Effects of the Introduction of Feed Grains Into Mid-South Soybean Production Systems John Orlowski1, Bobby Golden1, Jeremy Ross2, Gene Stevens3, Ronnie Levy4, Clark Neely5, Trent Irby1, and Ronnie Schnell5 1Mississippi State University, 2University of Arkansas, 3University of Missouri, 4Louisiana State University, 5Texas A&M University
Rationale and Justification Midwest: 13-19% yield advantage for corn after soybean. 10% yield advantage for soybean after corn compared to continuous soybean. What is the advantage for corn soybean rotation in the Midsouth?
Rotations
Progress… First rotational cycle complete in 2016 Nematode samples currently being analyzed 2016 soil nutrient samples to LSU soil lab soon Hired Dr. Gurpreet Kaur to work on data analysis, project management
Yield following corn vs. soybean* Corn following Corn Corn following Soybean Difference Irrigated 150 160 + 6.6% Dryland 141 148 + 4.9% + 6.4% + 8.1% Soybeans following Soybeans Soybeans Following Corn 49 52 + 6.1% 33 41 +24.2% + 48.5% +26.8% Soybeans Following Corn Burned Not burned Difference 51 55 + 7.8% *Yields in bushels/acre
Dr. Gurpreet Kaur Ph.D. Soil Science/Agronomy –University of Missouri Advisor: Dr. Kelly Nelson Projects: SOIL WATERLOGGING AND N FERTILIZER MANAGEMENT EFFECTS ON CORN AND SOYBEAN YIELDS EFFECT OF FOLIAR BORON FERTILIZATION OF FINE TEXTURED SOILS ON CORN YIELDS IMPACT OF LONG-TERM PHOSPHOROUS FERTILIZATION ON OLSEN-P AND GRAIN YIELDS IN MAIZE-WHEAT CROPPING SEQUENCE ETC.
Upcoming… Grant contracts still not signed due to delays with USB - Hopefully signed by end of February…hopefully Will be sending out data sheets with 2017 crops Begin work on net returns with Dr. Larry Falconer We will be sending out project seed ASAP
What we need… SOIL SAMPLES!!! ASAP Production inputs for each crop/treatment: Chemicals used Fertilizer applied Field operations Etc.
THANK YOU Any Questions?
