The need to increase agricultural production to feed a steadily growing population may clash with the more environmentally friendly but less efficient production methods required. Therefore, it is important to try to reduce the use of chemical inputs without compromising production. In this scenario, natural biostimulants have become one of the most sought-after and researched technologies. In the present study, the results of a greenhouse experiment on hydroponic tomatoes ( L.) are presented, which involved comparing the use of ordinary NPK fertilizer (Cerbero) with the use of NPK fertilizers enriched with 0.5% protein hydrolysate of plant origin (Cerbero Green) at both standard (100%) and reduced (70%) fertilization rates. The results highlight how the use of Cerbero Green fertilizers improves the production performance of tomatoes. More specifically, they show that the use of Cerbero Green leads to higher marketable yields, especially under reducing fertilizer use, ensuring a positive net change in profit for the grower. In addition, carbon footprint analysis has revealed that the use of Cerbero Green reduces the environmental impact of hydroponic tomato growing practices by up to 8%. The observed higher yield of hydroponically grown tomatoes even with reduced fertilization rates underlines once again the key role of natural biostimulants in increasing both the economic and environmental sustainability of horticultural production.
为养活不断增长的人口而增加农业产量的需求，可能与所需的更环保但效率较低的生产方法相冲突。因此，在不影响产量的情况下尽量减少化学投入物的使用非常重要。在这种情况下，天然生物刺激剂已成为最受追捧和研究最多的技术之一。在本研究中，展示了一项关于水培番茄（L.）的温室实验结果，该实验涉及在标准（100%）和降低（70%）施肥率下，比较普通氮磷钾肥料（Cerbero）与添加0.5%植物源蛋白水解物的氮磷钾肥料（Cerbero Green）的使用情况。结果突出了使用Cerbero Green肥料如何提高番茄的生产性能。更具体地说，结果表明使用Cerbero Green能带来更高的可销售产量，特别是在减少肥料使用的情况下，确保种植者的利润有正向净变化。此外，碳足迹分析表明，使用Cerbero Green可将水培番茄种植方式对环境的影响降低多达8%。即使在施肥率降低的情况下，水培番茄仍有较高产量，这再次凸显了天然生物刺激剂在提高园艺生产的经济和环境可持续性方面的关键作用。
