🌽🌱 Yield Contest Calculator
NYC&SGA Official Contest Formulas
🌽 Corn Yield Calculator
Step 1: Calculate Row Width
Formula: Row width (inches) ÷ 12 = Row width (feet)
Example: 30 inches ÷ 12 = 2.5 feet
Example: 30 inches ÷ 12 = 2.5 feet
Step 2: Calculate Acres Harvested
Formula: Total row length × row width ÷ 43,560 = acres harvested
Example: 24,200 × 2.5 ÷ 43,560 = 1.39 acres
Example: 24,200 × 2.5 ÷ 43,560 = 1.39 acres
Step 3: Calculate Bushels (15.5% moisture)
Formula: Total pounds × (100 - % moisture) × 0.01 ÷ 47.32 = bushels
Example: 16,580 × (100 - 21.25) × 0.01 ÷ 47.32 = 275.92 bushels
Example: 16,580 × (100 - 21.25) × 0.01 ÷ 47.32 = 275.92 bushels
Step 4: Calculate Yield per Acre
Formula: Bushels harvested ÷ acres harvested = bushels per acre
Example: 275.92 ÷ 1.39 = 198.50 bushels per acre
Example: 275.92 ÷ 1.39 = 198.50 bushels per acre
Second Harvest (Required if first harvest > 350 bu/acre)
Formula: (Harvest A + Harvest B) ÷ 2 = Final Yield
🌱 Soybean Yield Calculator
Step 1: Calculate Acres Harvested
Formula: Length × width ÷ 43,560 = acres harvested
Example: 180 × 585 = 105,300 sq. ft. ÷ 43,560 = 2.42 acres
Example: 180 × 585 = 105,300 sq. ft. ÷ 43,560 = 2.42 acres
Step 2: Calculate Yield per Acre
Formula: Total pounds × (100 - % moisture) × 0.01 ÷ 52.2 ÷ acres harvested = yield per acre
Note: 52.2 = dry weight of 1 bushel of soybean at 13% moisture
Example: 7,200 × (100 - 15.5) × 0.01 ÷ 52.2 ÷ 2.42 = 48.15 bushels per acre
Note: 52.2 = dry weight of 1 bushel of soybean at 13% moisture
Example: 7,200 × (100 - 15.5) × 0.01 ÷ 52.2 ÷ 2.42 = 48.15 bushels per acre
