Productividad de la línea promisoria de arroz L-07 (Oryza sp) comparada con la variedad comercial SFL-11 en la zona de CEDEGE, Montalvo, provincia de Los Ríos

Rice (Oryza sativa L.) represents an important item in the basic family basket worldwide, with global and consumer demand. In Montalvo, rice cultivation is essential for farmers in that area according to studies. The L-07 rice variety is relevant for its high productivity and its resistance and tolerance to pests and diseases. This research was conducted at the field/laboratory level, with inferential descriptive statistics, with the objective of improving the productivity of the promising rice line L-07 (Oryza sp) compared to the commercial variety SFL-11 in the CEDEGE area, Montalvo, Los Ríos province, with three replications in the two varieties. The following variables were evaluated: plant height (cm), number of tillers per plant, number of panicles per plant, panicle length (cm), total number of grains per panicle, length (mm) and width (mm) of grains with and without hull; and yield (kg/ha). A nonparametric Kruskal-Wallis analysis design was performed. The results obtained in this research indicate that the promising rice line L-07 (Oryza sp) is more productive than the commercial variety SFL-11, showing higher yields per hectare and better adaptation to the agroclimatic conditions of the CEDEGE area in Montalvo, in agreement with Rodríguez (2024). Over the past few decades, the rice sector has experienced significant technological transformation, which has led to significant global improvements in the relationship between the various production chains. This work shows that the promising rice line L-07 has good plant height for mechanization and early maturity for efficient crop rotation, and is more resistant to pests. Its adaptability and productivity make it a promising option under diverse agricultural conditions and at different planting times. While there are similarities in the agronomic characteristics of the SFL-11 variety and the promising line L-07, it is clear that the line with the greatest stability is the L-07.

El arroz (Oryza sativa L.), representa un rubro importante en la canasta básica familiar a nivel mundial, con demanda global y de consumo. En Montalvo, el cultivo de arroz es fundamental para los agricultores de esa zona según los estudios. La variedad de arroz L-07 es relevante por su alta siendo productivo y que tenga resistencia y sea tolerante a plagas y enfermedades. Esta investigación fue realizada a nivel de campo/laboratorio, con estadística descriptiva inferencial, con el objetivo de mejorar la Productividad de la línea promisoria de arroz L-07 (Oryza sp) comparando con la variedad comercial SFL-11 en la zona de CEDEGE, Montalvo, provincia de Los Ríos, con tres repeticiones en las dos variedades. Se evaluaron las variables: Altura de planta (cm), número de macollos por planta, número de panículas por planta, longitud de panículas (cm), número de granos totales por panícula, longitud (mm) y ancho (mm) de granos con y sin cáscara; y rendimiento (kg/ha). Se realizo un diseño no paramétrico de análisis de Kruskal Wallis. Los resultados obtenidos en esta investigación indican que la línea promisoria de arroz L-07 (Oryza sp) supera en la productividad a la variedad comercial SFL-11, mostrando mayor rendimiento por hectárea y mejor adaptación a las condiciones agroclimáticas de la zona de CEDEGE, Montalvo, concuerda con Rodríguez (2024). Durante estas últimas décadas, el sector arrocero ha experimentado una gran importancia a transformación tecnológica, que ha significado de importantes niveles global de un mejoramiento sustancial en la relación entre la diferente cadena productiva. Este trabajo La línea promisoria de arroz L-07 tiene una buena altura de planta para una buena mecanización, y madurez temprana para rotación eficiente de cultivos y es más resistente a plagas. Su adaptabilidad y productividad la hacen una opción prometedora en diversas condiciones agrícolas, y en diferente tiempo de siembra. Si bien existen similitudes en las características agronómicas de la variedad SFL-11 y la línea promisoria L-07 dando a conocer que la línea que tiene mejor estabilidad es la L-07.
