Evaluación de diferentes densidades de siembra con el método al voleo, de la línea promisoria L- 17 de arroz (Oryza sp) en la localidad de Babahoyo”

Rice is the staple food for half of the world's population and the second most produced cereal globally, surpassed only by maize and wheat. In Ecuador, it is an essential food, with an average consumption of 50 kg per person per year. The provinces of Guayas and Los Ríos lead its production, with an annual yield of approximately 778,680 metric tons of milled rice. However, declines in yield cause significant economic losses for farmers.This study aimed to evaluate the agronomic and productive performance of the promising rice line L-17 compared to the commercial variety SFL-11 on the fields of Agronomist Wellington Rodríguez in the canton of Babahoyo, Los Ríos province. The research was conducted using six treatments, each with three replications, at different planting densities for both the L-17 line and the commercial SFL-11 variety.A completely randomized block design (DBCA) was used with subdivided plots of 25 m² (5m x 5m). Statistical analysis was carried out using the InfoStat 2020 software (ANOVA), and the Tukey test was applied to evaluate key variables such as plant height, number of tillers, panicles, grain width and length (with and without husk), vigor, population, and the number of plants per square meter. The SFL-11 cultivar showed the highest number of tillers, with a measurement of 618.06, surpassing the L-17 cultivar, which recorded a lower value of 552.83 in comparison with the other line. Treatment 3 of the L-17 line achieved the highest profitability percentage, with 24.28%, while in the control (SFL-11), Treatment 5 obtained a profitability of 15.27%

El arroz es la base alimenticia de la mitad de la población mundial y el segundo cereal más producido a nivel global, superado solo por el maíz y el trigo. En Ecuador, es un alimento esencial, con un consumo promedio de 50 kg por persona al año. Las provincias de Guayas y Los Ríos lideran su producción, con un rendimiento anual de aproximadamente 778.680 toneladas métricas de arroz pilado. Sin embargo, las bajas en el rendimiento ocasionan significativas pérdidas económicas para los agricultores. Este estudio tuvo como objetivo evaluar el comportamiento agronómico y productivo de la línea promisoria de arroz L-17 en comparación con la variedad comercial SFL-11 en los predios del Ing. Agr. Wellington Rodríguez en el cantón de Babahoyo provincia de Los Ríos. La investigación se llevó a cabo mediante 6 tratamientos cada uno con tres repeticiones con diferentes densidades tanto la línea L-17 como la variedad comercial Sfl-11. Se utilizó un diseño de bloques completamente alzar (DBCA) con parcelas subdivididas 25 m2 (5mx5m). El análisis estadístico fue llevado acabó con el software de InfoStat 2020 (ANOVA), también se utilizó el Test de Tukey evaluando variables clave como altura de planta, número de macollos, panículas, ancho y largo de grano con cáscara y sin cáscara, vigor, población, número de plantas por m2. El cultivar SFL-11 presento el mayor número de macollos con una medida de 618,06 superando al cultivar de la L-17 con una medida menor de 552,83 en comparación con la otra línea. El Tratamiento 3 de la línea L -17 obtuvo un mayor porcentaje de rentabilidad con un 24,28 % y en el testigo (SFL -11) fue el tratamiento 5 con 15,27% de rentabilidad.
