Phyllis Bongard, Extension content development and communications specialist, Candy Hirsch, Professor, Department of Agronomy and Plant Genetics , and Tom Hoverstad, Researcher, Southern Research and Outreach Center What does the use of big data in corn genomics mean for today’s producers? Dr. Candy Hirsch, a corn geneticist and genomics professor, and Tom Hoverstad, Researcher at the Southern Research and Outreach Center, described how sequencing DNA can lead to improvements in corn production in the January 24 Strategic Farming: Let’s talk crops session. Generating big data in corn genomics How can big data help maximize yield increases in corn? As corn genomic data expands, it will ultimately allow plant breeders to predict performance for a very large number of progeny without having to grow every individual in every field environment. Dr. Hirsch’s Maize Translational Genomics lab at the University of Minnesota generates big data to study these relationships between corn genetics,

By: Taylor Herbert, Extension Educator, Crops - Wright, McLeod, & Meeker Counties; Dr. Vasudha Sharma, Extension Specialist-Irrigation; Brenda Postels, Extension Educator Over the past few years, efficient agricultural irrigation has become a hot topic in Minnesota. With its sandy soils and limited precipitation, irrigation is a key component of production agriculture in the central region. Combined with these conditions and the limited and varying rainfall we have been experiencing, matching irrigation with crop water use has become more important. An understanding of the plant-water-soil relationship, proper irrigation system maintenance, and use of irrigation scheduling are just some of the tools irrigators use for cost-effective crop production. If you want to improve your irrigation use efficiency, the University of Minnesota Extension is offering the Minnesota Irrigator Program (MIP) to provide you with the information you need to make irrigation decisions in 2024.

In episode #27 of Minnesota CropCast, David Nicolai and Seth Naeve sit down with Jim Anderson from the Department of Agronomy and Plant Genetics at the University of Minnesota. As the spring wheat breeder, he has released at least 19 cultivars and co-developed 8 more. Jim is well known in the small grains communities. He speaks regularly with farmers and commodity organizations and is a leader in the wheat breeding community.   Jim is a pioneer in breeding technology with research focused on identifying genes underlying economically important traits and implementing marker-assisted and genomic selection for cultivar and germplasm development. In addition to wheat, he leads plant improvement programs focusing on intermediate wheatgrass (Kernza®) and field pennycress. He is also an extremely active advisor for graduate and undergraduate students and teacher in the classroom.  Please join Dave and Seth for a conversation about breeding established and developing crops for Minnesota on t

Nitrogen continues to receive a lot of attention from farmers and the ag industry as a whole. Between the high fertilizer prices experienced over the past few years and environmental issues, there is a lot to consider when making N management decisions. Building on the popular Nitrogen Smart program, University of Minnesota Extension will host two free “Nitrogen College” events January 30-31 at the Shooting Star Casino in Mahnomen and February 5-6 at Jackpot Junction near Morton. Both events will feature five sessions over two days. Attendees can choose to attend any or all of them. As usual, there is no cost to attend thanks to the support of the Minnesota Corn Growers and pre-registration is not required. The five sessions are: “A Deep Dive Into the 4 Rs” – 9am on first day – This curriculum goes into detail about the different types of N fertilizer and how they are best managed. This session includes a detailed look into determining the best rate for a field in a specific year. “

Regenerative agriculture, resilient cropping systems, and soil health are just a few of the buzzwords that are busied a lot these days. One of the simplest and fastest ways to accomplish many of the goals that these concepts set out to accomplish is extending your crop rotation beyond the corn-soybean rotation that dominates much of Minnesota.  Can spring or winter wheat, hybrid winter rye, or oats be that third crop? And if so, what does it take to end up in the black with that third crop at the end of the year? The University of Minnesota Extension is offering small grain workshops across Minnesota in February to address successful small grain management. Workshops will focus on production agronomics, variety selection, and economics, and will include an open-forum discussion for related topics and on-farm experiences. These workshops are sponsored by the Minnesota Wheat Research and Promotion Council. We ask that you register online (https://z.umn.edu/GrainUpdate) for these free wo

Craig Sheaffer, Extension forage agronomist  Alfalfa grown in contour strips with corn. Alfalfa and perennial grasses are among the best year- round living cover crops. Source: NRCS, USDA A recent study entitled “ Putting Down Roots: Analyzing the economic and environmental benefits of continuous living cover for Minnesota’s farmers, water and climate ”  has shown the environmental and economic impacts that alfalfa and perennial grasses have as continuous living covers (CLC). Other new CLC crops are being developed within the Forever Green initiative  at the University of Minnesota to diversify our predominant summer annual cropping systems. The crop categories that were analyzed for environmental and economic potential include: Perennial forage and pasture (alfalfa, cool and warm season grasses) Perennial grains (Kernza, perennial wheat, etc.) Winter annual oilseeds (winter camelina, pennycress) Winter annual cereals and legumes (hybrid winter rye, winter pea) Woody perennials (haz

