This thesis project entitled "Dispersion Analysis of the concentration of N03- by the Rice activity in the Indoche river, Moyobamba tier - Yantalo, 2013", is about the development of a study of the dispersion of the compound nitrate (N03-) in a final stretch of5 km ofthe river Indoche until its mouth the River may. The study area ofthe project covers an area of 312.24 hectares. The jurisdiction to which belongs the project area, corresponds to the Moyobamba district and province, San Martin region. The watershed to which belongs the project area, is the basin of the Indoche river (that has an extension of 54,364.68 ha), representing the study area, the 0.57 % of the total area of the basin. In the study area, the predominant crop is rice, occupying approximately 4 7% of the study area. According to INFOAGRO (www.infoagro.com), mentions that the subscriber for the cultivation of rice is performed in two phases: the first as a subscriber of fund and, second, at the beginning of the reproductive cycle. Also, it affirms that the whole-body dose for the cultivation of rice is 150 kg of nitro gen per hectare distributed two times (75 % as fund compost and 25 % to the initiation of the panicle ). On the other hand, the design developed for the data collection, it was determined ten samples with their respective location coordinates, and in turn separated to 500 m. Through the Kit for nitrates (100 tests), which is a computer that contains: a cup of glass, to collect the water sample; a tube gauge, to match colors with that of the sample; and packages of the reagent HI 3874-0 which contain granules of cadmium to perform the chemical reaction; it was determined the concentrations for each sampling point, resulting in average low levels from 3 .1 to 5 mg/L or ppm in the stretch of 5 Km. The method that performs this equipment (Kit for ni trate) is the colorimetric, which is based on quantifying or obtain numeric values from color. Finally, the dispersion analysis ofthe N03-, took their respective study, through the use of correlation, which is a statistical model for assessing the degree of relationship that exists between two values, and that furthermore, determines the behavior using the regression line, either ascending or descending.
