What short corn can mean for a farm’s forage program

By Cole Diepersloot, Ph.D., Vita Plus forage specialist and dairy nutritionist

Short-stature corn hybrids are becoming a frequent topic of conversation among dairy producers and consultants. Traits like higher fiber digestibility and less risk for lodging have many producers wondering how these hybrids could fit into their silage programs.

Potential advantages

Current commercially available short-stature hybrids have shorter internodes between the leaves below the ear, making them slightly shorter compared to traditional hybrids. With less stalk between leaves below the ear, short-stature hybrids have a greater leaf-to-stem ratio, which drives greater fiber digestibility. Furthermore, short-stature hybrids reportedly have thicker stalks compared to traditional hybrids, which some have speculated may also contribute to greater fiber digestibility. Short-stature corn hybrids may also have greater grain-to-stem ratios, which would increase starch concentrations compared to traditional hybrids.

Short-stature hybrids are especially promising for regions that experience high winds or intense storms, where traditional hybrids consistently experience problems with lodging. Shorter plants with a thicker stalk would be more likely to stand up to high winds.

The greater nutritive value of short-stature corn hybrids may improve dairy cow productivity. Research from Michigan State University showed that cows fed corn silage made from short-stature hybrids had greater milk yields with no difference in intake compared to those fed traditional corn hybrids. Likewise, research from Italy showed that cows fed the European equivalent of short-stature corn hybrids in the U.S. produced more milk and ate less than cows fed traditional corn hybrids.

A common concern among producers is the potential for lower yields of short-stature corn hybrids. Potential yield drag in short-stature corn hybrids is not well understood at this point, particularly since other agronomic practices may interact with yield potential of both traditional and short-stature hybrids. However, it is worth noting that in the two trials that evaluated short-stature hybrids, overall, those hybrids had yields similar to the conventional hybrids.

Planting and harvesting considerations

Producers looking to strike a balance between silage nutritive value and yields should consult their seed dealers, agronomists and nutritionists to evaluate what hybrids and agronomic practices would best fit their soil types and field conditions, management systems, limitations and production goals.

The leaves and ears of short-stature corn plants will be closer to the ground compared to traditional hybrids. Since leaves have more digestible fiber than the stalk and the ears contain starch that heavily contributes to the energy potential of corn silage, harvesters need to minimize the amount of leaves and ears left in the field. Cutting heights of 6 to 8 inches have been suggested for short-stature corn hybrids to maximize the amount of leaves harvested and make sure no ears are left in the field.

To allow for lower cutting heights, some have suggested using rollers on the acres that will be used for short-stature corn to flatten the ground and push any rocks below the surface of the soil. Planting short-stature corn hybrids on the flattest ground and picking up rocks and tree branches can also help accommodate the lower cutting height.

Final thoughts

Short-stature corn hybrids are a promising technology that has the potential to improve silage quality in some corn silage programs. Producers interested in short-stature corn hybrids should work closely with seed dealers and consultants to identify the best strategies to implement these hybrids into their silage programs. If possible, testing hybrids on a portion of their total ground planted in corn to evaluate initial performance is advised while also watching hybrid performance trials to compare agronomic factors and performance potential.
