| dc.description | Agriculture is a productive activity that has been expanding primarily through the production of foods such as cereals, which are the most widely cultivated. Rice is an example of this, as it is the staple food for society. Worldwide, it ranks second only to wheat in terms of harvested area. This research aims to determine the agronomic and productive performance of the promising L-37 rice line grown in the Guare area, Los Ríos province. The methodology used was a nonparametric design with Kruskal Wallis analysis, including comparisons of means. The research was conducted on a farm owned by Mr. Frank Franklin Fajardo López, located in the Guare area. Three replicates (three samples with areas of 4 m² taken from one hectare of crop) and two cultivars (L-37 and SFL-11) will be considered for the analysis. With a total population of 348 seedlings for both the promising line L-37 and SFL-011 in R1, R2, and R3, the plot evaluation technique consisted of direct counting of individuals, tillers, panicles, grains, plant-to-row spacing, and yield estimation. Two treatments, L-37 and SFL-11, were used in three replicates. Regarding results, the promising rice line L-37 showed fewer panicles, reaching 20.27 panicles, compared to the commercial variety SFL-11 (22.37), which maintains a much higher number of panicles. L-37 had a lower percentage of vain numbers (8.79), compared to the commercial variety SFL-11 (12.73). It is found that the promising rice line L-37 has a distance of 31.93 cm from the commercial variety, which is slightly larger at 33.13 cm. It turns out that the shorter the distance, the greater the number of plants. Although there are similarities in the agronomic characteristics of the commercial variety SFL-11 and the promising line L-37, the latter is the one that truly shines in terms of yield and generates an impressive range of 6.5 to 7 tons per year. It is concluded that the promising line L-37 has a high significance with the control in yield and is a promising line for the benefit of farmers in the area. | es_ES |

| dc.description.abstract | La agricultura es una actividad productiva que se ha ido extendiendo y principalmente al producir alimentos como los cereales del cual suelen ser los más cultivados, un ejemplo de ellos se tiene el cultivo de arroz ya que es el alimento básico para la sociedad. A nivel mundial, ocupa el segundo lugar después del trigo con respecto a superficie cosechada. La presente investigación tuvo como objetivo determinar el comportamiento agronómico y productivo de la línea promisoria de arroz L-37 cultivada en la zona de Guare, provincia de Los Ríos. La metodología utilizada fue un diseño experimental de bloques completamente al azar, aplicando la prueba de Tukey incluyendo las comparaciones de medias. La investigación se desarrolló en una finca de propiedad del Sr. Frank Franklin Fajardo López, ubicada en la zona de Guare. Para el análisis se considerarán tres repeticiones (tres muestreos con áreas de 4 m² tomadas en una hectárea de cultivo) y dos cultivares (L-37 y SFL-11). Con una población total tanto para la Línea promisoria L-37 y la SFL-011 en R1, R2, R3, es de 348 plántulas, La técnica utilizada para la evaluación de parcelas fueron las del conteo directo de los individuos, macollos, panículas, granos, el distanciamiento entre planta e hilera y estimación del rendimiento, se utilizaron dos tratamientos, L-37 y SFL-11 en tres repeticiones. En cuanto a resultados, la línea promisoria de arroz L-37 mostro un menor de panículas, que alcanzo un valor de 20,27 panículas en comparación de la variedad comercial SFL-11(22,37) que mantiene un numero de panículas mucho mejor. La L-37 presento un menor porcentaje de números vanos (8,79), antes la variedad comercial SFL-11 (12,73). Se encuentra que la línea promisoria de arroz L-37 tiene una distancia de 31,93 cm antes la variedad comercial que es ligeramente mayor a 33,13 cm que resulta, que cuanto menor sea la distancia, mayor es el numero de plantas. Aunque hay similitudes en las características agronómicas de la variedad comercial SFL-11 y en la línea promisoria L-37, esta ultima es la que realmente resalta en términos de rendimiento y crea un rango impresionante de 6,5 a 7 toneladas por año. Donde se concluye que la línea promisoria L-37 tiene una alta significancia con el testigo en el rendimiento y es una línea promisoria para el beneficio de los agricultores de la zona | es_ES |
