Resumo
O conhecimento da produção e dispêndio de energia pela agricultura é fundamental devido à importância estratégica que ocupa como produtora de insumos energéticos para outros setores econômicos, como é o caso do biodiesel produzido a partir de culturas oleaginosas; desta forma o presente estudo teve como objetivo determinar os custos parciais da implantação e condução do agroecossistema milho em consórcio com pinhãomanso, sob três diferentes sistemas de condução (sequeiro, irrigado e fertirrigado com água residuária da suinocultura) do ponto de vista energético e econômico, em experimento conduzido de acordo com o sistema produtivo da agricultura familiar da região oeste do Paraná. Tal estudo se justifica devido à escassez de dados tanto energéticos como econômicos da cultura do pinhão-manso em condições brasileiras, bem como em sistema consorciado sob condições tecnológicas da agricultura familiar do oeste paranaense e, sobretudo das questões ambientais envolvidas neste estudo como o reuso de águas e o uso racional de fontes energéticas não-renováveis. O experimento foi conduzido de acordo com as técnicas empregadas por agricultores familiares da região oeste paranaense, no período de fevereiro de 2008 a maio de 2008 para a cultura do milho e de fevereiro de 2008 a novembro de 2009, para a cultura do pinhão-manso, no Núcleo Experimental de Engenharia Agrícola (NEEA), pertencente à Universidade Estadual do Oeste do Paraná (UNIOESTE), campus de Cascavel/PR...
Knowledge of production and energy expenditure in agriculture is crucial due to strategic importance which occupies as a producer of energy inputs to other economic sectors, such as biodiesel produced from oilseed crops, so this study aimed to determine partial costs of deployment and conduct of corn intercropping agroecosystem with physic nut, under three different management systems (rainfed, irrigated and fertirrigated with wastewater from pig farming) in terms of energy and economic experiment carried out in accordance with the productive system of family farming in the west of Paraná. Such a study is justified due to the shortage of both energy and economic data of the culture of physic nut under Brazilian conditions, as well as in intercropping system under technological conditions of the family farm west of Paraná, and especially environmental issues involved in this study as the reuse of water and the rational use of nonrenewable energy sources. The experiment was conducted in accordance with the techniques employed by farmers in the region, from February 2008 to May 2008 for corn and from February 2008 to November 2009 for the cultivation of physic nut in Experimental Center of Agricultural Engineering (NEEA), belonging to the State University of West Paraná (UNIOESTE), campus of Cascavel/PR, in the area of no-tillage. The itinerary for all technical training systems consisted of: the site preparation (application of desiccant), mechanized planting of corn, corn plant by hand, production of seedlings of physic nut, coveamento and transplant seedlings of physic nut, mowing manual, manual application of insecticide and harvesting of maize, differing only by irrigation and fertirrigation. The final product was assessed only corn. The technical coefficients, the workload, performance, identification of the tractor... (Complete abstract click electronic access below)
