39. PARÂMETROS MECÂNICOS DE TRAÇÃO EM SISTEMAS DE CULTIVO DE MELANCIA / MECHANICAL PARAMETERS OF TRACTION IN WATERMELON CROP SYSTEMS
No Rio Grande do Sul, a melancia é cultivada em uma grande área de solos arenosos, onde o preparo convencional do solo é o mais utilizado, favorecendo a erosão hídrica. Isto leva as áreas sob cultivo desta hortaliça a processos erosivos intensos, onde em alguns casos ao final do cultivo, as áreas tornam-se impróprias para cultivos posteriores. Com o

40. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

41. Protocolo ISO 11783: procedimentos para comunicação serial de dados do controlador de tarefa / ISO 11783 protocol: procedures for serial data communication with the task controller
The recent growth of automation technology and embedded electronic in agricultural machinery has established a new practice in agriculture. These new practices related to precision agriculture (PA) have demanded the use of sensors and communications embedded networks for data acquisition and control devices in the farm field. The incompatibility between hard

43. Strategy on agribusiness chains as a tool to estimulate regional development: proposition of an analysis model, and its aplication on soybean chanin in Toledo (PR) / EstratÃgia nas cadeias do agronegÃcio como ferramenta indutora do desenvolvimento regional: proposiÃÃo de modelo de anÃlise e aplicaÃÃo na cadeia da soja em Toledo (PR)
This study analyses strategically the regional development together with the economical viability subject. An analysis model is proposed, inspired on SWOT and BCG matricial analysis, bringing concenpts from business strategy, creating tolls based on a theorical structure about regional development and economical viability analysis. This model is applied on s

44. Evaluation of boom hydraulic sprayers in the region of Uberlândia-MG / Avaliação de pulverizadores hidráulicos de barra na região de Uberlândia-MG
Any and every manner of pesticide application represents environmental risks, which must be minimized by the use of proper knowledge and technology, assuring a sustainable food production. Often, great importance is given to the pesticide and little to the application technique. The identification of the conservation state and mode of use of the sprayers in

45. Atributos biológicos e químicos de um solo cultivado com cana-de-açúcar (Saccharum officinarum L.) fertirrigado com vinhaça / Biological and Chemical Attributes of a Soil Cultivated with Sugar-cane (Saccharum officinarum spp) fertirrigated with vinasse.
The agriculture has come to pass by big changes that include the introduction of synthetic chemical products, the use of more refined machinery, the diminution of the diversification of cultures and the emergency of more specialized and large-scale producers. Consequently, in the evolution of the man and the environment relation, the environmental imbalances
