Comparing Yields Across Systems

American reports speak bushels per acre, European ones tons per hectare, Turkish agronomy kg per decare — and a bushel is a volume whose weight depends on the crop: wheat and soybeans 60 lb, corn 56, barley 48. The converter applies the correct test weight for the selected crop: 60 bu/ac of wheat = 4.03 t/ha, while 60 bu/ac of barley is only 3.23 t/ha.

Sanity anchors: world average wheat sits near 3.5 t/ha, top European farms exceed 9; US corn averages ~175 bu/ac (11 t/ha). If a converted figure looks off by 10×, a decare/hectare mix-up is the usual suspect.

Frequently Asked Questions

Why does the crop matter for bushels?

A bushel is 35.24 liters of volume; grains differ in density. USDA standard test weights (lb/bu): wheat 60, soybeans 60, corn 56, rye 56, barley 48, oats 32.

What is kg/da?

Kilograms per decare (1,000 m²) — standard in Türkiye. Multiply by 10 for kg/ha, divide by 100 for t/da. 500 kg/da wheat equals 5 t/ha.
