Evaluación de la relación Carbono/Nitrógeno de tres tipos de sustratos bajo un sistema semi-hidropónico al aire libre en el cultivo de frutilla (Fragaria ananassa) variedad albión con agua magnetizada al 100%

The investigation was carried out in the city of Ibarra, province of Imbabura. The main objective of the research was to evaluate the Carbon / Nitrogen ratio of three types of substrates under a semi-hydroponic system in the open air in the cultivation of strawberry (Fragaria ananassa) variety albion with 100% magnetized water. In order to partially reduce the loss of nitrogen in the soil and maximize the content of macronutrients in the substrates, the variations of macronutrients such as nitrogen, phosphorus, potassium, calcium and magnesium of various organic materials such as sheep manure and husks were compared. coffee, rice husk, pomina and black soil, among the different substrates produced. The experimental design of divided plots was applied, with three treatments and three repetitions, using a total of 360 albion variety strawberry seedlings with 11 days of vegetative growth, established in 24 experimental units, with 15 seedlings in each. The substrate factor was\; T1: Application of black earth + pomina + coffee husk, T2: Application of black earth + pomina + sheep manure, T3: Application of black earth + pomina + rice husk, T4: (control) with application of pomina + earth black. The water factor as\; A1: water without magnetic induction and A2: water with magnetic induction. The variables under study were: number of days to flowering, plant height, number of fruits, yield, number of days to harvest, brix degrees. A good effect was evidenced in the implementation of magnetism in water. All 100% magnetic induction treatments captured the best results. These results favored the increase in yield with a reduction of 21 days in the flowering stage and by the end of the days at harvest, with respect to the control.

La investigación se realizó en la ciudad de Ibarra, provincia de Imbabura. El objetivo principal de la investigación fue evaluar la relación Carbono/ Nitrógeno de tres tipos de sustratos bajo un sistema semi-hidropónico al aire libre en el cultivo de frutilla (Fragaria ananassa) variedad albión con agua magnetizada al 100%. Para reducir parcialmente la pérdida de nitrógeno en el suelo y maximizar el contenido de macronutrientes en los sustratos, se compararon las variaciones de los macronutrientes como el nitrógeno, fósforo, potasio, calcio y magnesio de diversas materias orgánicas como el estiércol de ovino y cascarilla de café, cascarilla de arroz, pomina y tierra negra, entre los diferentes sustratos elaborados. Se aplicó el diseño experimental de parcelas divididas, con tres tratamientos y tres repeticiones, utilizando un total de 360 plántulas de frutilla variedad albión de 11 días de crecimiento vegetativo, establecidas en 24 unidades experimentales, con 15 plántulas en cada una. El factor sustrato fue; T1: Aplicación de tierra negra + pomina + cascarilla de café, T2: Aplicación de tierra negra + pomina + estiércol de ovino, T3: Aplicación de tierra negra + pomina + cascarilla de arroz, T4: (testigo) con aplicación de pomina + tierra negra. El factor agua como; A1: agua sin inducción magnética y A2: agua con inducción magnética. Las variables en estudio fueron: número de días a la floración, altura de la planta, número de frutos, rendimiento, número de días a la cosecha, grados brix. Se evidenció un buen efecto en la implementación de magnetismo en agua. Todos los tratamientos al 100 % de inducción magnética obtuvieron los mejores resultados. Dichos resultados favorecieron el incremento del rendimiento con una reducción de 21 días en la etapa de floración y por ende días a la cosecha, con respecto al testigo.
