Researching Drought Tolerance News Reporter With California Ag Today, I’m Tim Hammerich. Jeff Dahlberg recently retired as the director of the UC Kearney Agricultural Research and Extension Center in Parlier. In addition to his administrative duties, he had been doing extensive research with sorghum, a crop he originally became fascinated by as a Peace Corps volunteer in Niger, decades earlier. Dahlberg…. “I do think sorghum will become a much more important cereal crop. Unfortunately, it's not wheat, so it doesn't have gluten. So, it doesn't make a nice gluten bread product, which most people are used to. But it does have other characteristics that make it somewhat unique. So for anyone with gluten intolerance, it's a really nice gluten-free flour.”
