Every year, Otto Farms puts in a test plot for corn varieties. Our limit is 24 and we made it to 21 this year. That’s a lot of seed boxes to empty and refill every 500 feet of planting! We plant 3 varieties on each pass. 4 rows/variety. We couldn’t have picked a better day. Beautiful weather with light winds and short sleeve temperatures.
Below is the lineup of varieties that made it into our plot this year. These are varieties we are planting in our field as well as varieties we would consider planting in future years. Most of the varieties are double stacks meaning that they are roundup and corn borer resistant. We have a couple that add in root worm resistance as well. When the double stack varieties are planted in the field we add an insecticide in the seed furrow to control corn root worm as well as other in-ground insects. Continue reading
Planting as well as applying fertilizer and insecticide.
After the slow/cold start to April, we were pleasantly surprised but the fast warmup of both the air and the soil.
An array of monitors.
April 15, 2016 was our official start date this year for planting corn and by April 23 (due to a rain delay) we had all our corn in except 80 acres. We thought we’d squeeze it the last field before the weather turned against us but to no avail. Now we wait through a week of forecast rains.
Soils were fit for planting and had plenty of moisture available for good germination. We still need to get our pre-emerge herbicide on the fields but that time will come soon enough.
The current rain delay allows us to catch up on other things that get ignored when planting is the priority.

Over the winter we have done intensive data compilation and analysis and have a few updates to the corn guidelines publication. The primary update is on nitrogen application rates for corn following corn and corn following soybean. The updated publication is not finished yet, so this article will serve as the current rate guidelines starting spring of 2016.

We couldn’t have asked for better weather for harvesting our test plot. Yields were very consistent across the plot with yields being similar to our fields.
Fall is the time to evaluate our corn varieties in order to aid in decision making for next year’s planting. Our test plot consists of 24 – 4 row strips planted 600′ long. Walking through the plot prior to harvest helps us learn about the strengths and weaknesses of each variety. This year we looked at how many harvest-able ears we have per acre along with how many of the ears were significantly under sized in our opinions. We also looked at the stalks and how much goose-necking they were doing. This year presented us with some strong winds along with a round of hail. The hail damage to the corn was minimal but the wind definitely put the stalks to the test. Now we wait for the combine and weigh wagon to give us the final results.
Late summer means putting time into maintenance of harvest related equipment. The plastic cups on our grain leg, that handles the wet corn coming in from the fields, were getting brittle. We’ve found a couple of them stuck in various places in our grain system and succumbed to the fact that we needed to replace all 203 cups on the belt. Many of the bolts were rusted to the point where we had to either snap them off through the force of our 1/2″ DeWalt impact wrench or grind them off. After many hours the task was accomplished and we’re on to the next project!
