Effect of Inoculation of Soybean Seed on Yield

The soybean, being a legume, has the capacity to form root nodules and to fix nitrogen from the air. Rhizobia bacteria must be present for the soybeans to fix nitrogen. Because of the development of new strains of rhizobia and the new formulations of inoculants, a study was conducted to test whether a seed-applied inoculant, Sow-fast, would increase yield

Developments at Northern Research and Demonstration Farm

The south site was originally acquired to study tile drainage, and had tile at different depths and spacings. Some of these spacings and depths were not adequate to drain areas well. To provide adequate drainage in these areas 2,500 feet of tile were installed on the south site. On the north site 1,300 feet of tile were also installed. As agriculture changes over time so do questions about agriculture. To better answer these new questions several research projects were changed or added. The cottonwood breeding work and the soybean cyst nematode research on the farm were doubled. A popcorn breeding experiment was conducted. Chicken manure was applied to several farms in the area. To study the effects of chicken manure on corn yields and soil fertility two experiments were begun

Impact of Driving over Soybean Plants on Yield

With the development of narrow row soybeans, and postemergence herbicides that can be applied several times, and with the practice of spraying for late developing insect problems, the question arises of how late can soybean plants be driven over before yields are reduced. To answer this question an experiment was conducted in 2002 and 2003 on the farm
