[Video shows a tractor in a field. Ryan Van Roekel, Crop, Soil and Environmental Sciences, University of Arkansas Division of Agriculture.] Hi I’m Ryan Van Roekel. I’m a Ph.D. graduate student with crop, soils and environmental sciences. We’re out here today around Newport, Arkansas. We’re going to planting one of my strip trials. [This research was funded in part by Pioneer Hi-Bred and the Arkansas Soybean Promotion Board.]
We’re looking at the maximum yield of soybeans. Doing this maximum yield research is to really increase soybean yields in Arkansas overall. We’ve got a growing population. Demand for soybeans is higher than ever. And what we’re trying to do is to find some different ways that Arkansas farmers can increase their soybean yields. [Video shows someone placing flags on rows in a field.]
A couple of things we are doing differently here to help our yields is planting very early and using narrow rows. This field also has been managed for higher yield levels, higher fertility. There’s chicken litter out here as well as conventional fertilizer. The seed we’re using is also treated and inoculated to help potentially boost our yields that way. [Video shows a tractor drill planting in a field. This field has been cotton for the past four growing seasons. Researchers are hoping for a yield boost from the rotation.]
You may notice we are planting with a drill today. One of the things we’re doing in pursuit of maximum yield is looking at narrower rows as opposed to a single row 38-inch planter. Getting these plants closer together within the rows will get us a faster canopy, better radiation use efficiency. We’ll be able to spread the plants out within the rows well.

A couple of things we’re doing different with this maximum use research is very early planting. Today is March 29th, but it’s about 80 degrees and the long term forecast looks very warm as well.
We feel that by planting earlier, we can get the soybeans to flower earlier and longer and potentially get a better pod set and increase our yields that way.
[Ryan Van Roekel] As we compile some of these research, we will be releasing them on Arkansascrops.com. We will also be going around to different grower meetings in the fall and throughout the spring and& sharing this information as we learn a little bit more about the maximum yield of soybeans.
