Overnight low temperatures the morning of October 16th reached into the low 30s (Fahrenheit), bringing an end to the growing season for a lot of vegetation across Indiana (Figure 1).

While we often focus on the importance of yield monitor calibration relative to logging accurate yield estimates during grain harvest, there are other yield monitor settings that can inadvertently influence yield estimates.
Geo-positional inaccuracies in DGPS signals affect the accuracy of yield monitor data in various ways.
Frogeye leaf spot (FLS) is becoming a serious threat to soybean production in Indiana and surrounding states. Traditionally a southern disease, it can cause yield loss up to 60%. In recently years, FLS severity has been on the rise in the North Central region. It caused estimated yield loss worth $51 million in Indiana and $428 million in the North Central region in 2018. FLS infection can occur at any stage of soybean development, but most often occurs after flowering. Initial symptoms are small, dark spots, which will eventually enlarge to a diameter of up to about ¼ inch. The centers of the lesions become gray to brown and have a reddish-purple margin. Stems and pods can also be affected later in the season. Symptoms on stems are long narrow dark lesions with flattened centers. Pod lesions will be circular to elongate, slightly sunken and reddish-brown. Seed symptoms will appear[Read More…]
Switchgrass (Panicum virgatum L.) is a native perennial warm-season grass that is adapted as many ecotypes across North America.
Even if grain yield monitor calibration, adjustments, and operation are faithfully conducted (Luck & Fulton, 2014; Nielsen, 2020c), the resulting yield data sets almost always require some post-harvest processing and “cleaning” procedures to rid the data set of anomalies and “gremlins” (Luck et al., 2015; Nielsen, 2020a; Nielsen, 2020b).
All programs/events are being tweaked during this new “normal,” hoping you will join us for the virtual 2021 Crop Management Workshop.
We had some chilly nights last weekend and the beginning of the week, which caused concern for some hemp growers. But, we made it through and the hemp seems to be doing alright. There are some noticeable changes in color, which could cause alarm, other than that, the hemp is unscathed. One cultivar at Meigs went from a bright green to a deep purple. The same thing happens to the forsythia in my front yard and to many other plants this time of year. Most of the data on frost tolerance and hemp is out of Canada and focuses on grain and fiber specific cultivars. Growers have harvested all the fiber hemp and most of the grain hemp. However, there is not much data on frost tolerance in cannabinoid rich hemp. The University of Vermont does have some useful information on their experiences with frost and hemp. They find that[Read More…]
Harvest is already underway in the Midwest with 22% of corn and 30% of soybean already harvested in Indiana by October 4 according to USDA-NASS crop progress report (USDA, 2020). It appears that the yields this year would be fairly good and farmers would be bringing in a good crop. This article focuses on securing the crop by ensuring that grain is harvested timely, dried adequately and binned correctly. Harvest grain timely and dry adequately for safe storage First of all, it is important to know what moisture content you need to be storing your grain at based on your short and long-term marketing plans. How long you intend to store your grain will determine the level of moisture content to dry your grain to. Table 1 provides a guideline on recommended maximum moisture contents at storage periods from up to 6 months to over one year for[Read More…]
Combine fires cost farmers millions of dollars in damages every harvest, and in dry years such as 2020, the potential for fires is even greater than normal.
