Abstract

Lettuce grown under recycled hydroponics ensures efficient water and nutrient utilization. However, lettuce yield is often reported to be declined from successive cultures for accumulating phytotoxic root exudates. Degrading toxic exudates by titanium-based electrode and increasing photosynthetic efficiency by adding green light would improve lettuce yield. Alternate current electro-degradation (AC-ED) was applied along with addition of green light in light spectrum to enhance lettuce yield. Lettuce seedlings were grown in plant factory using half-strength of Enshi solution. Three consecutive cultures were performed under three combinations of LEDs [Red (R):Green (G): Blue (B) viz. 235:00:59, 211:30:53 and 187:60:47 μmol m-2 s-1] using renewed (RW), non-renewed (NR) and AC-ED applied non-renewed (NR+AC-ED) nutrient solutions. Results showed that in subsequent cultures, lettuce yield declined in NR solution under 187:60:47 of R:G:B. Contrarily, NR+AC-ED solutions showed maximum lettuce growth and enhanced about 30% of yield under 30 μmol m-2 s-1 of green light addition. However, addition of 60 μmol m-2 s-1 of green light showed lower yield under all nutrient solutions. Nutritional quality of lettuce was not varied by nutrient solutions and LEDs. Our study recommends applying AC-ED for reutilizing fertigation water and addition of 30 μmol m-² s-1 green light for higher lettuce yield under successive cultivation.
