WATER USE IN IRRIGATED AGRICULTURE: AN APPROACH TO WATER PRODUCTIVITY IN DRIP AND SPRINKLER SYSTEMS - DOI: 10.7127/rbai.v11n500747

Resumo

Irrigation plays an important role in agriculture and the increase in the irrigated area and scarce water resources have encouraged the use of irrigation systems and management systems that increase the efficiency of water use. Thus, maximize water productivity has been one of the most important challenges in agriculture. The present study aimed to relate information on water productivity for two irrigation systems, drip and sprinkler systems, with the purpose of understanding the characteristics of these systems and contributing to the advancement of studies and research carried out in the area. Technological innovations aimed at reducing consumption and increasing water productivity through improved water management practices have had limited impact and still need to be adopted on a large scale. It should be emphasized that future research and studies should focus on strengthening the relationships between yield and water consumption to improve productivity. In addition, the techniques and technologies to be deployed in the field must be preceded by a cost analysis for each specific situation in order to verify the economic viability of its adoption.
