Agronomic Performance and Phytochemical Profile of Lettuce Grown in Anaerobic Dairy Digestate

Anaerobic liquid dairy digestate is a by-product of waste anaerobic digestion from operations and associated with environmental risks if not handled properly, particularly nutrient leaching losses, water contaminations, greenhouse gas emissions. We tested the applications anerobic (AD) as biofertilizer source in vegetable production to integrate food industry management for sustainable environments. used deep culture system assess effects AD effluent alone, inorganic solution (NS), combination NS on growth, yield, phytonutrient profile heavy metal contamination assessment hydroponically produced lettuce. Lettuce had lower leaf area, total chlorophyll content, fresh biomass; however, it displayed significantly higher chicoric acid (200%), chlorogenic (67%), luteolin (800%), quercetin-3-O-β-d-glucuronide (378%), quercetin-3-glucoside quercetin-3-O-(6″-O-malonyl)-β-D-glucoside (1077%), folate (248%), pantothenic phenolics (111%), antioxidants (44%), soluble sugars (253%) compared control (inorganic feed). The AD-produced lettuce also showed bioaccumulation human consumption. Based various results, we may conclude that utilization hydroponics can offer harvest better phytonutrients, benefits.
