"Sparse testing designs for optimising resource allocation in multi-environment cassava breeding trials" with Dr. Diego Jarquin

Cassava is an important staple crop around the world, but plant breeding efforts can be slow and difficult with limited plant materials and other resources. In this episode, Diego joins me to discuss how genomic selection might rapidly increase this process.

"Role of biochar made from low-value woody forest residues in ecological sustainability and carbon neutrality" with Dipita Ghosh.

Forest debris can clutter forests, squelch healthy growth, and increase the risks of dangerous wildfires, but open burning these residues can be just as problematic, with increased greenhouse gas emissions, pollution, and, that's right, wildfire risks. Turning forest debris into biochar instead can alleviate a lot of these problems while increasing soil health in degraded regions, but to what degree is biochar useful and how can we get it where it needs to go? In this episode, Dipita joins me to discuss her work on all things biochar.

"Lethal and sublethal effects of novaluron, a novel insect growth regulator, on annual bluegrass weevil, Listronotus maculicollis Kirby, lifestages in turfgrass" with Benjamin A McGraw.

Today we'll be talking to Dr. Benjamin McGraw. Annual bluegrass weevil or ABW is a pest that preys on golf course turf. Novaluron is a new pesticide that may be able to help control ABW, but how does it work and at which life stages is it most effective? In this episode, Benjamin joins me to discuss his work studying novaluron.

"Putting the Soil Health Principles to the Test in Iowa, USA" with Dr. Marshall McDaniel and Hillary Olson

Soil health principles can help guide farmers in best practices for long term soil health and improvement. However, it's important to test these principles across locations and contexts to see how their implementation is actually shaping soil health. In this episode, Marshall and Hillary join me to discuss testing the soil health principles in Iowa and how this might be expanded into further regions.

Tune in to learn:

· What the soil health principles are

· Which soil health indicators are fast or slow movers

· Why it's difficult to weight soil health principles

· What future research is yet to be done

"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
