Hi. I’m Ryan Van Roekel , Ph.D. candidate at the University of Arkansas. I’m studying the maximum yield of soybeans under Dr. Larry Purcell. [Video shows a Ryan in a soybean field.]

We’re here today in Fayetteville, where I spend the majority of my time when I’m not at Kip Culler’s farm or out taking measurements in the strip trials in eastern Arkansas.

[Video shows a combine harvesting soybeans.] It’s the beginning of October we’ve competed harvest in out three strip trial locations. The best one ended up being near England, Arkansas, where we had two varieties average 103 and 104 bushels per acre. [Video shows a soybean field (England strip trial - mid-season) and soybean plants with pods.]

At the Newport location, we had one strip go over 100. The best varieties there average 98 bushels per acre.

The weather this year has been very good for soybean yields. The only problem was in Newport they had about three weeks of clouds and rain and we shed some of our pods there. [Video shows a combine coming out of the field and dumping the harvested beans into a truck.]

Now out in Helena, we had a challenging spring with some heavy rainfall and the whole trial was under water for about a week. We almost had to replant.  But still that field averaged 85 bushels per acre, and I really shouldn’t be complaining about that.

Last year in Fayetteville we were able to get up to 115 bushels per acre this year some of the beans look even better. Now the problem is we did this with a tremendous amount of inputs and, essentially, an unlimited budget. The goal with those strip trials we been following was to break a hundred bushels per acre without breaking the bank. [Slide - Identified promising production practices for maximizing soybean yield potential: early planting; planting rows less than 38 inches wide; variety selection; timely irrigation; elevated fertility to match your yield goals; strict weed and insect management.]

Over the last three years of research some of the most promising practices we’ve identified for increasing soybean yield include early planting, in rows less than 38 inches wide, variety selection, timely irrigation, elevated fertility to match your yield goals, and strict weed and insect management.

I’m glad to say we finally reached our 100-bushel yield goal. I would like to congratulate the four Arkansas growers and any others that also get to that mark. s

In this final podcast from me, I’d like to take the time to thank Dr. Larry Purcell for all his help and support in his PhD program, and I’d also like to thank all my grower cooperators for putting these trials on their farm  all their help  and support throughout the year. I’d also like to thank the Arkansas Soybean Promotion Board for funding this research, as well as DuPont Pioneer. And lastly I‘d like to thank the University of Arkansas System Division of Agriculture Cooperative Extension Service for posting these podcasts online, as well as publishing my results.

We’re currently compiling the rest of our data doing an economic analysis.  I hope to have that on soon.

I appreciate your interest in this work following me through these podcasts. Good luck with the rest of the harvest.
