Abstract: The region of Campinas is one of the largest producer of fresh market tomatoes in Brazil. However, the furrow irrigation system usually adopted by the farmers is known by its high water consumption; due to lack of water management and to its distribution in bare soil open channels. In order to identify the major causes of water loss, a furrow irrigation system traditionally employed in the region was evaluated. The following irrigation performance parameters were determined under field conditions: water application efficiency, storage efficiency, deficit degree, runoff and deep percolation losses. Additionally, the water use efficiency was evaluated at the end of the crop cycle. Based on the obtained results, it was observed that the values of application efficiency were between 25.3 and 32.2%, with deep percolation losses between 62.3 and 74.1%. The values of the irrigation performance parameters demonstrated that the adopted irrigation management provides low values of application efficiency, mainly due to high losses by percolation. These results showed that farmers need to implement some technical criteria to manage the irrigation practices and search for technological changes in the water distribution systems.
