The research focused on agronomical, physiological, qualitative, and mineral characteristics of lettuce.<\/p><h3 data-start=\"697\" data-end=\"743\">Impact of Biostimulants on Lettuce Yield<\/h3><p data-start=\"745\" data-end=\"1260\">Lettuce plants grown under sub-optimal N conditions (0N kg ha\u22121) exhibited a notable increase in fresh yield when treated with TG41 alone (45%) and even greater improvement with TG41 combined with VBP <a href=\"https:\/\/www.hello-nature.com\/int\/scientific-publications\/\">biostimulants<\/a> (67%). Interestingly, under both optimal (70N kg ha\u22121) and supra-optimal (140N kg ha\u22121) N levels, these biostimulants still enhanced growth, demonstrating their broad effectiveness. These results suggest that <strong data-start=\"1169\" data-end=\"1212\">biostimulants boost lettuce performance<\/strong>, particularly in nutrient-limited conditions.<\/p><h3 data-start=\"1262\" data-end=\"1313\">Physiological and Photosynthetic Enhancements<\/h3><p data-start=\"1315\" data-end=\"1582\">At 48 days after transplanting, both TG41 alone and TG41+VBP treatments significantly increased CO\u2082 assimilation compared to untreated controls. Consequently, the plants displayed improved photosynthetic efficiency, which contributed to higher biomass accumulation.<\/p><h3 data-start=\"1584\" data-end=\"1642\">Improved Mineral Composition and Nutritional Quality<\/h3><p data-start=\"1644\" data-end=\"2082\">The application of TG41+VBP <a href=\"https:\/\/www.hello-nature.com\/int\/scientific-publications\/\">biostimulants<\/a> increased leaf potassium (K) by 10% and magnesium (Mg) by 12% relative to untreated plants. Moreover, nitrate content was significantly lower in all treated lettuce, supporting safer consumption. Importantly, in non-fertilized conditions, biostimulant-treated plants produced premium-quality lettuce, with enhanced antioxidant activity, total ascorbic acid (+61%\u201391%), and total phenols (+14%).<\/p><h3 data-start=\"2084\" data-end=\"2133\">Conclusion: Sustainable Lettuce Cultivation<\/h3><p data-start=\"2135\" data-end=\"2496\">Overall, the findings confirm that <strong data-start=\"2170\" data-end=\"2259\">biostimulants boost lettuce growth, mineral nutrition, and health-promoting compounds<\/strong>, offering a sustainable strategy for improving crop yield and quality even under low N conditions. These results provide strong evidence for integrating TG41 and vegetal biopolymer biostimulants into modern lettuce production systems.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4193794 elementor-widget elementor-widget-text-editor\" data-id=\"4193794\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Publication: Agronomy<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f10b506 elementor-widget elementor-widget-text-editor\" data-id=\"f10b506\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;ekit_we_effect_on&quot;:&quot;none&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default elementor-inline-editing pen\" data-elementor-setting-key=\"title\" data-pen-placeholder=\"Type Here...\">Y.
