Every corn seed contains the potential to excel, and produce a return or 600 to 700 kernels per ear of corn. An excellent return on investment!
What's the value in one ear of corn? An ear of corn is valued by the number of rows and the number of seeds in each row.
In this example, each ear has 18 rows and 35 seeds per row.
Twenty-nine ears in 17.4 feet (1/1000th of an acre) x (eighteen rows x thirty-five seeds in a row = 630 seeds per ear) = 18,270 x .01162 (one one-thousandth of an acre) = 212.3 bushels per acre.
The addition of one more ear, 30 rather than 29, would add 7 bushels per acre to the harvest.
Did you know the difference between eighteen rows and sixteen rows on the ear is a value of twenty-two additional bushels per acre?
A grower plants an 80-acre field, investing 34,000 seeds per acre with the potential to return 2.7 million ears. Two of the last three seasons his corn planting had a 90% “well-planted” rating.
A 90% planting efficiency rate means 272,000 errors. Accuracy as defined in the planting world….90% is paltry as compared to the 99% efficiency Precision Planting considers an excellent rating.
How do we lose 272,000 ears in eighty acres?
How are ears lost? Skips, doubles, and late emergence. All are planting errors.
A late emerged barren plant is one way, and a skipped plant is another. Failing to put a seed in the ground guarantees the loss of an ear. Using the earlier scenario of planting a rate of 34,000 seeds per acre, failing to plant 1000 seeds each acre (less than 3%) would cause a yield loss of 5.7 bushels per acre You math majors would contest this as being incorrect as the calculation would suggest a 7 bushels per acre loss. The reality is the neighboring plants would utilize the unused nutrients and moisture not consumed by the absent plants to produce a more vigorous stalk and larger ear.
Doubles produce smaller stalks than correctly spaced plants. Sometimes they’ll provide a harvestable ear. A less than full cob misses the 100% return on investment of these two seeds, harvesting approximately 150% of the potential 200%. A double in every 1/1000th (17.4 ft) would produce 1000 doubled plants per acre and would equate to 2.8 to 3-bushel loss per acre. Multi-planted seeds are a planter error, it seems like a small detail, but extrapolated overall corn acres means the loss of some serious money. Poor seed singulation and spacing are deficiencies of the planter.
Consistency is what we want the planter to produce…it can be achieved.
The negative impact to yield by skips or doubles is easily understood, and most planter monitors readily inform us as to their occurrence. It's far more challenging to address the causes of late emergence.
Maximum yield set between the time the seed’s placement in the furrow and the closing wheel comes along to close. From this point on the plant is beginning to set yield, between 4 to 8 leaves.
The V3 stage marks the end of the seed as the primary food source of the plant. It is dependent now on the photosynthetic process and the nodal root system. The soil environment is key to the development of the nodal root system. It’s in these next stages, V4-V6, the plant will determine the number of kernel rows and initiate the uppermost ear and tassel development.
From V6 to V8 the row length is set. There is a six bushels per acre difference in this example. The difference could be from planter issues, running out of nitrogen or heat stress. A seed potential of 40 seed length losing 5 and producing a 35 seed row compared to a 25 seed row potential losing 5 and creating only a 20 seed row is a difference of 6 bushels. When does a seed have its highest yield potential? (when it’s in the bag)
The goal is to find this scene repeated in every field. Consistency is the goal. Consistent spacing...every plant is there and every plant is at the proper distance from the next. Even emergence with every plant at the same stage of development. How do we successfully manage the planting process? How do we control that which is controllable? How do we know what’s happening in each area of the planting process?
Understanding the plant’s life cycle, what it needs to thrive and recognizing the environment we place it in. Things we can control which could affect the seed’s potential.
And most importantly, know what the planter is doing throughout this entire process.
Every aspect of the planter pass needs to be measured and managed but how?
