This research was 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 2017-I. The main of this project was to evaluate the responses in grain yield between interaction of nitrogen levels and irrigation methods in rice crop in direct sowing. The irrigation methods used were: continuous flood irrigation and intermittent flood irrigation. The nitrogen levels were: 0. 240 and 360 Kg N ha-1 . The experimental design used for this work was Split Plot design with 4 replicates. The cultivar was used IR-43. The results showed that there were no statistical differences in grain yield, between the irrigation methods used neither between the interaction of both factors under study. Nitrogen levels significantly increased grain yield. Water consumption was 10874 m3 ha-1 , for continuous flooding and 7510 m3 ha-1 for intermittent flood irrigation. Water productivity of 30.94% higher was obtained in the intermittent flood irrigation method compared to continuous flood irrigation. The maximum yield (10.06 t ha-1 ) and dry matter (21.5 t ha-1 ) was obtained with the level 360 Kg N ha-1 . In the harvest index no statistical differences were obtained in both irrigation method and nitrogen levels. There were no statistical significance among the agronomic, physiological efficiency and partial productivity for irrigation methods, obtaining average values of 23.03 Kg of rice produced per Kg of N applied, 34.23 Kg of rice produced per Kg N accumulated and 35.13 Kg of rice produced per Kg of N applied respectively, and between levels 240 and 360 Kg N ha-1 there was a significant difference between both levels for agronomic efficiency and partial productivity with values between 27.19 and 18.86 Kg of rice produced per Kg of applied N and 41.72 and 28.54 Kg of rice produced per Kg N accumulated respectively, while for physiological efficiency levels 240 and 360 Kg N ha-1 have no significant difference with the values 36.98 and 31.48 Kg of rice produced per Kg of N applied respectively.
