TSM 2001 Research Plots

By Randy Simonson, Ph.D.
Technical Services Manager

Yields were pretty good this year on the Catlin Research Farm.  It was looking like an exceptional growing season until the weather turned a little dry in August.  We actually had some corn that was curling (not the Olympic sport).

The TSM A budget came out on top with an average yield of 191 bu./acre.  After TSM A  came TSM E, then Conventional, U of IL, Tri-State and finally TSM I.   The TSM I is a very low budget, which does not have much fertilizer applied to it.  However, it still did very well on the soybeans.  While TSM A did the best and TSM E did slightly less, TSM I was third and it tied or bettered all the other treatments.

Looking at the nine-year averages for this research farm, we see the TSM E averaging better than all other treatments.  However, in the last four years, TSM A has done the same or better than TSM E on corn.

We also had a research plot on one of our rented farms.  This plot compared TSM E to HeadStart. HeadStart is the same, as TSM except it does not have the micronutrients in it. Adding the micros produced 9 bu./acre more corn.
