Comportamiento agronómico y productivo de la línea promisoria de arroz (Oryza sp.) L-38 en la zona de Baba, provincia Los Ríos

Rice, Oryza sativa L., is one of the most important crops worldwide. It is the most consumed cereal after wheat. The objectives were to determine the agronomic and productive performance of the promising rice line (Oryza sp.) L-38 in the Baba area, Los Ríos province. Stakes were used to measure random points, samples of 2 x 2 m (4 m2), in 3 replications for each line/cultivar. A completely randomized block experimental design was performed, with the Tukey test at 95% probability. The results indicate that the promising line L-38 has a higher number of plants per m2 of 52.00 plants, planting distance between rows with 26.67 cm, number of tillers per plant with 38.77 cm, height of plants per m2 of 96.63 cm, panicles per plant with 36.37 panicles, number of grains per panicle with 139.21 grains, length of grain with hull with 9.85 cm, number of empty grains with 4.22 grains, width of grain without hull with 1.91 mm, higher yield with 8652.83 kg / ha and the control variety SFL-11 has a higher planting distance between plants with 26.63 cm, panicle length with 23.79 cm and length of grain without hull with 7.01 mm. The conclusions determined that the promising L-38 line stands out for its adaptability in the Baba region. Its good results in agronomic characteristics are reflected in its excellent grain quality compared to the SFL-11 variety. This makes it a promising and economically beneficial option for rice farmers. L-38 outperforms the control rice variety and is considered a more productive alternative for producers in the Baba region of Los Ríos Province, Ecuador.

El arroz Oryza sativa L., es uno de los cultivos con mayor importancia a nivel mundial, es el cereal que más se consume en el mundo después del trigo. Los objetivos planteados fueron determinar el comportamiento agronómico y productivo de la línea promisoria de arroz (Oryza sp.) L-38 en la zona de Baba, provincia Los Ríos. Se utilizó estacas para medir puntos al azar, las muestras de 2 x 2 m (4m2), en 3 repeticiones por cada línea/cultivar. Se realizó un diseño experimental de Bloques completamente al azar, con la prueba de Tukey al 95% de probabilidad. Los resultados indican que la línea promisoria L-38 tiene mayor número de plantas por m2 de 52,00 plantas, distanciamiento de siembra entre hileras con 26,67 cm, número de macollos por plantas con 38,77 cm, altura de plantas por m2 de 96,63 cm, panículas por planta con 36,37 panículas, número de granos por panícula con 139,21 granos, longitud de grano con cáscara con 9,85 cm, número de granos vanos con 4,22 granos, ancho de grano sin cáscara con 1,91 mm, mayor rendimiento con 8652,83 kg/ha y la variedad testigo SFL-11 tiene mayor distanciamiento de siembra entre plantas con 26,63 cm, longitud de panículas con 23,79 cm y longitud de grano sin cáscara con 7,01 mm. Las conclusiones determinaron que las línea promisoria L-38 se destaca por su adaptabilidad en la zona de Baba, viendo reflejado sus buenos resultados en las características agronómicas por su buena calidad de grano en referencia a la variedad SFL-11, lo que lo posiciona como una opción prometedora y beneficiosa económicamente para los agricultores arroceros y L-38 supera a la variedad testigo de arroz, considerándose como una alternativa más productiva para los productores de la zona de Baba, provincia de Los Ríos, Ecuador.
