    Tips for Carefully Selecting Corn Silage Hybrids

    Feature Tech Tuesday 01

    Risk reduction is one of the most critical considerations when designing your crop plan.

    Taking “calculated risks,” rather than reacting somewhat spontaneously to emotion-based marketing tactics that make us want to buy on the spot, is especially important in fragile markets.

    “I think you should buy corn hybrids for silage only from seed companies that evaluate their hybrids for silage use,” writes livestock nutritionist Everett D. Thomas in an article published November 30, 2017, by Progressive Forage magazine. “… they should have silage yield and quality data, including fiber digestibility. In some seed company catalogs, corn silage is mentioned only in passing – or not at all.”

    What a great statement — that still holds true today! There are so many things to consider when planting a hybrid: consider the end use first; keep crop rotation in mind; and minimize risk factors.

    From a plant genetics standpoint, top risk factors are moisture stress and disease pressure. Remember that healthy plants are needed in the field to produce high quality feed and top yield. The key is to strike that best balance between all critical factors, so what’s best in the field translates to what’s best in the bunk.

    Latham’s FieldXFieldSM approach to crop selection helps put the best in each field, which is part of bringing the best in the bunk. Genetics certainly play a role in delivering quality at the bunk, but that’s only one factor of many when producing silage. You also need stress tolerance and disease management, which may include a fungicide, along with good plant nutrition, and a strong plan for timely harvest.

    As an independent company, Latham Seeds has bountiful genetic options. Latham® Leafy products are a great corn silage-specific option. Sales of our leafy corn products continue to grow because they produce amazing tonnage and quality.

    NOTE: Leafy and silage-specific products typically don’t score high in university trials, as leafy hybrids perform better at lower planting plant populations and university trials are geared for higher populations. If corn silage evaluation programs were planted at the lower populations and evaluated fairly, the results would be more reliable and comparable. Many corn silage growers like the flexibility they get with dual-purpose hybrids for their utility across varying soil types and flexibility at harvest time, and trait options. If the bunk is filled, growers can still get top grain yield and sell some grain.

    Every grower’s needs and corn silage experience are unique and different. Silage-specific products don’t fit into some grower’s crop rotation based on the trait needed to reduce risk. The great news is that Latham has a full lineup of dual-purpose hybrids for those situations.

    TIPS FOR INTERPRETING CORN SILAGE DATA

    Now that most farmers have finished with harvest and fall tillage, it’s time to head inside and finalize plans for next season’s crop! Similar to corn and soybeans, YIELD IN THE FIELD IS IMPORTANT FOR CORN SILAGE. There are some additional metrics that help us compare corn silage varieties.

    Corn silage reports can get complicated, so I’ll try to simplify a few major elements:

    • Milk 2006 – an evaluation system that helps provide an energy score from a combination of Fat, Ash, Neutral Detergent Fiber (NDF), Neutral Detergent Fiber Digestibility (NDFD), Protein and Starch.
    • Milk/ Ton – The amount of milk or animal response is predicted per ton of corn silage, which directly reflects the quality of the corn silage. Higher numbers indicate better corn silage.
    • Milk / Acre – The amount of milk is predicted per acre of corn silage. It’s a combination of dry matter tons harvested and the quality of the corn silage. Higher numbers are better.

    Our goal is to provide quality information to help guide you, and your team of agronomy and nutrition professionals to help achieve best return on investment including:

    • Excellent Tonnage comes from top yields with top quality.
    • Excellent Quality is a result of hybrid selection and management. Corn Silage management practices are the most vital factor to achieving peak quality, from planting to harvest.
    • Prime harvest moisture of 65% to 70% whole-plant moisture helps ensure proper packing and fermentation, which helps reduce free oxygen and potential for mold and mycotoxin growth.

    Feel free to contact me if you need help discerning starch types or selecting the best trait package for each field. Top performance is a team effort at Latham Hi‑Tech Seeds!

    Tips for Selecting Corn Silage Hybrids

    CoreyC2One question frequently asked by producers – and rightfully so – is what the most important characteristics are when selecting corn hybrids for silage or grain. To pick the best hybrids for his situation a farmer should follow 3 basic steps: (1) Consider the end use first; (2) Keep crop rotation in mind; and (3) Minimize yield-limiting factors.

