  1. The Effects of Precipitation on Corn Yields

  2. Hypothesis • Corn Yields are affected by the amount of precipitation. • Variable Factors may have an affect on corn yields. • Insufficient precipitation may lead to lower corn yields.

  3. Experiment Process • Form hypothesis • Decide contributing factors • Plot location of experiment • Observe plot and corn crop in plot • Research data from previous years in each field • Research average precipitation in Bates Co. for each of those years • Make conclusion based on data

  4. Factors Controlled Variable Precipitation Intervals of Precipitation Temperatures Planting Dates Harvesting Dates insects • Seed Variety • Fertilizer • Soil Type

  5. Corn Field • North Field: T39N-R29W-S30-SE1/8 (80 Acres) • Zumbrunnen Field: T39N-R30W-S34-NE1/4 of the SE1/4 (40 Acres) • Sum of All Fields: T39: R29, R30

  6. Corn Yields

  7. Good and Bad Good Corn Cob Bad Corn Cob

  8. Precipitation

  9. Corn Yields and Total Precipitation

  10. Conclusions Derived from Data • Corn Yields are affected by the amount of precipitation. • Insufficient precipitation does lead to lower corn yields. • Variable factors do have affect on corn yields. • Additional Conclusion: Excess precipitation also leads to lower corn yields.

  11. Works Cited • National Agricultural Statistics Service http://www.nass.usda.gov/Statistics by State/Missouri/Publications/Weather/Data/ • http://www.asgrowanddekalb.com/products/corn/Pages/drought.aspx

  12. Seed Variety • Proved to produce higher yields during drought than Pioneer OptimumAQUAmax corn hybrids

  13. Fertilizer Potash- form of potassium Phosphate- form of phosphorus Anhydrous Ammonia- form of nitrate
