Abstract
La hidroponía en invernadero representa una alternativa clave y sostenible dentro de la agricultura orgánica, ya que contribuye significativamente a la conservación del agua y fomenta la producción de hortalizas saludables. En este contexto, la Técnica de Película Nutritiva (NFT) se destaca como un sistema hidropónico diseñado para optimizar el consumo de agua y nutrientes, consolidándose como una herramienta valiosa para la agricultura sostenible y la obtención de alimentos saludables. El suministro de nutrientes en los sistemas hidropónicos NFT busca simplificar la gestión para que los agricultores mantengan las cantidades de nutrientes ajustadas a las necesidades de las plantas, promoviendo un uso racional de los recursos. Aunque los sistemas de Técnica de Película Nutritiva (NFT) varían en tamaño, complejidad y composición, estos ofrecen una excelente vía para cultivar de manera sostenible y ecológica. Para validar esto, en un estudio se utilizaron 12 tubos de PVC, asignando tres tubos a cada nivel de espesor de la película de solución nutritiva. Se trasplantaron 7 almácigos en cada tubo, resultando en un total de 84 plántulas en el módulo hidropónico. Se observó que los cultivos cosechados en el módulo hidropónico piramidal, bajo condiciones de invernadero, exhibieron características físicas superiores, incluyendo altura, peso del fruto y desarrollo radicular, específicamente en el grupo P4. Los análisis foliares confirmaron una tendencia positiva en los niveles de macro y micronutrientes en las pruebas P3 y P4, lo que indica que el espesor ideal de la lámina de solución nutritiva se ubica entre los rangos evaluados en dichas pruebas. En consecuencia, la hidroponía en invernadero representa un método de producción eficiente que conserva el agua, prescinde del suelo y elimina el uso de plaguicidas.
Greenhouse hydroponics represents a key and sustainable alternative within organic agriculture, as it contributes significantly to water conservation and promotes the production of healthy vegetables. In this context, the Nutrient Film Technique (NFT) stands out as a hydroponic system designed to optimize water and nutrient consumption, consolidating itself as a valuable tool for sustainable agriculture and healthy food production. Nutrient supply in NFT hydroponic systems seeks to simplify management for farmers to keep nutrient amounts adjusted to plant needs, promoting a rational use of resources. Although Nutrient Film Technique (NFT) systems vary in size, complexity and composition, they offer an excellent avenue to grow crops in a sustainable and environmentally friendly manner. To validate this, a study used 12 PVC tubes, assigning three tubes to each level of nutrient solution film thickness. Seven seedlings were transplanted into each tube, resulting in a total of 84 seedlings in the hydroponic module. It was observed that crops harvested in the pyramidal hydroponic module, under greenhouse conditions, exhibited superior physical characteristics, including height, fruit weight and root development, specifically in the P4 group. Foliar analysis confirmed a positive trend in macro and micronutrient levels in the P3 and P4 trials, indicating that the ideal thickness of the nutrient solution sheet is between the ranges evaluated in these trials. Consequently, greenhouse hydroponics represents an efficient production method that conserves water, dispenses with soil and eliminates the use of pesticides.