    Consider the end use first. Corn kernel attributes can vary greatly, and seed traits can affect the qualities of the end product. For example, the availability of kernel starch and how it is digested is important for ethanol and livestock feed. A softer starch kernel is not preferable for export. When selecting corn hybrids for snaplage, look for excellent fall plant intactness plus a large ear and flared husk to facilitate a cleaner ear snap. Some hybrids have better fiber digestibility than others, but you also have to make sure those particular hybrids work on your soils or have the desired trait package needed in a corn-on-corn situation.

    Keep crop rotation in mind. Crop rotation must also be considered when making seed selections. Planting corn on corn creates probable nutrient shortages, as well as increased insect and disease pressure. Residue management also helps prevent disease transmission between seedlings and old residue. Remember when corn is harvested for grain, organic matter is left in the field that doesn’t remain when the corn crop is harvested for silage or when corn stalks are baled. Different hybrids are needed when planting conventional verses no-till or minimum till situations.

    Minimize yield-limiting factors. Seed selection and crop rotation are just two of the factors that impact crop yield. Dr. Fred Below, Professor of Plant Physiology at the University of Illinois, has seen up to 50-bushel differences between hybrids on the same field based on the seven primary factors: Weather, Nitrogen, Hybrid, Previous Crop, Plant Population, Tillage and Growth Regulators.

    Remember, the potential for next year’s crop begins when the seed is still in the bag! At Latham Hi‑Tech Seeds, we can help you layer yield and soil data to determine which seed is best suited for certain soil types and management situations. Talk to your local Latham® seed representative about how the Seed-2-Soil® program can help you reach new yield levels!

    Milk-Line Can Maximize Productivity of Milking Line

    Written by Brad Beatty, CCA

    Corn silage harvest is underway in eastern Iowa.  To help ensure the best quality silage possible, watch the crop’s moisture content.

    Optimal performance by dairy cows occurs when whole-plant moisture is between 65 and 70%.  This moisture range also works well to preserve silage quality in horizontal (bunker) silos.  However, corn may need to be chopped a bit drier when stored in up-right silos like Harvestores.  Moisture levels between 60 and 65% moisture can minimize seepage in up-right silos, but research shows that reduced fiber and starch digestion, along with reduced lactation performance, occurs when corn silage is harvested at 60% moisture or below.

    The optimum 60 to 70% whole-plant harvest moisture corresponds closely with when the kernel milk-line has moved from one-half to three-fourths the distance from the kernel’s crown to the tip where it’s attached to the cob.  Click here for information on how to find the kernel milk-line.  

    Once moisture of a hybrid is known, figure a corn plant will lose about 1% moisture daily. Monitor the milk-line to gauge whether the moisture is changing too fast.  It usually takes 12-15 days to go from early dent to 50% kernel milk and another 12-15 days to go from 50% kernel milk to black layer.

    More corn silage harvest techniques are available online at http://corn.agronomy.wisc.edu/Management/pdfs/NCH49.pdf.

    NOTE:  Milk-line and whole-plant moisture can vary between hybrids and across environments.  What Latham® Hi‑Tech Hybrids are working well to make silage in your area?

    Tips to maintain quality in high moisture corn

    You’ve heard it a lot this season. Corn quality. According to the USDA Nov. 24 crop report, Iowa still had 22 percent of its corn crop in the field, South Dakota 60 percent, Nebraska 35 percent, Wisconsin 41 percent, and Minnesota 34 percent.  

    Due to the late harvest, a lot of corn went into the bins wetter than desired, reported Rob Swoboda in the Dec. issue of Wallaces Farmer.

    There are three points to remember:

    1) Getting corn in the bin is only part of the battle; managing the corn to retain quality is the second part.

    2) One can’t expect lower-quality corn to keep well during storage.

    3) It will be harder to blend in low-quality corn in 2010.

    Read more to learn tips about how to maintain corn quality this season.

    Please share tips you use to maintain corn quality.
