Comportamiento agronómico y productivo de la línea promisoria de arroz (Oryza sp.) L-17 cultivada en la zona de Pimocha, Provincia Los Ríos

Rice (Oryza sativa L.) is the main food of inhabitants in developing countries and is the second most consumed cereal in the world. Its global demand increases due to population growth and consumption models in different regions. Rice is one of the most important crops for Ecuador, generating a significant contribution to the economy, in addition to contributing to and guaranteeing the food security of the population and generating thousands of direct and indirect jobs throughout the production chain. The progress of the sector in productivity issues during the last decades has been slow. This project aims to determine the agronomic and productive behavior of the promising L-17 rice line cultivated in the Pimocha area, province of Los Ríos. In this research, a methodology was carried out, with a non-parametric statistical design with the use of Tukey analysis including comparisons of means. For the analysis, three repetitions will be considered (three samplings with areas of 4 m² taken in one hectare of crop) and two cultivars (L-17 and SFL-11). The technique used to evaluate the plots was direct counting of individuals, tillers, panicles, grains, the distance between plant and row and estimation of yield, two treatments were used. Regarding the results, the promising line L-17 showed a greater number of panicles, which reached a value of 21.68, compared to the SFL-11 variety, which obtained a lower number of panicles 19.27. Line L-17 had a higher percentage (6.04%) of wasted grain, compared to the commercial line, SFL-11, which had a lower amount of wasted grain (5.5%). It is found that the promising line L-17 has a distance of 36 cm from the commercial SFL 11 of 34.6 cm, which results in the smaller the distance, the greater the number of plants. Although there are similarities in the agronomic characteristics of the SFL-11 line and the promising L-37 line, it is the latter that really shines in terms of performance and creates an impressive range of 6.5 to 7 tons per year. In conclusion, the promising line L-17 is distinguished from the commercial line SFL 11 by having a high significance of difference, both in character, yield and production cost, which makes it a promising line for farmers.

El arroz (Oryza sativa L.), es el principal alimento de los habitantes en los países en desarrollo y es el segundo cereal de mayor consumo en el mundo, su demanda global aumenta por el crecimiento de la población y por los modelos de consumo de diferentes regiones, El arroz es uno de los cultivos más importantes para Ecuador, generando un aporte significativo a la economía, además de contribuir y garantizar la seguridad alimentaria de la población y generar miles de empleos directos e indirectos a lo largo de la cadena productiva. El avance del sector en temas de productividad durante las últimas décadas ha sido lento este proyecto tiene como objetivo Determinar el comportamiento agronómico y productivo de la línea promisoria de arroz L-17 cultivada en la zona de Pimocha, provincia de Los Ríos. En esta investigación se realizó una metodología, con un diseño estadístico no paramétrico con el uso de análisis de tukey incluyendo las comparaciones de medias. Para el análisis se considerarán tres repeticiones (tres muestreos con áreas de 4 m² tomadas en una hectárea de cultivo) y dos cultivares (L-17 y SFL-11). La técnica utilizada para la evaluación de las parcelas fueron la del conteo directo de los individuos, macollos, panículas, granos, el distanciamiento entre planta e hilera y estimación del rendimiento se utilizaron dos tratamientos. En cuanto a los resultados, la línea promisoria L-17 mostró un mayor número de panículas, que alcanzó un valor de 21.68, en comparación con la variedad SFL-11, que obtuvo un menor número de panículas 19.27. La línea L-17 tuvo un porcentaje más alto (6,04%) de grano vano, ante la línea comercial, SFL-11 que tuvo menor cantidad de grano vano (5,5%). Se encuentra que la línea promisoria L-17 tiene una distancia de 36 cm de antes la comercial SFL 11 de 34,6 cm, que resulta, cuanto menor sea la distancia, mayor será el número de plantas. Aunque hay similitudes en las características agronómicas de la línea SFL-11 y en la línea promisora L-37, esta es la última que realmente brilla en términos de rendimiento y crea un rango impresionante de 6.5 a 7 toneladas por año. En conclusión, la línea promisoria L-17 se distingue de la línea comercial SFL 11 por tener una alta significancia de diferencia, tanto en caracteres, como en rendimiento y en el costo de producción, lo que la hace una línea prometedora para los agricultores.
