Biostimulants like Nurspray\u00ae, based on hydroxycinnamic acid oligomers, offer a promising solution. This study evaluated the impact of different application timings of Nurspray\u00ae on tomato yield and fruit quality under open-field conditions. Four treatments were tested: T1 (control), T2 (Nurspray\u00ae at BBCH 19\u201351), T3 (Nurspray\u00ae at BBCH 19\u201351\u201361), and T4 (Nurspray\u00ae at BBCH 19\u201323\u201351). The results showed significant improvements in root development, canopy cover, and flowering for T3 and T4, with root systems increasing by up to 103% in T4 compared to the control. Fruit yield and quality were enhanced, with a reduction in blossom-end rot (BER) incidence to 0% in T3 and T4, compared to 5% in the control. Additionally, T4 produced the highest dry matter content in fruits. The optimal application strategy was three doses of Nurspray\u00ae at BBCH 19\u201323\u201351, enhancing both yield and fruit quality. This study highlights the potential of Nurspray\u00ae as an organic biostimulant in sustainable tomato farming.<\/jats:p>","DOI":"10.3390\/agronomy14102317","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T06:30:03Z","timestamp":1728455403000},"page":"2317","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hydroxycinnamic Acid Oligomers-Based Biostimulant Nurspray\u00ae Enhances Tomato Yield, Fruit Quality, and Reduces Blossom-End Rot"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7852-0706","authenticated-orcid":false,"given":"Lien","family":"Gonz\u00e1lez-P\u00e9rez","sequence":"first","affiliation":[{"name":"General Directorate of Research and Community Engagement, Universidad de Las Am\u00e9ricas, Quito 170503, Ecuador"}]},{"given":"Eduardo","family":"Tejera","sequence":"additional","affiliation":[{"name":"Bio-Chemoinformatics Group, Faculty of Engineering and Applied Sciences, Universidad de Las Am\u00e9ricas, Quito 170503, Ecuador"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,9]]},"reference":[{"key":"ref_1","unstructured":"Wakil, W., Brust, G.E., and Perring, T.
