ALABAMA CORN CHAMPS SHARE PRODUCTION TIPS

Alabama corn champions Henderson Farms in Madison, just below Huntsville, topped the National Corn Growers Association state contest in both the irrigated (305.7 bushels per acre) and the non-irrigated categories (232.7 bushels per acre). The Henderson clan of Mike Henderson along with son Chad Henderson and nephew Stuart Sanderson accomplished the feat on the heavy red north Alabama clay soils. It is so sticky that after a rain you will be several inches taller after walking the field. Chad's son Jackson, who is still in high school, runs the grain carts and helps after school, and this summer will join the farming operation full-time after graduation.

Chad and Stuart are students of the crop, always striving for higher yields and looking at ways to make their farming operation more efficient. Their state winning irrigated yield was with Pioneer 2089YHR on thirty-inch rows with a seeding rate of 40,000.  

UNIFORM EMERGENCE A KEY

Chad says one of the keys to their success was an ideal stand with uniform emergence. He notes, "Three years ago we planted by the date rather than the conditions. The soil was wet and we had sidewall compaction. I don't think farmers sometimes grasp how big a difference there is in plant growth and yield when they plant in less than ideal conditions. I could see it on the combine, spindly stalks and up to 40 bushels difference on the yield monitor, when I harvested these areas in the field. We want all the seeds to germinate and emerge within less of a day, twelve hours would be better."

Chad advises, "You want to make sure your planter is in top-notch condition and you plant in as ideal conditions as possible. Those are free bushels when you do this." Stuart nodded his head in agreement, "We'll wait a little longer to plant if the field conditions aren't ideal and there isn't a favorable weather forecast."

They believe starter fertilizer was another key to their success but are not resting on their laurels. They will fine-tune their starter program this year. This past year they applied three gallons per acre in-furrow of an 8-16-11-2 with micronutrients and seven gallons per acre of 10-34-0 two inches deep and two inches beside the row. This year they will apply ten gallons of 28-0-0-5 and five gallons of 10-34-0 with a micronutrient package in a two-three inches band on both sides of the row two inches deep (half of the mixture on each side of the row).

Chad says, "We have a high phosphorus level in our soils so we are cutting back on the 10-34-0 and increasing our nitrogen and sulfur. We feel like getting enough nitrogen and sulfur out early is important to get that seedling off to a great start but we want to have some readily available phosphorus close to the seedling in our cooler soils in the spring."

Chad says they learn the hard way that not all micronutrients would mix with starter fertilizers and advises growers to do a jar test before mixing any micronutrients with starters.

They applied a total of 300 pounds of nitrogen to produce 305 bushels of corn, an efficiency of less than one pound of nitrogen per bushel of corn. They were able to improve their nitrogen efficiency by fertigating through the irrigation pivot with multiple applications of 28-0-0-5. Their last fertigation application came at tasseling. Stuart notes, "You can't just throw nitrogen out and expect a yield increase. It starts with knowing your soil so you can decide on the right nutrient program. Your soil sample results and weekly in-season tissue samplings are vital to a high yield program."

Their weekly tissue samples was a revelation for them. The two nutrients the tissue samples showed they were short on in their 300-bushel corn was sulfur and magnesium. Their nitrogen to sulfur ratio was also out of balance. A nitrogen to sulfur ratio of 10:1 to 15:1 is best for optimum yields and at ear leaf their nitrogen to sulfur ratio was 18:1 to 20:1, something they plan to correct in 2017.

Chad points out that they are striving to produce 300 bushels on every acre under irrigation. They irrigate by plant water usage and knowing their evapotranspiration. He says, "It is important not to let the plant stress at any stage. Anytime the plant stresses you are potentially losing yield. We plan our irrigation to stay ahead of plant usage."

Stuart warns, "Inputs are not going down, they are steadily going up, so our only option is to increase our yields. We can do a better job of marketing our corn if we can depend on higher irrigated yields. We have the option of taking advantages of weather scares during the growing season and booking more corn."

The adage-an ounce of prevention is better than a pound of cure- is their belief that fungicides are insurance. They may not pay every year but they are a good policy from preventing diseases, such as southern corn rust and northern corn leaf blight, from becoming established and severely reducing yields. They applied Headline AMP at V7-10 and again at tasseling.  Stuart says, "Normally we apply a fungicide to our dry land corn but this year it was burning up and we didn't."

 DRY LAND CORN

Henderson Farms also won the state non-irrigated contest. They recorded a 232.7 bushel per acre yield with Pioneer 1319 with a seeding rate of 28,000 per acre. They only applied 170 pounds of nitrogen on their dry land corn and had an extremely efficient nitrogen use rate of 0.73 pounds of nitrogen per bushel of corn. Besides reduced fertilizer use to match their yield potential on their non-irrigated, they use the same basic production practices as their irrigated corn except weed control.

They ran a do-all in front of their planter so the ground is clean. Their dry land corn was non-GMO so they used Roundup + Dual + Leadoff at burndown and came back with Capreno at lay-by. They had more flexibility with their irrigated Roundup Ready corn. They used the same burndown program, then applied Roundup + Atrazine at preemergence, and followed up with Roundup + Atrazine at V3-4.

Stuart advises, "The key to one post-emergence herbicide application is to start clean and getting the plants to grow fast and shade out the weed. We were fortunate that we got some timely rains after planting and got spectacular emergence and early growth. Another key to excellent weed control is having the sprayer capacity to get over your crop before the weeds get too big to control."

Even with all their yield success, Chad and Stuart see opportunities for increased yields. They are working with Alabama Extension with replicated trials in high yield potential fields to see if they can eliminate the sulfur and magnesium deficiencies and improve yields. They have adopted the 4-H motto of "To make the best, better".
