Although biostimulants have attracted attention for sustainable agricultural systems, their efficacy remains poorly understood.

The gap

Consensus across the literature

Supporting evidence — 3 representative gaps

• Enhancing organic fruit production: insights into biostimulant applications for sustainable growth, quality, and resilience in diverse agroecological settings (2025) · doi

  However, further research on specific crops, varieties, and optimal application periods is emphasized to maximize biostimulant benefits in diverse agroecological conditions.

• Potato ( <i>Solanum tuberosum</i> L.) Response to Amino Acids Biostimulants Treatment under Organic Farming System (2026) · doi

  Therefore, further research is warranted to achieve a more comprehensive understanding of their efficacy and to optimize their application under diverse agricultural conditions. Despite the increasing interest in biostimulants and the expanding body of knowledge on their use, their variable efficacy remains incompletely understood in many cases.
