In the early 1800’s, wheat production was done on average by four men and two oxen. These producers made about 200 bushels.
After the US Civil War, better tillage equipment was used. Also, the westward expansion and the introduction of railroads led to better access and better trading.
By the late 1800’s, sowing with drills increased productivity, cradled replaces sickles, sickles were then replaced by reapers and binders, and steam powered threshing machines and steam roller mills were introduced. By this time, six people and 36 horses produced 20,000 wheat bushels.
Corn production improved between 1850 and 1890 due to hybrid cropping techniques to produce hybrid corn varieties through cross breeding. These varieties are genetically engineered to withstand harsh weather and respond better to soil fertilizer.
