Para isso foram realizadas medi??es das vaz?es dos gotejadores, em talh?es de caf? com idade de 5 anos. Os gotejadores foram selecionados utilizando-se a metodologia proposta por KELLER & KARMELI. Por meio dos resultados dos c?lculos obtidos a partir dos dados coletados em campo, estimou-se o volume de ?gua aplicado, o consumo de energia real de cada propriedade rural e kg de gr?os produzido por l?mina de ?gua aplicada pelo produtor. Em seguida, com as informa??es da evapotranspira??o real, da evapotranspira??o da cultura, efici?ncia do sistema de irriga??o e Kc da cultura do caf?, determinou-se o volume de ?gua e o consumo de energia el?trica simulados para a condi??o de manejo adequado da irriga??o nas propriedades em estudo, no per?odo de janeiro a julho de 2009. Os resultados obtidos permitiram concluir que, em fun??o da inexist?ncia de um manejo adequado da irriga??o, 75% e 25% das propriedades em estudo apresentaram, respectivamente, aplica??o em excesso e em d?ficit de ?gua. Essa falta de manejo dos sistemas de irriga??o teve implica??o direta no consumo de ?gua, de energia el?trica e de kg de gr?os produzido por mm de ?gua aplicada na cultura do caf? nas propriedades pesquisadas durante o per?odo do estudo.Disserta??o (Mestrado) ?

For that were realized measurements of flow in the leaking system using plots of coffee with 5 years old and the tools were selected using the methodology wich was proposed by KELLER & KARMELI. Through the results obtained from data colecting in field it was possible to the estimate the volume of applied water, energy consumption in each rural property?and kg of grain produced?by water shade. Then, with the information about real evapotranspiration, evapotranspiration of culture, irrigation system efficency and Kc of coffee culture, it was determined water volume and eletric energy consumption simulated?to the condition of adequated irrigation handling in the properties of study from January to July of 2009. In conclusion, the results? showed that due to inexistence of adequated irrigation handling, 75% and 25% of the studied?properties presented, respectively,? use of water in excess and in lack. This lack of handling in the irrigation system had direct inference in water consumption, electric energy and kg of produced grains per mm of applied water in coffee culture in the studied properties during the period of the work
