Intercropping and Organic Pulses with Clair Keene, Ph.D.

Dr. Clair Keene joins us to talk about both intercropping and incorporating pulses into an organic rotation. At the time of our interview, Clair was the extension specialist in cropping systems at the Williston Research Extension Center where she supported farmers directly as well as conducted research and extension outreach with county agents and other stakeholders. Since that time her title has changed to assistant professor and agronomist at North Dakota State University, but her research interests remain in crop rotation, weed management, cover crops, soil health, organic agriculture, and perennial forages. 

We’re going to talk about the intercropping work Clair has participated in as well as some of her efforts to help farmers that want to transition to organic systems in the state. Clair does a great job of blending the agronomic and economic considerations in this episode. 

“Farmers that have grown chickpea with flax, say that they don't see as much ascochyta in their fields. They don't need to spray as often. So they see it as a really important disease management tool. And so I wanted to do the small plot work. Let's see if we can ideally try to figure out why, why does it work?” - Dr. Clair Keene


Intercropping is the act of growing two different crops that are generally planted and harvested at the same time. We’ve discussed it on a few different episodes in the past, including episode 10 of season one with Lana Shaw, episode 6 of season two with Tony Wagner, and in a special intercropping bonus episode. Intercropping provides benefits such as disease suppression, dry down, and harvestability in some cases. As with everything, it’s going to be very dependent on your situation, but Clair does see potential with the chickpea/flax and the canola/pea intercrop combinations specifically. 


“If we can reduce the need for fungicide use, reduce the number of fungicide applications, that's probably the fastest way to reduce chickpea cost of production or at least that I'm aware of.” - Dr. Clair Keene


This Week on Growing Pulse Crops:

  • Meet Dr. Clair Keene assistant professor and agronomist at North Dakota State University
  • Explore her research involving intercropping with pulse crops and best practices for disease management and ease of harvest
  • Discover additional considerations with regard to organic production

About the Podcast

Growing Pulse Crops
The science and business of farming field peas, chickpeas, and lentils
This show features the latest in research, agronomy, and economics of pulse crops (peas, chickpeas, lentils, etc.).

Demand for these nutrient-dense, high-protein foods continues to grow. There is also interest from farmers to include more pulses into diverse rotations for benefits like nitrogen fixation and soil health.

But the industry continues to face challenges, and we are eager to address these head on. So if you’re a pulse grower or in any way interested in these important crops, hit subscribe and stay tuned for future episodes. We’ll be back with plenty of information about challenges pulse farmers are facing throughout the U.S. and what solutions are working.

Brought to you by the Pulse Crops Working Group with support from the North Central IPM Center and USDA NIFA.
