Relaciones magnesio y nitrógeno en soluciones nutritivas y el rendimiento de pepino en sistema hidropónico cerrado

Abstract: Soluciones nutritivas con balance en las relaciones, proporciones y concentraciones de los iones optimizan la ef iciencia en el uso de nutrimentos y el rendimiento de los cultivos. El objetivo de este trabajo fue evaluar, en invernadero, tres relaciones porcentuales Mg2+/cationes (20, 40 y 60/100) y tres de NO3-/aniones (40, 60 y 80/100) y su combinación sobre la composición mineral, la ef iciencia de uso de nutrimentos (EUN) y el rendimiento de pepino (Cucumis sativus cv. Poinsett 76) desarrollado en hidropon… Show more

“…The reduction in RWC and leaf area can be also ascribed to the higher value of electrical conductivity (EC) of the nutrient solution supply as reported by different authors related to salinity conditions [22] and the consequent restriction of water uptake [23]. Similarly, Parra-Terraza et al [24] noted that there was an increase in the osmotic potential under increasing nutrient concentration in the nutrient solution resulting in an impairment of water uptake.…”
