Abstract

The vegetable production sector is currently fronting several issues mainly connected tothe increasing demand of high quality food produced in accordance with sustainable horticulturaltechnologies. The application of biostimulants, particularly protein hydrolysates (PHs), might befavorable to optimize water and mineral uptake and plant utilization and to increase both productionperformance and quality feature of vegetable crops. The present study was carried out on celery plantsgrown in a tunnel to appraise the influence of two PHs, a plant-derived PH (P-PH), obtained from soyextract and an animal PH (A-PH), derived from hydrolyzed animal epithelium (waste from bovinetanneries) on yield, yield components (head height, root collar diameter, and number of stalks),mineral composition, nutritional and functional features, as well as the economic profitability of PHsapplications. Fresh weight in A-PH and P-PH treated plants was 8.3% and 38.2% higher, respectivelythan in untreated control plants. However, no significant difference was found between A-PH treatedplants and control plants in terms of fresh weight. Head height significantly increased by 5.5% and16.3% in A-PH and P-PH treated plants, respectively compared with untreated control (p ≤ 0.05).N content was inferior in PHs treated plants than in untreated control. Conversely, K and Mg contentwas higher in A-PH and P-PH treated plants as compared to the untreated ones. Furthermore,A-PH and P-PH improved ascorbic acid content by 8.2% and 8.7%, respectively compared with thenon-treated control (p ≤ 0.001). Our results confirmed, also, that PHs application is an eco-friendlytechnique to improve total phenolic content in celery plants. In support of this, our findings revealedthat animal or plants PH applications increased total phenolics by 36.9% and 20.8%, respectivelycompared with untreated plants (p ≤ 0.001).
