The Turkey Hard Red Winter Wheat brought to Kansas by Mennonites in 1874 quickly became the most important crop in the state. Continued improvements by breeding and modern technology for production have kept Kansas the number one wheat state in the nation. Hard Red Winter Wheat has stayed important for so long because its traits and pattern of growth and development are best suited of all crops to the weather, soils, and other conditions in the state. However, weather in Kansas is less than ideal for wheat and, more than any other factor, limits grain yields in the state. Wheat growers in Kansas are highly knowledgeable and the soils are generally excellent, but grain yields are only a fraction of the 100-plus bushels per acre averages in some countries. The weather also limits the production inputs — the seeding rate, fertilizer, and pesticides — that can be used economically for high Kansas wheat yields.

This section is intended to provide you with the information needed for your wheat crop.

Estimating Wheat Yields

Estimating Wheat Yield Tool

Helpful equations to estimate wheat yield in Western Kansas:

Yield estimated before heading (bu) =((stems per foot x 0.531 + 8.5)x 0.531 / row spacing (inches)) x 19.213

Yield estimated after heading (bu) = (heads per foot x 0.513) / row spacing (inches)) x 19.213

Adjustments to yield: Replace the coefficient 0.513 with 0.409 for a poor year or 0.618 for a good year.
