Resumo
Through the debate on the efficient use of water in different irrigation techniques, it is necessary to collect information that provides an understanding of the efficient use of this resource when intended for water supplementation of plants. In the southern region of the state of Espírito Santo, citrus and coffee growing are among the main activities that, when irrigated, require information about the performance of the implemented irrigation system. In this sense, the objective of developing this study was to evaluate the efficiency and knowledge of irrigation management in Localized Irrigation systems in conilon coffee and citrus crops in the southern region of the state of Espírito Santo. For the development of this study, irrigation projects already implemented in the municipalities of Alegre, Jerônimo Monteiro and Muqui were used. In the selected projects, the flow rate, uniformity and distribution of water in the systems were determined. Through the flow rate data, the Christiansen Uniformity Coefficient, the Statistical Uniformity Coefficient and the Emission Uniformity Coefficient were determined. In conjunction with the aforementioned tests, interviews were conducted with farmers, which assessed their basic knowledge about irrigation management. The results obtained allowed us to conclude that 75% of the irrigation systems evaluated have a Christiansen Uniformity Coefficient below 90% and only 25% of the systems evaluated have a Statistical Uniformity Coefficient above 84%. Through the interviews conducted, it is possible to state that the interviewees have different understandings and applications regarding irrigation management, which reinforces the need to implement technical training for this audience