Craig Sheaffer, Extension forage agronomist Seed coating adds weight and color to seed. The yellow seed is uncoated. Today, seed coatings are widely used on forage legumes and some grass seeds. The overall goal with seed coatings is to improve germination, seedling vigor, and seedling survival. They also increase seed flowability and help distribute small seeds more evenly.   Coatings vary in their constituents and coatings affect pure live seed percent within a bag as described by Newell (2018) and Hayward (2017). A 34% seed coating is widely used for alfalfa seed. Standard components include Rhizobium for nitrogen fixation and fungicide treatments for seed and seedling protection, along with binding and coating polymers, minerals, and colorants.  Many seed companies add optional treatments based on marketing strategies. These can include specialized components like growth promoters, micronutrients (Mn and Fe), mycorrhizae, insecticides, bio-enhancers, and hydroscopic materials to at

Craig Sheaffer, Extension forage agronomist Establishing a productive stand of alfalfa or other forage begins with quality seed. The seed label contains information that allows farmers to evaluate the quality and value of the seed they purchase. The seed label    Federal and Minnesota seed laws require labeling of all seed sold to farmers. This applies to a single crop or a mixture and applies whether the seed is sold on-farm or at a retail business. Information on the seed label helps growers evaluate the quality and value of the seed. They also provide for fair marketplace competition among seed suppliers. To ensure truth in labeling, the Minnesota Department of Agriculture inspects seed. Attached is a fictional/example alfalfa seed tag showing information required by the Minnesota seed laws. While all the information is important in describing the seed in the bag, there are several key items to pay attention to. A fictional alfalfa seed label. Kind The kind identifies all desired s

Phyllis Bongard, Extension content development and communications specialist, and Dr. Frayne Olson, Crop economist and marketing specialist, North Dakota State University With recent softening in the corn, wheat, and soybean markets, what is the outlook for 2024? Dr. Frayne Olson, Crop economist and marketing specialist from North Dakota State University, addressed several factors shaping the current crop market and outlook in the January 10 kickoff session of Strategic Farming: Let’s talk crops. USDA data out January 12 Crop prices softened and trade volume decreased during the “holiday hangover” leading to concern. Producers started wondering if this might be a long-term trend. What might we expect going forward? USDA released four major reports on January 12 that are closely followed by market traders and analysts in the US and around the world. They serve as a reference point and help set expectations for the markets going forward: WASDE (World Agricultural Supply and Demand Estim

By Arthur V. Ribeiro (Post-doctoral Associate) and Robert L. Koch (Professor & Extension Specialist), Department of Entomology, U of MN Since its first detection feeding on soybean in the United States in 2021, we have been keeping a close eye on this potential new pest, which now has an official common name: the “soybean tentiform leafminer”. The soybean tentiform leafminer ( Macrosaccus morrisella ) is a tiny moth native to North America where it has been known to feed on two native plants: American hog peanut and slickseed fuzzybean. However, it has recently developed the ability to feed on and infest soybean. Survey efforts have expanded to determine how widespread are the infestations of this insect in soybean. In 2021, soybean tentiform leafminer was detected in the Twin Cities Metro Area, in Ramsey and Dakota counties. In the following year, we received 12 new reports extending from the Twin Cities Metro Area to southeast South Dakota. These new reports raised concerns about

David Nicolai and Seth Naeve were fortunate to have an opportunity to chat with Dr. Rex Bernardo early in the new year. He is a Professor and Endowed Chair in Corn Breeding and Genetics in the Department of Agronomy and Plant Genetics at the University of Minnesota. Dr. Bernardo is Director of the Plant Breeding Center at Minnesota, has written two textbooks, and teaches graduate courses in plant breeding and in professional skills for scientists. Rex is a futurist and a lifelong learner. His accomplishments are a testament to his knowledge, drive, and foresight.  Rex’s work has focused around marker assisted selection in corn for nearly thirty years. This current work includes genome-wide prediction, targeted recombination for quantitative traits, and refined breeding schemes (plus a side project on sweet corn breeding). In summary, Rex has been working with big data since the data was small. In this CropCast, Dave and Seth chat with Rex about his research and his novel views on

By Dave Nicolai and Liz Stahl, University of MN Extension Crops Educators Unfortunately, pesticide applications can sometimes drift onto neighboring crops and vegetation. Damage can range in severity from brief cosmetic symptoms to the inability to market a crop, severe yield losses and/or plant death. Bee kills can also be an issue where pesticide misuse, misapplication, or drift has occurred. The Minnesota Department of Agriculture (MDA) has developed standard procedures to follow when pesticide drift is suspected.

Reports of low falling numbers in HRSW are widespread.   The Hagberg Falling Numbers test (HFN) is a measure of the amount of α -amylase in the grain. Alpha-amylase is an enzyme that hydrolyzes polysaccharides like starch into simple sugars (glucose and maltose). A low HFN test value indicates that there is a large amount of α-amylase present in the seed, resulting in a very rapid breakdown of the starch in the ground wheat sample used in the HFN test, thereby allowing the plunger to fall rapidly through the slurry in the test tube. The HFN is used as an indirect measure of sprout damage in the harvested grain. Sprouted grain is problematic as a source of seed for next season as the germination and vigor will decline over time in storage.   Likewise, milling and baking quality are also affected as the α-amylase breaks down the starch in the endosperm and over time the α-amylase present will degrade and no longer be reactive when needed during fermentation. Unfortunately, the
