Resumen
La presente investigación se la realizó entre la época lluviosa y seca del
2016, en el terreno de propiedad del Sr. Manuel León Burgos, ubicado en el
recinto Independencia km 49 vía Daule - Santa Lucia, cantón Daule,
provincia del Guayas.
El objetivo general planteado. Evaluar macerados orgánicos en el cultivo de
arroz (Oryza sativa L.) para eliminar la Hydrellia sp.Los Objetivos
específicos: 1) Determinar los macerados orgánicos más eficientes para el
control de Hydrellia sp, en el cultivo de arroz. 2) Determinar el porcentaje (%)
de control de plagas con la aplicación de macerados orgánicos. 3) Realizar
un análisis económico de los tratamientos, este experimento tuvo una
duración de cuatro meses incluyendo la evaluación de datos esto fué desde
el mes de abril 2016 – julio del 2016.
Se utilizó la variedad de arroz INIAP-11; se probaron tres tipos de macerados
orgánicos con la misma dosificación, el diseño del experimento fue en
bloques completamente al azar, en cuatro tratamientos incluido el testigo y
seis repeticiones, que combinados dieron un total de 24 tratamientos. Se
evaluaron algunas variables agronómicas con análisis estadístico para
determinar el macerado que brindo las mejores condiciones de rendimiento,
calidad y rentabilidad.
Las conclusiones que se tuvieron al final del presente trabajo de
investigación fueron: Los macerados orgánicos más eficientes para el control
de Hydrellia sp. Fueronneem más ají. El porcentaje de control de Hydrellia
sp. Con maceradosorgánicosfué de 97% en el ciclo del cultivo del arroz.
Según el análisis estadístico realizado a los tratamientos, el mejor
rendimiento y peso de mil granos se obtuvieron donde se aplicaron los
macerados de neem más ají. En el cantón Daule los factores climáticos y de
suelo son propicios para extender el uso de productos orgánicos en general,
demostrándose en el presente estudio la efectividad de los macerados
orgánicos para el control de Hydrellia sp.
The present investigation was carried out between the dry and rainy season of 2016, in the property owned by Mr. Manuel León Burgos, located in the Independencia km 49 grounds via Daule - Santa Lucia, Daule canton, Guayas province. The overall objective. Evaluating organic macerates in rice cultivation (Oryza sativa L.) to eliminate Hydrellia sp. Specific Objectives: 1) To determine the most efficient organic macerates for the control of Hydrellia sp in rice cultivation. 2) To determine the percentage (%) of pest control with the application of organic macerates. 3) To carry out an economic analysis of the treatments, this experiment lasted approximately four months including the evaluation of data, which was from April 2016 - July 2016. The INIAP-11 rice variety was used; Three types of organic macerates were tested with the same dosage, the design of the experiment was completely randomized blocks, in four treatments including the control and six replicates, which combined gave a total of 24 treatments. Some agronomic variables were evaluated with statistical analysis to determine the maceration that provided the best conditions of yield, quality and profitability. The findings at the end of the present were: The most efficient organic macerates for the control of Hydrellia sp were neem plus chili. The percentage of control of Hydrellia sp with organic macerates was 97% in the cycle of rice cultivation. According to the statistical analysis performed on the treatments, the best yield and weight of one thousand grains were obtained where the macerates of neem plus pepper were applied. In Daule, weather and soil factors are favorable to extend the use of organic products in general, demonstrating in the present study the effectiveness of organic macerates for the control of Hydrellia sp. From the analysis of the present study we can obtain an alternative of use of organic products for the control of pests and diseases of the rice crops.
