Plant-derived protein hydrolysates (PHs) act as biostimulants, stimulating physiological responses in leaves and roots that enhance nutrient uptake and assimilation.<\/p><h3 data-start=\"575\" data-end=\"650\">Foliar Application of Protein Hydrolysates Boosts Spinach Performance<\/h3><p data-start=\"651\" data-end=\"1027\">In this study, greenhouse baby spinach (Spinacia oleracea L.) received foliar applications of a legume-derived PH at 0 or 4 mL L\u22121 under four nitrogen (N) levels (0, 15, 30, or 45 kg ha\u22121). The biostimulant effects on spinach growth were evident: at low N levels (0 and 15 kg ha\u22121), PH-treated plants produced 33.3% and 24.9% more fresh yield compared to untreated controls.<\/p><h3 data-start=\"1029\" data-end=\"1100\">Nutritional and Physiological Responses to Biostimulant Treatment<\/h3><p data-start=\"1101\" data-end=\"1685\">PHs contain amino acids and small peptides that function as signaling molecules, triggering auxin- and gibberellin-like activities. These <a href=\"https:\/\/www.hello-nature.com\/int\/scientific-publications\/\">biostimulant<\/a> effects on spinach growth increase nutrient accumulation (P, Ca, Mg), enhance photosynthetic efficiency, and improve the SPAD index. Moreover, total amino acid content rose significantly at 0, 15, and 30 kg ha\u22121 N, highlighting the biostimulant\u2019s role in metabolic enhancement. Interestingly, polyphenol content decreased with PH application, suggesting a trade-off between growth stimulation and secondary metabolite accumulation.<\/p><h3 data-start=\"1687\" data-end=\"1733\">Sustainable Benefits of Biostimulant Use<\/h3><p data-start=\"1734\" data-end=\"2054\">Overall, biostimulant effects on spinach growth provide a sustainable strategy to boost yield, improve nitrogen use efficiency, and mitigate soil fertility limitations under low-input conditions. Foliar PH applications represent a practical approach for optimizing spinach performance in nutrient-limited environments.<\/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...\">P.
