No-tillage, Strip Tillage, Chisel Plow Tillage Trial

Farmers in central and north central Iowa are often criticized for low adoption of no-tillage. No-tillage is often faulted with cooler, wetter soils and subsequently reduced yields. An alternative to conventional tillage and no-tillage systems is strip tillage where the benefits of both may be combined.

Evaluation of the Newly-developed, Least-cost Experimental Diet for Bluegill at Commercial Densities in Ponds

A substantial need exists to reduce costs and develop more nutritionally adequate diets for established as well as emerging aquaculture species in the North Central Region (NCR). The study evaluated a diet for juvenile northern bluegill (Lepomis macrochirus) that is significantly less costly than currently available diets for sunfish, while yielding a growth rate that is at least equal to an industry standard sunfish diet. Such a diet formulation is now available to the NCR as the result of a recently funded North Central Regional Aquaculture Center (NCRAC) project.

Drought Tolerant Corn Strip Trial

The strip trial was designed to evaluate new drought tolerant corn hybrids for yield. Three of these drought tolerant hybrids were planted with other hybrids for comparison.
