Interpretive Summary:

Technical Abstract: Research was initiated to provide additional options for more economical production of soybeans in the presence of soybean cyst nematode. Soybean cyst nematode (SCN) egg population density and yield were measured in conventional tillage and no-tillage plots and under narrow (7 to 8"), medium (14-15"), and wide (28-30") row spacing within each of the tillage regimes and in the presence of SCN resistant or susceptible soybean germplasm. Additional data collected were soil nutrients (macro and micronutrients), plant tissue nutrient levels (at R4), and incidence and severity of other diseases present. The data were analyzed over all locations and also by location. Square root transformation was used to normalize combined yield data and the yield data from the individual states except for Wisconsin and Illinois where no transformation successfully reduced the variability. Log-transformation was used with the soybean cyst nematode egg population data.
