Soybeans will reach final maturity with high seed water content, moving from 90% to around 60% from beginning of seed filling until final maturity. What factors control the dry down rate in soybeans?
Green stem syndrome in soybean is a condition by which the stem remains green while the seeds are mature and ready to harvest. Find out the best management options in this article.
Find out what insects are still buzzing around crop fields in Kansas in this article from K-State Extension Entomology.
Be ready for the 2020 growing season with these three updated crop management publications from the Department of Agronomy and K-State Research and Extension. These comprehensive guides are written specifically for Kansas and contain valuable agronomic information.
Sudden Death Syndrome (SDS) is a disease that affects soybeans and is caused by a soilborne fungus. Since there are no varieties that offer full resistance, seed treatments are a common management practice. Read about a recent K-State study evaluating a new product for the 2020 growing season.
Controlling marestail in soybeans continues to be a big challenge for Kansas no-till producers. Application timing and weed size are critical factors for successful control of this weed that germinates in the fall or early spring.
Compared to other summer crops, soybeans remove significant amounts of nutrients per bushel of grain harvested. They need an adequate nutrient supply at each developmental stage for optimum growth. Read more about the key nutrients for soybean production.
Planting date is one of the primary management practices that can greatly influence soybean yield potential. Learn more about the Kansas planting dates and maturity groups for soybeans.
The optimum seeding rate is one of the most influential factors for increasing soybean profitability as seed cost is one of the most expensive inputs. Read more from Cropping Specialist Ignacio Ciampitti in this article.
There are still many questions about row spacing for soybean production. This article summarizes some research from K-State on the effect of different row spacing on soybean yield.
Recent heavy rainfall in portions of Kansas may have resulted in standing water and/or saturated soil in some locations. These conditions have the potential to negatively impact soybean production. Read more here from Cropping Specialist Ignacio Ciampitti.
While soybean planting is tracking ahead of last year in Kansas, there are still some areas yet to be planted. What management strategies should be considered when planting soybeans later in the season?
The 2020 planting season for soybeans has moved passed half the acreage and is ahead of both the five-year average and the 2019 season due to favorable weather conditions in many Midwest states.
This article briefly outlines new information from the EPA concerning the cancellation order of dicamba made by the Ninth Circuit Court of Appeals. More information will be coming as it becomes available.
On Wednesday, June 10, the Kansas Department of Agriculture provided clarification of the impact of the EPA cancellation order for Engenia, FeXapan, and XtendiMax product labels.
It is that time of year again for post-emergent applications of Engenia, Fexapan, and Xtendimax on dicamba-resistant soybeans. In light of the recent court ruling, it is vital that application restrictions are followed closely to prevent non-target dicamba injury to conventional, Enlist, and Liberty Link soybeans.
This time of year, soybeans may begin showing signs of chlorosis or other leaf discoloration. There may be many causes for this discoloration. Nutrient deficiencies are one possibility. Learn how to identify some of the more common deficiencies in this article.
When crop fields appear variable, producers often wonder if the variability is related to nutrient status. Plant analysis can be an excellent tool for monitoring nutrient levels or diagnosing problems. Learn more in this article.
What diseases are cropping up in corn and soybean fields this summer? For corn, most fungicide applications have been made, except for late-planted fields. Soybeans are generally looking good. Read more about what diseases have been found in soybean fields.
Many producers like to estimate the yield potential of their soybeans well before reaching the end of the season. This article discusses two different methods for estimating soybean yields at this stage of the growing season.
There is still quite a bit of yield to be defined for soybeans in the next month. With most of the crop entering seed filling, weather conditions will be critical with respect to final seed weights.
What are your 2021 planting intentions for soybeans? Do you have 5 minutes to complete a survey to help guide fall and winter extension programming? If so, please complete this survey!
Soybeans reach final maturity at a relatively high water content. Dry down rates depends on a few factors such as the maturity group, planting date, and environmental conditions at the end of the season.
XtendFlex soybeans gained approval for use in the U.S. for the 2021 season. XtendFlex soybeans allow over-the-top application of glyphosate, specific dicamba-containing herbicides, and glufosinate (Liberty).
Soybean harvest is well underway in parts of Kansas. Don't forget to showcase your high yields! All soybean growers are invited to participate in the 2020 Kansas Soybean Yield and Value Contests. Read more about how to enter in this article.
Game theory is an economic tool that can be used to understand decision making in circumstances where uncertainty exists. This article examines the outcomes when applying game theory to farmers' decisions related to soybean weed management.
In general, disease pressure was lower than normal for corn, soybeans, and grain sorghum. The dry weather at critical growth periods contributed to lower incidences of yield-limiting diseases. Read more in this article from Extension Plant Pathology.
Two soybean publications have been released and are available online. Kansas Soybean Management has been updated for 2021. Also, a new study on the relationship between yield and soybean seed composition is also available.
