Green stem syndrome in soybeans
Green stem syndrome in soybean is a condition where the stem remains green while the seeds are mature and ready to harvest. In parts of Kansas, there are fields of soybeans with brown pods but green stems. Harvesting soybeans with green stems can be challenging.
Cover crop response to herbicides
Cover crop response to herbicides will be influenced by a number of factors, including biological and biochemical characteristics of the plant, chemical characteristics of the herbicide, and weather conditions since herbicide application. This article summarizes the response of selected fall-plantedvcover crops to herbicides applied the previous spring.
Rate of dry down in sorghum before harvest
In recent years, a common question from producers is related to the dry down rate for sorghum when approaching the end of the season. The dry down process can be delayed by low temperatures, high humidity, and high grain moisture content at black layer. Learn more in this article from KSU farming systems specialist, Ignacio Ciampitti.
Fall soil testing of hayfields and pastures
Soil testing can be done in either spring or fall on hayfields and pastures. Fall soil testing allows more time for any needed lime applications to have an effect before the main growing season begins, and it gives the producer some flexibility for planning nutrient applications. With high fertilizer prices, accurate soil tests are even more important to help save on input costs.
Tar spot of corn is now confirmed in five counties in Kansas
Tar spot of corn has now been confirmed in five counties in northeast Kansas. Tar spot lesions are black, raised and have a round/elliptical shape. This pathogen can survive in crop residue. Producers are encouraged to scout any standing corn fields. Fields with confirmed causes should be harvested last if possible to mitigate disease spread.
After harvest is the optimal time for Soybean Cyst Nematode sampling
Soybean cyst nematode (SCN) is a major problem in soybean fields throughout eastern and central Kansas. It is important to monitor SCN levels regularly to determine if management strategies, such as variety resistance and crop rotation, have been successful. Free SCN testing is available through the KSU Plant Disease Diagnostic Lab. Find out more in this article.
