These variety trial reports contain statistical information that is critical for proper interpretation of the data. However, without basic understanding of statistics, growers and end-users of the variety trial reports may misinterpret the data and draw invalid conclusions. This fact sheet addresses basic statistical concepts and how to apply them to properly interpret variety trial data. Authors: Andrew A. Kness and Nicole M.

Actual Production History (APH) is a 4- to 10-year yield average used to calculate each producer’s production guarantee. Producers with 10 years of yield history are penalized under APH because yields have increased over time, and APH yields can lag behind their most recent yields. Therefore producers with only 4 years of yield history can actually have higher average yields.
