Resumo: Operational field efficiency in agricultural operations estimates the amount of area not worked due to time consumed in machine preparation, transport of the machine from farmstead to the field and back, inappropriate utilization of the working width, turning time at each end and other interruption during the working day. The operational efficiency in terms of various time components can be expressed in a mathematical model: Ro = [To/(Te + Th + Ta)] x 100. Based on this model, a simpler model has been elaborated for field efficiency relating it to parameters such as speed of operation (V), turning time (T) and time efficiency (Eft), which can be easily measured in the field through sampling. The paper tests this simple model with variation of different independent variables based on literature, and figures obtained during field experimentation, to evaluate the effects of length of run, number of attachment, type of operation and wheeled tool carrier which could affect V, T and Eft.

O rendimento operacional pode ser definido por componentes de tempo, em modelo matemático Ro = [To/(Te + Th + Ta)] x 100. Com base neste modelo, elabora-se outro, mais simples relacionando os parâmetros mensuráveis pela mostragem como velocidade de deslocamento (V), tempo de giro (T) e eficiência de tempo (Eft). Este trabalho testa o modelo simples com variação de diferentes variáveis independentes, com base nas informações existentes na literatura, e os valores encontrados nas experimentações realizadas para avaliar os efeitos de comprimento da parcela, número de implementos usados, tipo de operação e tipo de chassi porta-implementos, que podem efetuar os valores de V, T e Eft.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraLal, Harbans2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15328Pesquisa Agropecuaria Brasileira; v.18, n.6, jun. 1983; 649-656Pesquisa Agropecuária Brasileira; v.18, n.6, jun. 1983; 649-6561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15328/9180info:eu-repo/semantics/openAccess2014-04-16T18:59:25Zoai:ojs.seer.sct.embrapa.br:article/15328Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:59:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
