Estimating Crop Yield Per Acre
Plant density = plantable area / (row spacing x plant spacing). One acre = 6,272,640 sq inches.
Common spacings: corn 30-36 in rows, soybeans 15-30 in, wheat 6-8 in, vegetables 12-48 in.
Actual yields vary with soil, rain, fertilization. Reduce estimates 10-20% for realistic field conditions.
Frequently Asked Questions
Good corn yield?
US average about 175 bushels (9,800 lbs) per acre. Top producers achieve 250+.
How spacing affects yield?
Closer = more plants but less per plant due to competition. Each crop has an optimal density.
Convert to bushels?
Corn=56 lbs/bushel, wheat/soybeans=60 lbs. Divide total pounds by bushel weight.
What reduces yield?
Drought, pests, disease, poor soil, frost, weeds. Realistic yields are 70-90% of theoretical max.
