Crop Yield Analysis: Performance Across Varieties, Locations, and Time
This report explores crop yield patterns across different varieties, agricultural sites, and time periods. It highlights how specific crop types perform under varying conditions and identifies locations with consistently higher productivity, offering insights into factors influencing agricultural output.
This section examines how crop varieties perform over time and identifies the most productive agricultural sites, providing a foundational understanding of yield dynamics.
The Average Yield for every crop Variety declined from the Year 1931 to 1932, suggesting a universally less productive growing season in the latter year. Despite this widespread drop in production, the relative performance hierarchy was largely preserved across both years. For instance, Wisconsin No. 38 consistently outperformed all other varieties, while Svansota consistently showed the lowest yield.
The Waseca Site stands out with a substantially higher Average Yield compared to all other locations. Following the leader, Crookston and Morris form a distinct second tier of performance with closely grouped yields. The remaining sites show a gradual decline in productivity, with Grand Rapids recording the lowest average yield in this comparison.
A comparison between harvest dates reveals a general decline in crop Yield from 1931 to 1932 across most combinations of Site and Variety. The Waseca and Crookston sites were top performers in 1931, with the Trebi variety also showing high yields across multiple locations. While overall output was lower in 1932, the yield reduction was particularly pronounced for the Glabron and No. 475 varieties at the Grand Rapids site, suggesting a strong negative interaction between location and specific crop types in that year's conditions.
Crop yield analysis reveals consistent performance hierarchies among varieties and distinct productivity levels across agricultural sites. The observed decline in overall yield from 1931 to 1932, coupled with specific variety-site interactions, underscores the influence of environmental factors on agricultural output. These insights can inform decisions regarding crop selection and resource allocation to optimize future yields.
