Resumen
Este estudio se lo realizó en la época seca del 2015, en el recinto Piñal Arriba, cantón Daule, provincia del Guayas. Objetivos: a) evaluar el comportamiento de las características agronómicas del cultivo de arroz ante la aplicación de diferentes dosis de los bioestimulantes: Cytokin, Forti-gro, Seaweed extract, Bio-solar y Bio-energía; b) elaborar un análisis económico comparativo entre los mejores tratamientos y el testigo comercial. Se utilizaron cinco bioestimulantes cuyas combinaciones de tratamientos fueron seis. Se utilizó el diseño bloques completamente al azar, con cinco repeticiones y seis tratamientos mediante la prueba de Duncan al 5 % de probabilidad. Se concluyó: a) Que la aplicación de los bieostimulantes Seaweed extract, Bio-solar y Bio–energía presentaron los mayores promedios de altura de planta, número de macollos y número de panículas, mientras que el Cytokin tuvo mayor longitud de panícula y granos por panícula. b) El mayor rendimiento de los granos de arroz se obtuvo con las aplicaciones de Seaweed extract efectuadas a los 20 y 40 días después del trasplante. c) La mejor tasa de retorno marginal (433 %) se obtuvo con las aplicaciones de Seaweed extract, realizadas a los 20 y 40 días.
This study was made in the dry season of 2015, on the premises Piñal Up, Daule canton, Guayas province. Objectives: a) evaluate the performance of agronomic traits of rice to the application of different doses of bioestimulantes: Cytokin, Forti-gro, Seaweed extract, Bio-solar and bio-energy; b) develop a comparative economic analysis among the best treatments and the commercial control. Bioestimulantes five combinations were used which had six treatments. The randomized complete block design, with five replications and six treatments by Duncan test at 5% probability was used. It was concluded that: a) the application of bieostimulantes Seaweed extract, Bio-solar and bio-energy had the highest average plant height, number of tillers and number of panicles, while the Cytokin had longer panicle and grains panicle. b) The highest yield of the rice grains was obtained with Seaweed extract applications made at 20 and 40 days after transplantation. c) The best marginal return rate (433%) was obtained with the application of Seaweed extract, taken at 20 and 40 days.
