Rice production has a great significance in Peru´s basic diet. One of the big challenges of rice production is to improve water saving while optimizing yield. Alternate Wetting and Drying (AWD) is an irrigation practice that consists on reducing water consumption by alternating dry and wet cycles on irrigation. In this work; carried out at the Vista Florida Experimental Station of the Instituto Nacional de Innovación Agraria - INIA (National Institute of Agrarian Innovation), Lambayeque, during the growing season of 2020 – 2021; the objectives stablished were to contribute to water saving rice production and to analyze the effect of AWD in rice growth and yield. We evaluated three irrigation treatments: (1) continuous flooding (CF), (2) AWD with 5 cm of field water level below the surface and (3) AWD with 10 cm of field water level below de surface. Overall, continuous flooding system had the highest yield compared to both AWD systems, reaching 8.7 t/ha; yet the AWD – 5 cm treatment reduced water consumption in 10.9% and managed to obtain 87% of CF yield. Number of tillers formed per square meter and the number of panicles formed per square meter were most the variables most affected by AWD treatments. On the other hand, water productivity was the same on the three systems as no difference were observed. We concluded that, with our current conditions in production, Alternate Wetting and Drying is a promising technique that can save water usage and more research needs to be done in order to minimize yield reduction.
