Resumen
La investigación se realizó durante la época seca de 2015 en la finca San Eloy, en el Recinto “Los Jazmines”, Parroquia El Laurel, Cantón Daule, Provincia del Guayas. Tuvo como objetivos específicos: a) Determinar la mejor dosis del fertilizante Green Edge en el comportamiento agronómico del cultivo de arroz, b) Evaluar el comportamiento agronómico del cultivo de arroz, c) Realizar un análisis económico de los tratamientos para medir factibilidad de su uso.
Los factores estudiados fueron aplicaciones de el fertilizante Green Edge, a base de NPK (15-15-15) + 10% ácidos húmicos-fulvicos y 2.5% de algas marinas, a los 6 días después del trasplante al inicio del cultivo y fueron distribuidas en las siguientes concentraciones: 0, 25, 50 y 75kg/ha.
Se utilizó un diseño experimental de bloques completamente al azar (DBCA), con cuatro tratamientos distribuidos aleatoriamente en seis repeticiones. Cada parcela tenía un tamaño de 15m², en la comparación de las medias se utilizó la prueba de Tukey al 5% de probabilidad.
Se concluyó: La mejor dosis se obtuvo en el tratamiento cuatro con 75 kg de Green Edge/ha siendo el rendimiento de 8546 kg/ha de arroz paddy, ajustado al 14% de humedad.
En las variables altura de planta y peso de 1000 semillas no fueron significativa estadísticamente, pero a diferencia de números de macollo y longitud de panícula mostraron significancia entre repeticiones y el rendimiento fue significativo entre tratamientos. Pero mostrando una alta significancias fue la variable granos por panícula entre repeticiones.
26
La mejor Tasa Marginal de retorno se lo consiguió con el tratamiento dos,
25 kg/ha de Green Edge, seguido del tratamiento cuatro con 75 kg/ha de
Green Edge.
El tratamiento cuatro resultó no dominado.
Por lo tanto se recomienda en el Cantón Daule la aplicación del fertilizante
The research was conducted during the dry season of 2015 in the San Eloy, in the Campus "Los Jazmines" Parroquia El Laurel, Daule canton, Guayas Province. He had specific objectives: a) To determine the best dose of fertilizer Green Edge in the agronomic performance of rice, b) To evaluate the agronomic performance of rice cultivation, c) Perform an economic analysis of treatments to measure feasibility of their use. The factors studied were applications of fertilizer Green Edge, based NPK (15-15-15) + 10% humic-fulvic acid and 2.5% of seaweed, at 6 days after transplantation at the beginning of the crop and were distributed at the following concentrations: 0, 25, 50 and 75kg / ha. An experimental design of randomized complete block design (RCBD) with four treatments randomly distributed in six replications. Each plot had a size of 15m², in the comparison of means test was used Tukey at 5% probability. It concluded: The best dose was obtained in the treatment four with 75 kg of Green Edge / ha yield being 8546 kg / ha of paddy rice, adjusted to 14% moisture. In the variables plant height and 1000 seed weight they were not statistically significant, but unlike numbers of tillering and panicle length showed significance between repetitions and yield was significant between treatments. But it was showing a high significances grains per panicle variable between repetitions. 28 The best rate of return Marginal got treatment two 25 kg / ha of Green Edge, followed by treatment with four 75 kg / ha of Green Edge. Four treatment was not dominated. Therefore the application of the soil fertilizer Green Edge is recommended
