When to Inoculate Soybean Seed in Iowa
by Palle Pedersen, Department of Agronomy
Soybean is a legume with a seed content of approximately 38 percent protein. Because of its seed protein concentration, soybean has a large nitrogen demand and continues to increase as yield increases. Total nitrogen accumulation for soybean is supplied by two sources: the nitrogen fixation and from the residual soil nitrogen pool.
Black Cutworm Treatment Options
By Jon Tollefson, Department of Entomology
As technology traits in corn seed increase seed prices and the price received per bushel increases, it is wise to consider black cutworm management in corn. Many areas of Iowa were cool and wet last spring, 2008. That weather often delayed planting and created flooded areas that had to be replanted. These conditions may have caused black cutworms to be more common than usual.

Update on Corn Plant Populations and Seed Costs
By Roger Elmore and Lori Abendroth, Department of Agronomy
Plant populations continue to increase and, unfortunately, so do seed costs. Certainly hybrids today withstand the stress of higher seeding rates better than ever before. In fact, higher seeding rates are one component that drove annual yield increases the last several decades.
Corn Planting Begins
By Roger Elmore and Lori Abendroth, Department of Agronomy
As of Sunday, April 19, six percent of Iowa's corn sits in Iowa's fields imbibing moisture and experiencing the beginning of the germination process. In our planting date research trials, corn planted during the first week of April has sprouted with a one-fourth inch root emerged. The season begins!
April 20 Iowa Crop and Weather Report
By Doug Cooper, Extension Communications and External Relations
Doug Cooper's April 20 crop and weather report guests this week are Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope and soybean agronomist Palle Pedersen.
Taylor talks of La Niña's continued comeback having reached the SOI category, considered a significant weather phenomenon. Planting weather looks good for Iowa the next couple of weeks, but the Eastern Corn Belt may not be as fortunate.
