Test Plot Walk Through

Test Plot Analysis

Dennis logging variety information.

Dennis and I like to walk through our test plot pre-harvest to get a feeling for how varieties are performing ahead of combining them. The rains this year presented a challenge in getting this done in a timely manner. We exited the field with a large amount of mud on our boots.Green husk

While surveying the plot we do a stand count to see what percent of our planted stand put on a harvestable ear. We also look for health problems that are presenting themselves. This will give us an idea of what’s going on in the fields that are planted to a particular variety that’s also in the test plot. If a plant has stalk weakness or ears are already hanging down, then we know that we’ll need to keep a close eye on the field we’ve planted that variety in. If that variety isn’t in the field, we probably won’t consider it for planting another year. This is a great reason to have your own test plot rather than just looking at numbers on paper!broken corn ear

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

Test Plot Evaluation

test plotFall is the time to evaluate our corn varieties in order to aid in decision making for next year’s planting. leaning cornOur 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. 2015 Plot

Test Plot 2015

test plot varietiestest plotApril 28th was test plot day. We have 22 varieties in our plot this year from 6 different companies. About 1/2 the varieties are Roundup/corn borer traited. The other varieties also include at least one root worm trait. No insecticide was put on the corn with root worm traits. Wensman 7320 VT3P was place in the plot 3 times to look for variation from one side to the other.

Corn Test Plot Harvest Day 2013

As we work our way through harvest, one of the events we look forward to is harvesting our corn test plot. A lot of time and thought go into choosing hybrids for this plot. This plot is an extremely vital part of our operation’s decision making process for the next year’s corn varieties.

Because our operation focuses heavily on corn varieties that use hybrids with less insect traits than the companies are pushing, there is little plot data available to help us make decisions on these hybrids. This is a part of our broad plan to deal with corn insect resistance issues. Continue reading

Corn Test Plot for 2013

Test Plot Filling 2Every year we put in our own corn test plot. We enter everything we plant in our fields plus other varieties we’re interested in growing for next year. Our direction has turned from past years back toward Double Pro varieties and applying insecticide as well as Triple Pro corn. We are rejecting Smartstax and similar super varieties with multiple root worm modes of control. With root worm resistance showing up in MN fields, not real far from us it’s time to take control and not follow the seed company mantra of more in seed technology. Bugs are adaptive and will overcome these traits in time. We chose not to apply any insecticide in our test plot this year, even on the non RW corn.

That being said, here is our lineup for the 2013 test plot.
