    Creating a System for Optimum Corn Yields

    February 25, 2021

    Posted by Stine Seed in Crop Management

    Stine® offers a full spectrum of high-yielding corn products in a range of maturities to ensure growers have the right fit for their field type and growing conditions. Our unique, conventional genetics are paired with the industry’s leading trait packages to achieve outstanding performance. Our products alone will provide you the means to achieve high yield, but treating your corn program as a system and not simply as a product can help you achieve maximum, if not record-setting, yields.

    As our corn research evolves, so does our understanding of what management practices help produce maximum yields. The first step to achieve yield is choosing the right product for your fields, but growers can implement more to get the most bang for their buck come harvest — a system of best management practices, so to speak. Based on our multi-year research, we encourage growers to follow this checklist of best management practices to achieve optimum corn yields.  


    • Choose the right hybrid. This step is perhaps the most important management decision. While we stand behind every Stine corn product, we encourage growers who have productive soils and optimal conditions to consider choosing a product suited for high-population planting. Because our HP Corn® products have outstanding roots and stalks for excellent standability and are designed to capture more nutrients and sunlight, they thrive in high-density conditions.
    • Check soil fertility. Nutrients like sulfur and nitrogen are vital to the success of a crop. Before growers begin planting, they should consider soil sampling to ensure they have adequate nutrients for their crops. Our Stine sales reps are available to help determine the appropriate amounts of fertilizer for our specific corn products.
    • Prep the planter. For optimal outcomes come harvest, growers need to plant the seed at the right rate at the right depth. For variable rate or precision planters, calibrating software will ensure everything is programmed properly. Checking the meters and field-mapping software is important as well. You should also check for common signs of wear and tear and ensure all seed tubes are in good shape. Gauge wheels should also be checked to make sure the row units will have the proper contact with the ground. Prepping your planter will give you a head start to ensure proper seed placement and desired populations are achieved come planting time.
    • Check soil temps. It is recommended that soil temperatures reach at least 50 degrees for three or more consecutive days before planting to ensure good germination and emergence. Avoid planting into cool, wet and water-logged soil, which can lead to poor seed to soil contact, among other problems.


    • Plant early, if possible. When field conditions are right, plant as early as possible. Delayed planting results in bigger plants that take up more room and require more nutrients, which increases the need to lower populations. The earlier you can plant, the higher you can push populations. If planting is delayed, Stine sales reps are available to discuss how to adjust populations down.
    • Plant at the appropriate range. Growers planting in highly productive soil should plant at the 41,000 to 51,000 range, with the high-end of the range restricted to products that include HP genetics. If high-population planting is not an option, plant populations are recommended between 32,000 to 34,000.
    • Try narrow rows. We’ve said it before, and we’ll say it again: narrow rows are the way of the future. Our products are bred so that growers can achieve higher yields by pushing populations and narrowing rows. Growers who traditionally plant 30-inch rows might consider transitioning to 20-inch rows this planting season. If you have a 15-inch soybean head, you might consider testing your corn in 15-inch rows by swapping your soybean head for a 15-inch corn head come harvest. Consult with your local Stine sales rep on the advantages of narrow-row corn.

    Growing Season

    • Consider a side dress. For higher populations, ideally, you’ll want medium to high levels of phosphorus and potassium combined with the appropriate amount of nitrogen and sulfur. These levels can be achieved by applying the appropriate nutrients during the growing season as a side dress or over-the-top application. In-season applications should always include sulfur.


    • Harvest early. When possible, harvest early to reduce yield loss. Getting the crop out of the ground in a timely manner will help minimize yield loss caused by lodging, ear loss, cylinder loss, separation loss and header loss from being too dry.

    We know this to be true — any corn product on the market has the best opportunity to achieve its full potential when it’s approached as a system and not simply as a product. Our years of research and data back this recommendation. Consider this, switching to narrow rows with more equal planting distance can result in yield gains of three to nine percent. Selecting the right product with our HP Corn genetics can translate to a five to 12 percent yield increase. Ensuring your soil has the proper nutrients, as well as timely nitrogen applications, may result in a 10 to 20 percent yield boost. Before you hit the fields this spring, keep these recommendations top of mind. And when in doubt, your local Stine sales rep is available to lend a helping hand.

    Yield Plus Performance with Stine® Brand Enlist E3® Soybeans

    February 18, 2021

    Posted by Stine Seed in Products

    Thinking back to 2020, our line of Stine® brand Enlist E3® soybeans had outstanding performance that is worth highlighting again. From the Delta South to the upper Midwest and the East Coast, the range of maturity options ensured that no matter the territory or disease and insect pressure, growers had an Enlist E3 soybean product that worked for their situation. Over the past several months, our Agronomy team and regional sales agronomists have shared the feedback they’ve received about these products, including some of the lines that have shined in their regions.

