"Wild bee visitation unaffected by disparate nectar phenotypes in a sunflower inbred line population" with Dr. Jarrad Prasifka.
Bees are important pollinators for sunflowers. But, just like humans, they also have preferences, which means it's important for sunflower breeders to breed the kinds of sunflowers that bees like best. In this episode, Dr. Jarrad Prasifka joins me to discuss sunflower nectar and how much it affects wild bee preferences for sunflower lines.
Tune in to learn:
·         How sunflower lines are bred
·         How researchers check for bee preferences
·         How nectar phenotypes affect wild bee preferences in sunflower
·         Which other factors affect wild bee preferences in sunflower

"Mechanical management strategies improve corn production in organically managed living mulch systems" with Ben Brockmueller.
Organic farming is a rich and rewarding challenge for farmers, but without the use of herbicides and other conventional methods, weed suppression can be a problem. Cover crops functioning as living mulches can be one way to overcome this challenge, but what works in one crop may not necessarily work in another. In this episode, Ben joins me to discuss cover crop management in corn as a means of weed suppression.
Tune in to learn:
·         What a living mulch is
·         What challenges farmers face moving organic practices between soybean and corn
·         Which methods most effectively suppress cover crops without killing them
·         What can help close the yield gap between living mulch and conventional systems

"Synthesis, function, and genetic variation of sorgoleone, the major biological nitrification inhibitor in sorghum" with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao
When we fertilize our crops, some of the nitrogen from that fertilizer gets converted into different forms through processes called nitrification and denitrification. When non-plant available forms of nitrogen exit the soil through water or as gas, it's a serious environmental problem. Thankfully, plants have some pretty nifty ways to prevent nitrification, such as biological nitrification inhibition or BNI, a process that manages the bacteria that cause nitrification. In this episode, Sakiko, Bill, and Guntur join me to discuss sorgoleone, a product of sorghum roots that plays a key role in the BNI process.
Tune in to learn:
·         What sorgoleone is
·         How it helps
·         What challenges breeders face in increasing it
·         What challenges researchers face in moving this research out into farms

BNI consortium conference: JIRCAS organizes International BNI-consortium meetings in Tsukuba, Japan, every two years. The next BNI-consortium meeting will be in the first week of December 2026. Most BNI-researchers working with JIRCAS BNI-team are invited for this meeting along with researchers who wish to enter into this research and establish collaborative linkages with other members of this group.

We're trying something a little bit different. In addition to our regular episodes with Abby, we'll be adding a monthly bonus episode with Jim Cudahy, the CEO of the Societies. In this first episode, Jim has a chat with the three Society presidents, discussing current challenges and opportunities for the Societies, including ways that members can get the most out of our programs, but guests will vary a lot from there! Please give a listen and let us know what you think. If there are specific guests or topics you want us to cover, let us know!
