Minnesota CropCast - Seth Naeve: Promoting Minnesota Soybeans Abroad
(2023-06-20) Nicolai, David; Naeve, Seth
This week’s special guest is also co-host, Soybean Agronomist Dr. Seth Naeve. Seth talks about why he traveled to Indonesia last week and what makes Indonesia relevant to farmers from the upper Midwest. Seth spends about half of his research and extension efforts on soybean quality. He regularly travels to North and Southeast Asia to meet with soybean importers, feed millers, animal nutritionists, and other end-users. His primary message is that protein is not a good indicator by itself of soybean or soybean meal quality and does not determine the value of these feed ingredients for most purchasers whereas amino acid content and other factors need to be considered when purchasing soybeans. His goal is to increase demand for soybeans produced in the Western Corn Belt to support local soybean prices for farmers.

Minnesota CropCast - Corn and soybean update from Jay Zielske and Jared Goplen
(2023-10-03) Nicolai, David; Naeve, Seth
In today’s CropCast, Seth Naeve and David Nicolai welcome veteran regional agronomists, Jay Zielske and Jared Goplen. Jay works for Corteva in south central Minnesota, while Jared works for Wyffels Hybrids covering western Minnesota, northwest Iowa, and a few counties in South Dakota. These two gentlemen shared their observations on harvest progress and reported yields in their areas. One cannot discuss variable yields in 2023 without a focus on what brought us here. Planting delays, poor stands, and a chronic drought stressed the crops. In contrast, plant diseases tended to be reduced. If yields are slightly better than anticipated, where did those bushels come from? Jay and Jared also provided advice on selection criteria when ordering 2024 corn and soybean seed inputs.

Dr. Tom Peters is a sugarbeet agronomist specializing in weed control at North Dakota State University and the University of Minnesota, Zach works for Pioneer/Corteva in Northwestern Minnesota as a regional agronomist and researcher. These two gentlemen reviewed the crop growing season and early harvest results for sugarbeets, corn and soybeans in western Minnesota. They discussed early planting delays, limited seasonal rainfall, weed concerns and why some early yield results were better than expected. Factors such as genetic improvement and cultural management contributed significantly to the improvement for some area yields. Tom and Zach also provided advice on 2024 selection criteria when ordering corn and soybean (SCN tolerance) inputs as well as pest management & crop rotation of sugarbeets, corn and soybeans.Please join us for another lively Minnesota CropCast.
Minnesota CropCast - Corn and Soybean Variety Selection for 2024 with Drs. Jeff Coulter and Dean Malvick
(2023-10-18) Nicolai, David; Naeve, Seth
In this week’s MN CropCast, Seth Naeve and David Nicolai welcomed University of Minnesota Extension Specialists; Dr. Jeff Coulter and Dr. Dean Malvick. Coulter is an Extension Corn Specialist and Malvick is an Extension Plant Pathologist specialist for corn and soybeans. These state specialists discussed the selection criteria for growers to consider when choosing their 2024 corn and soybean seeds. While crop yield data from multiple sites in 2024 is extremely important, yield stability over time and environments is essential in the selection process. Dr’s Coulter and Malvick also provided advice on 2024 agronomic selection criteria when ordering corn and soybean seed such as corn standability, tolerance to diseases and drought plus other agronomic factors along with soybean disease resistance, iron chlorosis and SCN tolerance. Both specialists emphasized that knowing individual field histories which detail past disease occurrences, crop rotations, fertility, soil types and yields is critical in making final variety selections.Please join us for another lively Minnesota CropCast.

Minnesota CropCast - Dr. Kelsey Anderson Onofre: Kansas Wheat, Fusarium Head Blight, and the US Scab Initiative
(2023-11-01) Nicolai, David; Naeve, Seth
In today’s CropCast, Seth Naeve welcomes, Dr. Kelsey Andersen Onofre, an Assistant Professor and Wheat and Forage Extension Specialist in the Department of Plant Pathology at Kansas State University. Kelsey is joining us through a collaboration with the US Wheat and Barley Scab Initiative, a national multi-disciplinary and multi-institutional research consortium whose goal is to develop effective control measures that minimize the threat of Fusarium Head Blight (scab) for producers, processors and consumers of wheat and barley. USWBSI funds over 150 research projects in 30 American states. You can learn more at scabusa.org. Kelsey discusses the 2023 wheat crop in Kansas and highlights the drought impacts on production. Seth and Kelsey chat about the impact of wheat scab and it’s presence in years like the current one. They discuss the impact of Fusarium Head Blight and the economic impacts. Management through variety selection and fungicide application is possible, but it can be especially challenging for producers in areas with either infrequent challenges from Scab or low yielding environments where intensive management can be economically infeasible. Please join us for another Minnesota CropCast.
Minnesota CropCast - University of Minnesota Soybean Research Center: Graduate Student Spotlight
(2023-11-08) Nicolai, David; Naeve, Seth
In this special cross-over episode, CropCast hosts Dave Nicolai and Seth Naeve visit with three talented graduate students who work on Soybean Research Center related projects. Mary Jane (Mjay) Espina is a PhD student with Aaron Lorenz and Bob Stupar. Mjay is focused on Iron Deficiency Chlorosis (IDC). She is primarily interested in identifying the source(s) of resistance to IDC within soybean’s genome. She hopes that understanding the genetics behind IDC will help her and us learn more about the physiology driving this disorder. Alina Smolskaya is an MS student who is also advised by Drs. Stupar and Lorenz. She is working on the genetics of very interesting soybean traits related to leaf shape and seed number per pod. Leaf shape can play a role in whole plant photosynthesis and therefore productivity, and seeds per pod is an important yield component. Master’s student Carlos Sanchez also joined the discussion. Carlos is advised by Seth Naeve and his work has been conducted at a unique drainage and tillage research site near Wells, MN. Carlos is interested in the environmental drivers behind yield benefits from drainage and has noted that very dry years can reduce or reverse benefits to artificial drainage. Carlos is also looking at interactive effects of tillage, residue levels, soybean populations, seed treatments, and nitrogen carryover on drainage effects. Have a listen to this special edition of MN CropCast. You will appreciate the passion of these young scientists.
