WHEAT PLOT DATA

We have planted wheat demonstration plots in cooperation with Kansas State University Extension for more than thirty years and have hosted plot tours every year. Plot data will be added as construction of this page continues.

Results of 2007 Plot

It should be noted that later planting dates resulted in later maturity at harvest this year due to the early coolness in the fall and late warming in the spring. Fall and spring growth was delayed in the later plantings and when the heavy rust infestation occurred in June the later maturing varieties were damaged more because leaf area had been lost. The variety in the field around the plot planted 10 days earlier yielded 19 bpa more in the field than in the plot.

Planted: September 30, 2006

Results of the 2006 Plot

Precipitation was adequate to produce an excellent crop but high temperatures in June reduced the test weights. Many varieties were damaged by wheat streak mosaic.

Results of the 2005 Plot

The 2005 plots probably had the widest variation in yields we have ever seen. Russian wheat aphids showed up early, stripe rust hit susceptible varieties hard and even infected the heads. Nearly all varieties showed symptoms of leaf rust. Tam 111 had the best leaf health of all varieties. The temperature reached 104 degrees one day about a week before harvest and affected test weight.
