Abstract: Research Object: lettuce 'AFICION', fertilized with different organic products. Research Methods: pH, electrochemical quality evaluation methods, biocrystalisation. Evaluation of energetic value P. electrochemical research methods (pH, rH, conductivity λ, product energy value P calculation, biocrystallization research method, picture evaluation. Results. In the research area holistic methods are used in determines food quality indicators. Electrochemical indicators (redox potential, pH, a specific conductivity) were used there to calculate energy value P. The research was carried out Investigations were carried out in 2018 in greenhouses of JSC Žiežmarių Gėlės. The temperature in the greenhouse was maintained at 25-29 °C, and 80% relative humidity. Plant observations were made regularly every week. There were 6 variants in the experiment where 5 different organic products were used for lettuce fertilization: 1. Control; 2. Biohumic acids; 3. Raskila; 4. Biohumus; 5. Bioorg; 6. Humic life. Biohumus, Biohumic acids and Raskila fertilized lettuce yielded a statistically unreliable mass. Bioorg and Humic life fertilized lettuce mass was statistically lower during the marketing time. All organic products used for lettuce fertilization statistically significantly reduced an amount of nitrate. The greatest positive effect of organic fertilizers on grown lettuce was found in salads, which were fertilized with Biohumus (216.93) Biohumicacids (214.10 g) and Raskila (212.00 g). Compared to the control variant (201.33 g), Bioorg (171.80 g) and Humolife (172.33 g) produced statistically less weight (R05 = 17.014). The maximum nitrate content of different organic fertilizers, when applied different types of organic products, were accumulated in the control variant (1525 mg kg-1). Compared to the control variant, all other lettuces, fertilized with organic fertilizers, have accumulated significantly lower
