Pulse Agronomy

The Pulse Agronomy Team aims to increase the acreage and diversity of pulse crops grown in Colorado and around the world. Our intent is that by increasing pulse acreage we will advance environmental outcomes including:

  • Improved soil health
  • Reduced water use
  • Diminished demand for fertilizers and pesticides

What is a Pulse Crop?

Pulse crops are plants from the legume family that are harvested for their dried seeds. Pulses include dry beans, peas, and also chickpeas or garbanzos, cowpeas or black-eyed peas, and lentils. Pulses do not include legumes harvested fresh or used as cover crops or forages.

Where We Work in Colorado

We do research in partnership with scientists at many of the Colorado Research Centers including Grand Valley in Fruita, Rogers Mesa in Hotchkiss, and Southwestern in Yellow Jacket.

We also partner with the USDA Agricultural Research Service’s Central Great Plains Research Station in Akron, CO.

Expert Collaborations

Nutrition Collaborations

We are collaborating with nutrition experts like Henry Thompson and Ph.D. students Chelsea Didinger and Tymofiy Lutsiv to increase pulse consumption to improve human health.  

Agricultural Economics Collaborations

We collaborate with agricultural economists, Martha Sullins and Ph.D. student, Babatunde Ojetunde to quantify and expand market opportunities for pulses in order to connect production with consumption.
