Bio-Fuel Switchgrass Yields Are Greatly Underestimated
Energy crop company Ceres has announced that switchgrass can produce substantially more biomass than previously reported and that average yields often used by academics and policymakers to forecast bioenergy economics and environmental benefits may, in fact, be far too conservative.
The company reported that yield results from its nation-wide network of field trials showed that average biomass yields among switchgrass seed varieties tested last season were as much as 50% more than the government's projected yields for 2022.
The highest yield was reported in California, where a Ceres experimental variety produced 19 tons per acre.
Predicted that "through trait development, better genetics and improved crop management practices, we can continue to increase average yields for many years to come."
