A Look at Minnesota Corn Yields over Time

Dale R. Hicks, Agronomy and Plant Genetics
Corn yields in Minnesota have been excellent for the past few years and have exceeded the expectations based on weather and growing conditions during the growing seasons. Whole field yields during the past three years have exceeded 200 bushels per acre for many growers in the central to southern regions of the state. As a result, we may begin to wonder if these high yields are now normal and should we expect them in the future or have they been blips on the yield profile? It may not be very accurate to use the past to predict the future, but it is one method to look forward to corn yields of the next few years. That's the objective of this paper.

Wet conditions lead to harvest delays

Lizabeth Stahl, Extension Educator-Crops
Soggy fields and submerged crops can be found in areas throughout the state due to recent rainfall events. What effect will these late-season wet conditions and even flooding have on corn and soybeans as we wait for field conditions to improve and harvest to resume?

Corn grain drying rates

Dale R. Hicks, Agronomy and Plant Genetics
Drying costs will be higher this fall because LPGas prices have and are rising quickly during the past few weeks. Corn growers may want to delay harvest to allow for more field drying which could reduce drying costs. How much field drying can be expected?

Field drying is an evaporative process of moisture moving out of kernels through the husks. High temperature and low humidity are the primary factors, which drive the rate of field drying. Husk looseness is an important plant characteristic that helps to speed kernel moisture loss. Other factors are wind speed and sunshine hours that contribute to field drying.
