Resumen
Esta investigación se llevó a cabo desde 28/07/2016 hasta el 27/11/2016 en el cantón Pedro
Carbo, provincia del Guayas con el objetivo de investigar la “EVALUACIÓN DE DOS
HÍBRIDOS DE MAIZ (Zea mayz L.) BAJO DOS FORMAS DE APLICACIÓN DE
FERTILIZANTE NITROGENADO Y COMPLETO”. Generar alternativas
tecnológicas en nutrición de maíz, para mejorar la productividad y rentabilidad del cultivo
de maíz, Evaluar agronómicamente dos híbridos de maíz con dos formas de aplicación de
fertilizantes con base de N y NPK.
Se utilizaron dos híbridos de maíz: AGRI-104 y trueno NB7443. Los niveles de completo
empleados fueron de: 180, 40 y 60 kg/ha, también se incluyó un tratamiento de 180 kg
N/ha. Se utilizó el diseño de bloques al azar, con arreglo factorial (2x2x2+2), con tres
repeticiones. Se evaluaron variables agronómicas, de concentración nutrimental (N, P y K).
Dentro de los resultados se determinó el mejor comportamiento agronómico entre los dos
híbridos ya anunciados, el que dio mejor respuesta agronómica entre los dos híbridos fue el
AGRI-104, y los testigos de cada tratamiento.
En la evaluación agronómica tenemos que
El hibrido que demostró mejor resultado fue la Agri104 porque presento mayor
tolerancia a la sequía. Es más tolerante al ataque de plagas.
Los híbridos mantiene una producción estable con condiciones adecuadas.
Necesita una cantidad moderada de fertilizante como N P K.
En el análisis económico el promedio general de la variable fue de 10,36 y el
coeficiente de variación de 4,55%.
This research was carried out from 07/28/2016 to 11/27/2016 in the canton Pedro Carbo, province of Guayas, with the objective of investigating the "EVALUATION OF TWO MAIZE HIBRIDES (Zea mayz L.) UNDER TWO FORMS APPLICATION OF NITROGEN FERTILIZER AND COMPLETE ". To generate technological alternatives in maize nutrition, to improve the productivity and profitability of the maize crop. To evaluate agronomically two hybrids of maize with two forms of application of fertilizers with base of N and NPK. Two maize hybrids were used: AGRI-104 and thunder NB7443. The levels of complete employees were: 180, 40 and 60 kg / ha, also included a treatment of 180 kg N / ha. We used the randomized block design, with factorial arrangement (2x2x2+2), with three replicates. Agronomic variables of nutrient concentration (N, P and K) were evaluated. Among the results, the best agronomic behavior between the two hybrids was determined, which gave the best agronomic response between the two hybrids was the AGRI-104, and the controls for each treatment. In the agronomic evaluation we have to • The hybrid that showed the best result was Agri104 because it showed greater tolerance to drought. It is more tolerant to pest attack. • Hybrids maintain stable production with adequate conditions. • You need a moderate amount of fertilizer such as N P K. • In the economic analysis the overall average of the variable was 10.36 and the coefficient of variation of 4.55%.
