| description | There are irrigation evaluating uniformity methods, where the hydraulic operating conditions of the irrigation system and its influence on the water requirements of a crop are estimated. The evaluation methodology used in this research was the polynomial model, The study evaluated the functioning of the irrigation system with 4 different operating pressures, which were measured at the irrigation valve module exit, for each operating pressure 16 flow data were collected on 5 irrigation modules using a Nelson R10 self-compensating sprinkler.The results of the research were: the uniformity coefficient, the distribution coefficient, the properly irrigated area and the irrigation suitability factor. One of the main results was the absence of significant difference between the pressures while they are in the range of auto compensation. On the other hand the distribution coefficient shows that there are significant differences between treatments, although all give values greater than 90%, in contrast to the relative percentages of a properly irrigated area that does not exceed 50 °/0 in any of the treatments, It was validated and verified that the se|f—compensating installed sprinkler Nelson R10 complies with the technical operating characteristics exposed in the catalog of the manufacturer (self-compensating pressures and uniformity), however, the irrigation depth applied must be managed and controlled. |

Aspersor autocompensado Modelo polinomial Coeficiente de Uniformidad Riego Lámina de agua There are irrigation evaluating uniformity methods, where the hydraulic operating conditions of the irrigation system and its influence on the water requirements of a crop are estimated. The evaluation methodology used in this research was the polynomial model, The study evaluated the functioning of the irrigation system with 4 different operating pressures, which were measured at the irrigation valve module exit, for each operating pressure 16 flow data were collected on 5 irrigation modules using a Nelson R10 self-compensating sprinkler.The results of the research were: the uniformity coefficient, the distribution coefficient, the properly irrigated area and the irrigation suitability factor.

Los métodos de evaluación de la uniformidad de riego estiman las condiciones hidráulicas de funcionamiento del sistema de riego y su influencia en la aplicación de láminas de agua, con base en las necesidades hídricas de un cultivo. El modelo de evaluación utilizado en la presente investigación fue el polinomial. El ensayo evaluó el funcionamiento del sistema de riego con 4 presiones de operación distintas, medidas a la salida de la válvula del módulo de riego, y por cada presión de operación se tomaron 16 datos de caudales, en 5 módulos de riego instalado con el aspersor autocompensado Nelson R10. Como resultado se obtuvo el coeficiente de uniformidad, el coeficiente de distribución, el área adecuadamente irrigada y el factor de adecuación del riego. Uno de los principales resultados fue la no existencia de diferencia significativa entre las presiones mientras esta se mantengan en el rango de autocompensación, por otro lado, en el coeficiente de distribución sí existen diferencias significativas entre los tratamientos, a pesar de que todos dan valores mayores al 90%, en contraste con los porcentajes del área relativa adecuadamente regada, que no superan el 50% en ninguno de los tratamientos. Con lo anterior se pudo validar y verificar que el aspersor Nelson R10 autocompensado, una vez instalado en campo, cumple con las características técnicas de operación expuestas en el catálogo del fabricante, sin embargo, sí se debe manejar y controlar la lámina de riego aplicada.
