Maximum economic yield in crop production is defined as the point at which the extra value generated from the grain produced equals the costs incurred from the additional inputs used, such as fertilizers. This concept directly links the economic aspects of crop yield to agronomic practices. By optimizing the amount of fertilizer applied, producers can achieve a level of yield where the revenue generated from selling the additional crops balances out the expenses associated with purchasing and applying those fertilizers.

In other words, pursuing maximum economic yield ensures that farmers are not only focused on producing the highest volume of crop but are also considering the financial implications of their inputs and practices. This approach allows for sustainable farming by promoting efficiency and cost-effectiveness, ultimately enhancing profitability.

The other options do not accurately represent maximum economic yield. For instance, simply achieving maximum crop yield through any nutrient application neglects the balance between input costs and output value. Focusing solely on the maximum amount of fertilizer without regard to economic return can lead to unnecessary spending and environmental concerns. Additionally, yield determined solely by weather conditions ignores the role of management decisions and input strategies that can significantly affect crop productivity.
