Deciding when to plant soybean is an important management decision that greatly impacts yield. This publication discusses the potential yield increases from early planting and potential yield loss from delayed planting.Mark A. LichtDavid WrightAndrew W.

Biology and Management of Soybean Diseases Increasing in Importance to Iowa Soybean Production Different plant pathogens have different environmental requirements for growth and survival. As the weather changes from season to season, so does the prevalence of certain pathogens. This natural cycle results ...
This aphid was first found in Iowa in 2000 and has since been reported in every county; however, little information is available concerning its impact on the prevalence and incidence of SMV. The middle leaflet of the topmost fully-developed leaf from each plant sampled from a soybean field ...
In the latter case, it is known as the so-called biological nitrogen fixation (BNF) process. Each of these nitrogen sources has an important role in plant growth and development [1]. However, biological nitrogen fixation is the most significant process that allows for obtaining high and good-...
Soybean is often grown in close proximity to other field crops and wild plant species [10]. Thrips can inhabit a wide range of plants, and various plants can act as reservoir host plants of both the vector and virus [11,18]. Information about SVNV and thrips alternative hosts is lacking...
(Aphis glycines)can be a major pest for soybean growersin Iowa. In 2003 aphid populationsexceeded 3,000 aphids per plant in manyfields. During this year, Iowa soybeanyields averaged 32 bushels per acre—a 16 bushel per acre (or a 32%) reductionfrom 2002. This yield reduction was partly...
