Currently there is a range of nitrogen fertilizers, with different commercial names and different concentrations of nitrogen, for this reason the research aims to evaluate the response of rice (Oryza sativa L.) to the application of nitrogen fertilizers in lands subject to flooding. temporary. The randomized complete block design (DBCA) was used with a total of six treatments that includes the absolute control with a total of 4 repetitions. The variables were subjected to the analysis of variance and Duncan's test to establish the statistical significance and difference between the treatments under study. The study consisted of the application of nitrogen fertilizers described below; five treatments (Urea CON2H4, Yaravera amides, ammonium nitrate NH4NO3, ammonium sulfate (NH4)2SO4, producer fertilizer) and an absolute control. The following variables were evaluated; number of tillers per m2 , height from plant to flowering, number of panicles per m2 , percentage of sterility, yield, and economic analysis. Once the results were obtained, it was determined that the applications made with the YaraVera Amidas fertilizer treatment (T2) presented the highest results in the agronomic behavior of the plant with an average of 28 tillers per m2 , a plant height of 66, 80 cm, 30 panicles per m2 and a percentage of 6.89% sterility. The yield obtained with the YaraVera Amidas treatment obtained the highest yield with 7933.16 kg / ha-1 and presented the highest economic gains of $ 303.91 indicating a B / C ratio of 1.17 this reflects that for every dollar invested you get a profit of 0.17 cents with a profitability of 116.53%.
