In modern agriculture, the reduction of environmental impact, ensuring both high and stable yield and high quality, is a primary goal. To avoid an excessive use of external inputs, without compromising crop performance, the increase of soil nutrient availability and nutrient use efficiency is fundamental in a sustainable potato production. In this framework, the use of plant biostimulants, such as humic substances, seaweed and microalgal extracts, hydrolysed proteins and amino acids and microorganisms, could give a great help to farmers. Due to the agronomic importance and the keen interest in these substances, the aim of this review was to survey and summarise the outputs derived from scientific published studies on the combination of potato and plant biostimulants. In the literature, several in vitro, growth chamber, glasshouse and field experiments were reported. Field experiments were conducted in different environmental conditions, using different genotypes, and all the applied plant biostimulants showed beneficial effects on both productive and qualitative potato parameters. Seaweed extract and humic substances could also reduce the normal dose of fertiliser without reducing yield. Among quality features, tuber size, contents of protein, vitamin C, starch and phenols are the principal parameters influenced by plant biostimulants. Weaknesses related to the use of plant biostimulants were shown and were related to different effectiveness of products due to their origin, production process and microbial species. In addition, product/strain-genotype interactions have been shown. Environmental factor, agricultural practice and timing of treatment can influence the effectiveness of both microbial and non-microbial plant biostimulants.

在现代农业中，减少对环境的影响，确保高产稳产，是首要目标。为了避免过度使用外部投入物，同时又不影响作物性能，提高土壤养分可用性和养分利用效率是马铃薯可持续生产的基础。在此框架下，使用植物生物刺激素，如腐殖质、海藻和微藻提取物、水解蛋白质和氨基酸以及微生物，可以为农民提供很大帮助。由于对这些物质的农艺重要性和浓厚的兴趣，本次审查的目的是调查和总结有关马铃薯和植物生物刺激素组合的科学已发表研究的成果。在文献中，有几种体外、生长室、温室和田间试验都有报道。在不同的环境条件下，使用不同的基因型进行田间试验，所有应用的植物生物刺激素都对马铃薯的产量和质量参数显示出有益的影响。海藻提取物和腐殖质也可以在不降低产量的情况下减少肥料的正常用量。在质量特征中，块茎大小、蛋白质含量、维生素 C、淀粉和酚类是受植物生物刺激素影响的主要参数。显示了与使用植物生物刺激素相关的弱点，这些弱点与产品的不同功效有关，因为它们的来源、生产过程和微生物种类。此外，还显示了产品/菌株-基因型相互作用。环境因素，
