Abstract: The yield gap—the difference between potential and actual yield—represents a fundamental challenge in agriculture. Closing this gap is crucial for increasing the productivity of arable land, thereby ensuring sustainable food security without expanding the agricultural footprint. This study explores the concept of the yield gap and its critical role in boosting crop production per unit area, a strategy essential for meeting the global food demand in the face of a growing population.