    Outstanding Products
    In the northern Corn Belt, Stine Corn Technical Agronomist Tony Lenz noted they had “numerous, consistent high-yielding Enlist E3 soybean varieties.” Some that stood out included Stine 06EC23, 12EB32, 24EA12 and 34EA12. These products all showcased very good emergence and standability and are also high-end yielders in our Elite Yield Trials. 

    Bill Kessinger, corn technical agronomist for our eastern sales territory, said that Stine 24EA12 and 34EA12 also performed well in the northern half of his region, from Ohio and Indiana to Michigan and Illinois. In the southern half of Bill’s territory, growers saw success from Stine 39EA02 and 41EA12, which continue to be top yielders for our customers. They also boast great disease packages, with added protection against Phytophthora root rot, SCN and stem canker, to name a few.

    “The Enlist E3 platform as a whole was impressive, and we did have a couple of standout hybrids and varieties that worked across the different conditions … all handled those stress situations tremendously and packed a yield punch,” Bill reflected.

    Stine RSA Kevin Krabel saw similar success with Stine 27EA23, 34EA12, 36EA02 and 39EA02. In fact, one grower in central Illinois told Kevin that Stine Enlist E3 soybeans performed “as good or better across the board” than any of the Asgrow® Xtend® soybeans he planted last year.

    Dustin Ellis, our regional sales agronomist for central and southcentral Iowa, was very pleased with how Enlist E3 soybeans handled stress situations throughout the state, which ranged from a mid-season derecho to a late-season drought. A few of these products have performed well year after year.

    “Our top-yielding Enlist E3 soybeans last year were Stine 19EA33, 21EA32, 24EA12 and 27EA23. Stine 19EC32 and 19EC33 are looking outstanding and are some of our new C-series soybeans that need to be considered for 2021,” Dustin noted.

    Katie Lorenz, our regional sales agronomist for northeastern North Dakota, noted they saw record yields in her region in 2020, in particular with Stine 01EA63 and 03EB02, which are earlier maturity soybeans that have generated buzz in the northern Corn Belt.

    “Stine 01EA63 and 03EB02 have been knocking it out of the park with yields in the 60s,” said Katie.

    And in south-central Nebraska and southwestern Iowa, RSA Chad Kuehl saw “exceptional” yields, especially on irrigated grounds. “We saw multiple plots with the average above 90 bushels/acre,” Chad reflected.  

    It’s clear that Enlist E3 soybeans have exceeded expectations across the industry. With elite, high-yielding genetics and outstanding weed control based on built-in tolerance to three sites of herbicide action — 2,4-D choline, glyphosate and glufosinate (Liberty®), all of which are approved and readily available for 2021 — Enlist E3 soybeans will offer growers top-end yield potential this growing season.

    Stine® Conventional Corn Offers Yield Plus Savings

    February 11, 2021

    Posted by Stine Seed in Products

    Over the years, Stine has developed partnerships with the industry’s leading breeding programs. These collaborations benefit both us and our grower customers. They give us access to top-tier genetics, which allows us to test more genetically unique lines of corn and to bring newer, higher-yielding conventional corn products to market faster and more efficiently than our competition. This unique position has also provided us the opportunity to develop our breeding program based on the newest conventional genetics so that we can offer grower customers more choice and better yield potential.

    Developing the industry’s highest-performing seed starts with a solid foundation, and the foundation of our seed corn is conventional genetics, with traits to follow. However, not every situation calls for a trait. In some instances, if your fields aren’t at an increased risk of above- and below-ground pests or if you’re not too worried about heavy disease pressure, spending extra money on traited corn may not deliver the best return on investment for your fields.

    Stine’s conventional corn products allow you to save money without jeopardizing yield potential. Our line of conventional corn seed has passed rigorous testing in our extensive breeding program, so you’re not losing quality or yield potential when you choose our conventional corn. 

    We’re pleased to offer growers several conventional corn lines for the 2021 season, a few of which are:

    Stine 9002-0 Brand Corn — A 77–79-day relative maturity product with high-yielding conventional genetics. This product offers excellent emergence with late-season stalk strength for maximum standability. This is a great option for productive soils as a full-season hybrid.

    Stine 9714-0 Brand Corn — A 105–107-day relative maturity product and proprietary hybrid to Stine’s breeding program, Stine 9714-0 is a shorter type hybrid with an average 89-90-inch plant height. This allows growers to push populations and maximize sunlight interception for more yield. This product has a deep root structure for better standability and moisture intake and is one of the leading high-population corn options in the industry. Stine 9714-0 works well on highly productive and loam soils. 

    Stine 9709-0 Brand Corn — A 110–112-day relative maturity product, Stine 9709-0 is a taller version of our high-yielding 9714 brand genetic family. With strong roots and stalks, this product can handle variable soil types and works well in any row configuration. It also has a positive response to higher populations.

    Stine 9808E-0 Brand Corn — A 114–116-day relative maturity product featuring excellent roots and stalks. Stine 9808E-0 offers very good disease protection against gray leaf spot, S.C. leaf blight and Goss’ wilt, and works well in all row widths and thrives in loam to clay-loam type soils.
