Resumen
La presente investigación se la realizó desde Octubre del 2014 a Enero del 2015 en el
sitio “Las Maravillas” de, cantón Rocafuerte, localizada geográficamente a 01°02’08’’ de
Latitud Sur, y a 80° 27’02” de Longitud Oeste, con una altitud de 20 msnm según datos
de la Estación Meteorológica de Portoviejo, la cual tuvo como objetivo generar una
alternativa nutricional en el cultivo de acelga variedad White Ribbed para mejorar la
productividad y rentabilidad. Donde los tratamientos utilizados fueron abonos orgánicos
(Fossil Shell Agro, Ecoflora y Biol) en dosis baja (20 g/litro), media (30 g/litro) y alta (40
ml/litro) y se utilizó el diseño estadístico de Bloques Completos al Azar (DBCA en
Arreglo Bifactorial (3x3+1) con tres repeticiones, registrando un total 30 unidades
experimentales.
Donde lo resultados, en la variable altura de planta el factorial vs el testigo a los 75 días
el testigo del agricultor (Urea + Abono Completo) produjo la mayor altura con 66,93 cm
en relación al factorial que presentó el menor valor con 59,60 cm de altura. En el diámetro
de hoja a los 75 días el factor abonos con Fossil Shell Agro reportó el mayor valor con
24,45 cm de diámetro de hoja y en las interacciones este abono y la dosis baja de 20 g/litro
registró el mayor valor con 25,70 cm de diámetro de hoja. En tanto que en las
comparaciones el testigo del agricultor fue superior con 23,77 cm de diámetro de hoja.
En tanto que el número de hojas por planta estuvo precedido a los 75 días por el testigo
del agricultor (Urea + Abono orgánico) con 20,67 hojas por planta y en el número de
hojas cosechadas, reportó 30,26 hojas cosechadas en relación al factorial que presentó el
menor valor con 29,20 hojas cosechadas. Por su parte el peso de la planta el factorial
registró el mayor peso con 0,79 kg por planta en relación al testigo del agricultor (Urea +
Abono completo) que presentó el menor valor con 0,74 kg.
Según el análisis de presupuesto parcial, se determinó que la mejor alternativa económica
se consiguió el abono orgánico Ecoflora con la dosis alta 40 g/litro, el cual registró un
Beneficio Neto de USD 1530,00 con un Costo Variable de USD 105,00 que se manifestó
en una Tasa de Retorno Marginal de 239,78%.
The present investigation was carried out it from October from the 2014 to January of the 2015 in the place "The Marvels" of, canton Rocafuerte, located geographically at 01°02'08 '' of South Latitude, and at 80° 27'02" of Longitude West, with an altitude of 20 msnm according to data of the Meteorological Station of Portoviejo, which had as objective to generate a nutritional alternative in the cultivation of beet variety White Ribbed to improve the productivity and profitability. Where the used treatments were organic payments (Fossil Shell Agriculture, Ecoflora and Biol) in low dose (20 g/litro), he/she mediates (30 g/litro) and high (40 ml/litro) and the statistical design of Complete Blocks was used at random (DBCA in Arrangement Bifactorial (3x3+1) with three repetitions, registering a total 30 experimental units. Where that been, in the variable plant height the factorial vs the witness to the 75 days the farmer's witness (Urea + I Pay Complete) it produced the biggest height with 66,93 cm in relation to the factorial one that presented the smallest value with 59,60 cm of height. In the leaf diameter to the 75 days the factor payments with Fossil Shell Agriculture reported the biggest value with 24,45 cm of leaf diameter and in the interactions this payment and the low dose of 20 g/litro registered the biggest value with 25,70 cm of leaf diameter. As long as in the comparisons the farmer's witness was superior with 23,77 cm of leaf diameter. As long as the number of leaves for plant was preceded to the 75 days by the farmer's witness (Urea + I Pay organic) with 20,67 leaves for plant and in the number of harvested leaves, it reported 30,26 leaves harvested in relation to the factorial one that presented the smallest value with 29,20 harvested leaves. On the other hand the weight of the plant the factorial one registered the biggest weight with 0,79 kg for plant in relation to the farmer's witness (Urea + I Pay complete) that presented the smallest value with 0,74 kg. According to the budget analysis partially, it was determined that the best economic alternative was gotten the organic payment Ecoflora with the dose high 40 g/litro, which registered a Net profit of USD 1530,00 with a Variable Cost of USD 105,00 that he/she showed in a Rate of Marginal Return of 239,78%.
