Aplicación de silicio en tres densidades de siembra sobre el rendimiento del cultivo de arroz (Oryza sativa) bajo riego en el sector San Agustín de Chilintomo- Guayas

The present experimental work was carried out at km. 14,5 of the Babahoyo-Mata de Cacao road: “San Agustín” Campus; with geographic coordinates of 79º 26´ of West Longitude and 1º56´ of South latitude, and with a height of 20 m.s.n.m . The rice variety INDIA SFL -11 was used as planting material. An analysis was used; bifactorial type, considering silicon dose (FACTOR B) and planting spacing (FACTOR A). The Randomized Complete Blocks experimental design was used with five treatments and 4 repetitions, the significance test used was Tukey's 95% probability. All necessary agricultural work was carried out in rice cultivation for its normal development, such as soil preparation, planting, irrigation, fertilization, weed control, phytosanitary control and harvesting. To estimate the effects of the treatments, the following data were taken: plant height, number of tillers, number of panicles, length of panicles, grains per panicles, weight of 1000 grains, yield, economic analysis. Based on the results obtained, it was determined that in the variable panicle length, the T1 treatment with a density of 20X20 and a dose of 1,0 l / ha showed highly significant differences with respect to the treatment without application. Treatment T2 with a density of 20X25 and a dose of 1,0 l / ha reacted more than the other treatments. Regarding yield, the T3 treatment with a density of 20X30 and a dose of 0,5 l / ha, with 8,6 tons obtained a significant difference with respect to the rest of the treatments. In the economic analysis it was found that the best economic performance was obtained with the T2 treatment with a density of 20X25 and a dose of 0,5 l / ha with $ 645,45

El presente trabajo experimental se realizó en el km. 14,5 de la vía Babahoyo-Mata de Cacao: Recinto “San Agustín”; con coordenadas geográficas de 79º 26´ de Longitud Oeste y 1º56´de latitud sur, y con una altura de 20 m.s.n.m. Como material de siembra se utilizaron la variedad de arroz INDIA SFL -11. Se utilizo un análisis; de tipo bifactorial, considerando dosis de silicio (FACTOR B) y distanciamiento de siembra (FACTOR A). Se empleó el diseño experimental Bloques Completos al Azar con cinco tratamientos y 4 repeticiones, la prueba de significancia utilizada fue de Tukey al 95 % de probabilidad. Se realizaron todas las labores agrícolas necesarias en el cultivo de arroz para su normal desarrollo como preparación de suelo, siembra, riego, fertilización, control de malezas, control fitosanitario y cosecha. Para estimar los efectos de los tratamientos, se tomaron los siguientes datos: altura de planta, número de macollos, número de panículas, longitud de las panículas, granos por panículas, peso de 1000 granos, rendimiento, análisis económico. Por los resultados obtenidos se determinó que en la variable longitud de panícula, el tratamiento T1 con una densidad de 20X20 y una dosis de 1,0 l/ha mostro diferencias altamente significativas con respecto al tratamiento sin aplicación. El tratamiento T2 con una densidad de 20X25 y una dosis de 1,0 l/ha reacciono de manera superior con respecto a los tratamientos restantes. Referente a rendimiento el tratamiento T3 con una densidad de 20X30 y una dosis de 0,5 l/ha, con 8,6 toneladas obtuvo una diferencia significativa con respecto al resto de los tratamientos. En el análisis económico se pudo constatar que el mejor rendimiento económico lo obtuvimos con el tratamiento T2 con una densidad de 20X25 y una dosis de 0,5 l/ha con $645,45.
