device for the cultivation of
cassava in no-tillage system, that have low cost, small number of components, simple manufacturing process and smooth operation. The yield obtained with the cassava crop in conventional tillage and no-tillage was similar, showing that this technique can be used to grow without comNo sistema de produção da mandioca o preparo convencional do solo (intenso revolvimento) é comumente utilizado. Quando esta prática resulta na manutenção de pequenas quantidades de palha sobre o solo, o problema da erosão se torna eminente e é agravado pelo espaçamento entre linhas e o lento desenvolvimento inicial desta cultura, principalmente até os quatro meses após o plantio. Uma alternativa é o sistema plantio direto, em que apenas o sulco de semeadura/plantio é preparado durante a implantação da cultura, e é largamente utilizado nas culturas de soja, milho, trigo, feijão, entre outras. Para a mandioca, a adoção deste sistema tem gerado muitas dúvidas em função das condições físicas do solo recomendadas, segundo as quais a cultura requer solos bem drenados e soltos para possibilitar o adequado desenvolvimento das raízes. Acredita-se que a mobilização de uma maior área de solo no sulco de plantio possa viabilizar o adequado desenvolvimento da mandioca em sistema plantio direto e favorecer a proteção do solo pela manutenção da palha sobre superfície. Nesse contexto, objetivou-se aperfeiçoar o mecanismo sulcador de plantadoras de mandioca utilizando os preceitos do processo de desenvolvimento de máquinas agrícolas, com o intento de viabilizar o cultivo de mandioca em sistema plantio direto. Para o desenvolvimento do mecanismo foram executadas as fases de projeto informacional, preliminar e detalhado. Formularam-se, para a função de preparar o sulco de plantio, 31 necessidades de clientes que foram desdobradas em 30 requisitos de clientes e posteriormente em 27 requisitos de projeto. A partir destes requisitos e das soluções disponíveis em outras máquinas e implementos, selecionou-se a haste sulcadora alada como potencial solução. Desta forma, realizou-se um estudo de leiautes que culminou na construção de protótipos com diferentes geometrias para testes, experimentação com a cultura da mandioca e ensaio de esforços. A utilização do modelo de referência para o processo de desenvolvimento de máquinas agrícolas permitiu o desenvolvimento de uma haste sulcadora alada de baixo custo, pequeno número de componentes, processo de fabricação simples e bom funcionamento. A produtividade obtida com a cultura da mandioca em preparo convencional e sistema plantio direto foi semelhante, evidenciando que esta técnica pode ser utilizada para o cultivo sem comprometer a produtividade e ainda melhorar a sustentabilidade do sistema.

Climate changes play a significant role in the crops plantation process. Such changes affect the suitability of planting of many crops in their traditional plantation dates in a given place. In contrary, many of such crops become more suitable for planting at other new dates in their traditional places or in other new places regarding the climate changes. This chapter presents a fuzzy-based approach for optimizing crops planting dates with the ongoing changes in climate at a given place. The proposed approach incorporates four phases. The first phase is concerned with climate data preparation. And the second phase is concerned with Defining suitability membership functions. While in third phase is responsible for automatic fuzzy clustering. Finally, the fourth phase is responsible for fuzzy selection and optimization for the more suitable plantation dates for each crop. This chapter consists of an introduction, related works, the proposed approach, a first case study, a second case study, results discussion, future research directions and finally the chapter conclusion.

Full textAbstract:
In the deep gravelly soils of the Bordeaux region, Seguin (1972) found vine roots at a depth of 6 m. Woody “framework roots” tend to be at least 30–35 cm below the surface and do not increase in number after the third year from planting (Richards 1983). Nevertheless, smaller diameter “extension roots” continue to grow horizontally and vertically from the main framework. They may extend laterally several meters from the trunk. These roots and finer lateral roots in the zone 10–60 cm deep provide the main absorbing surfaces for the vine. But in soils with a subsoil impediment to root growth, such as many of the duplex soils in southeast Australia (section 1.3.2.1), less than 5% of vine roots may penetrate below 60 cm (Pudney et al. 2001). Nor do vines root deeply in vineyards where irrigation supplies much of the vine’s water in summer. Plant roots and associated mycorrhizae (section 4.7.3.2) help to create soil structure. A desirable soil structure for vines provides optimal water and oxygen availability, which are fundamental for the growth of roots and soil organisms. The structure should be porous and not hard for roots to penetrate, allow ready exchange of gases and the flow of water, resist erosion, be workable over a range of soil water contents, allowing the seedlings of cover crops in vineyards to emerge, and be able to bear the weight of tractors and harvesting machinery with a minimum of compaction. The quality of soil structure and its maintenance in vineyards are discussed further in chapter 7. We might expect the soil particles described in chapter 2 simply to pack down, as happens in a heap of unconsolidated sand at a building site. However, if the sand is mixed with cement and water, and used with bricks, we can construct a building—a solid framework of floors, walls, and ceilings. This structure has internal spaces of different sizes that permit all kinds of human activities. So it is with soil. Vital forces associated with the growth of plants, animals, and microorganisms, and physical forces associated with the change in state of water and its movement act on loose soil particles.

Currently, the reforestation process has a number of disadvantages, such as the need to use manual labor during the distribution and planting of seedlings; mechanisms for planting seedlings are often equipped with tractors as traction means. The creation of furrows and the preparation of the soil immediately before planting affects the energy consumption of the implements’ drives. At the moment, the inefficiency of planting work is high, since the planting of seedlings with a closed root system occurs in conjunction with a plow. All these factors, when calculated for a long-term period, lead to greater energy consumption when carrying out this type of work. This article discusses approaches to the mechanization of the planting process. Using the experience of planting seedlings with a closed root system (CCS) manually and analyzing the methods of mechanization of planting, it is possible to obtain maximum efficiency when carrying out this type of work. Based on the material studied, a prototype of a planting device suitable for the technology of discrete planting of seedlings with ZKS was selected. Solid modeling of the working body in the Solidworks computer-aided design system has been carried out. When designing the model, the possibility of its production using additive technology using the FDM printing method was envisaged.
