Resumen
El ensayo se realizó en la parroquia Banife, cantón Daule, provincia
del Guayas en la propiedad urbana del Sr. Jorge Alberto Tutiven Veliz. Los
objetivos fueron: a) Caracterizar agronómicamente los siete cultivares de
frijol nacional e introducido en condiciones urbanas; b) Determinar los
materiales que tengan adaptación al ecosistema del rubro de producción en
estudio; c) Estimar la relación costo/beneficio de los cultivares estudiados.
Se realizó la investigación con siete variedades de frijoles
introducidos y nacionales, Se utilizó el diseño de bloques completamente al
azar con cuatro repeticiones, la comparación de medias se la realizo,
mediante la prueba de Tukey al 5% de probabilidades .Se analizaron ocho
variables fisiológicas.
Las conclusiones fueron: 1) Las condiciones climáticas del cantón
Daule provincia del Guayas, si tienen influencia en cada uno de los
resultados experimentales tomados a las variables: altura de planta (cm),
días de floración, días de maduración, número de vainas/planta, número de
granos/vaina, longitud de la vaina (cm) peso de semillas por 100 gramos y
rendimiento en kg/ha de cada una de las variedades de frijol; 2) Las
variedades de frijol tumbe, paciencia, borloto, seda y haba presentaron una
mejor adaptación a la zona donde se realizó el experimento; 3) Al efectuar
la cuantificación general del ensayo el tratamiento tres fue el que mejor
resultado brindó, porque obtuvo un beneficio bruto de 2451,18 USD. En el
caso de los beneficios netos el tratamiento seis alcanzó el mayor valor con
USD 2159,18.
The present study was carried out in the Banife parish, Daule canton, Guayas province in a lot owned by Mr. Jorge Alberto Tutiven Veliz. The objectives were: a) To characterize agronomically the seven bean cultivars and introduce them; B) To determine the materials that have adaptation to the ecosystem under study to initiate the formation of a germplasm bank; C) Quantify the costs of the experimental test. Research was conducted with seven been varieties introduced and national. A complete randomized block design with four replications was applied, the comparing means was conducted through the Tukey test with 5% probability. Eight physiological variables were analyzed. The conclusions were: 1) The weather conditions of Daule canton in Guayas province, present influence in each of the experimental results taken to the variables: plant height (cm), flowering days, maturation days, Plant, number of grains / pod, pod length (cm) weight of 100 seeds and yield in kg/ha of each of the bean varieties; 2) Bean varieties such as tumbe, paciencia, borloto, seda and haba showed a better adaptation in the area where the experiment was carried out; 3) At the time of the Cost quantification of treatment three was the one with the best net profit with USD 2451,18. In terms of net benefits, the treatment six reached the highest value with USD 2159,18.
