Effect
Increased nitrogen N use efficiency
Decreased nitrogen N use efficiency
No effect on nitrogen N use efficiency
Nutricin treated lettuce, cv. 'Hawking', outdoor grown in a DFT (Deep Flow technique) system with reduced nitrogen occasionally showed significant differences in comparison to untreated control grown in the same conditions: at some assessments/stress situations vigour was lower, chlorophyll red and the NDRE higher (more chlorophyll) and the WDVI higher (more biomass). Analysis of the harvested crop showed - depending on the stress situation - significantly higher concentrations nitrogen and boron but lower concentrations zinc and copper.
