The Effects of Precipitation on Corn Yields

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

Experiment Process 1. 2. 3. 4. 5. 6. 7. 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

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

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