GONZALEZ ROBAINA, Felicita; CISNEROS ZAYAS, Enrique  e  CHATERLAN DURRUTHY, Yoima. Irrigation Management to Reduce Negative Environmental Impacts. Rev Cie Téc Agr [online]. 2023, vol.32, n.1  Epub 09-Dez-2022. ISSN 2071-0054.

Historically, efforts to improve efficiency in the use of water and energy have been carried out separately. Güira de Melena Municipality is located on an underground aquifer open to the sea where the phenomenon of saline intrusion is present. That is why the work aims to show the importance of irrigation programming in water and energy consumption as a measure to mitigate environmental damage. For the study, different farms that planted potatoes under electric central pivot machines were evaluated, where irrigation was carried out using the "Irrigation Forecast" tool. In addition, the influence of said forecast on energy consumption was evaluated following the Energy Audit protocol, all of which was compared with the irrigation management carried out by the Municipal Agricultural Company. The results revealed that irrigation programming through the tool in the evaluated entities was effective in reducing the volumes of water consumed by 23% on average and energy by 8.8% with respect to the current consumption of the company, which emphasizes the need for proper irrigation management as an action to reduce environmental damage.

Palavras-chave : Irrigation Forecast; Central Pivot; Energy Efficiency.
