Adicionar Tag | Resumo: | 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 |
