The Kansas soybean commission is proud to sponsor research that advances our state’s soybean crop through checkoff funds. One notable research project focuses on cultural weed control practices in western Kansas under dryland conditions. This study examined the impact of row spacing and seeding rates on glyphosate-resistant kochia and palmer amaranth interference in soybeans. It also looked to determine how these factors impact grain yields and quality. Findings show that herbicides effectively controlled weed density all around, while in untreated plots a seeding rate of 150,000 combined with 15-inch rows had the lowest observed weed density and a comparable yield to treated plots.
Principal Investigator Andrew Tucker of Fort Hays State University notes that combining an optimal seeding rate with an effective herbicide program should be used regardless of row spacing to optimize grain yields in western Kansas. How does one breed a better soybean? Another notable project led by Dr. William Schapaugh asked this question. He and his co-investigators are looking to release new germplasm varieties to increase resistance dewpoint diseases like soybean cyst nematode, and sudden death syndrome, plus improve seed yield. New varieties are available for commercial production and breeding programs to utilize.
