What do yield maps do from year to year for the same crop?

1. Remain constant

2. Vary

3. Improve

4. Decline

The correct answer is: Vary

Yield maps from the same crop can vary from year to year due to several factors that influence crop performance, such as changes in weather conditions, soil health, pest pressures, and agricultural practices. Each growing season may bring different amounts of rainfall, temperature fluctuations, or even unforeseen events like droughts or floods that can significantly impact yields. Additionally, farmers might change their management practices or try different inputs, which can lead to variable outcomes. This variability is critical for farmers as it helps them understand how different variables affect their yields over time. By analyzing yield maps, farmers can pinpoint areas within their fields that perform consistently well or poorly, allowing them to make more informed decisions for future planting and management strategies. It also enables them to adjust their practices based on the information gathered from previous years, fostering adaptability and resilience in their operations.
