On the cover: Pennycress (Thlaspi arvense L.) is a winter annual weed species that is distributed globally in temperate regions. The possibility of pennycress inclusion in the corn–soybean cropping system in the midwestern United States has garnered increasing attention from farmers. Growing pennycress offers environmental benefits—reducing soil erosion and nitrate leaching, improving water quality, early-season pollinator food, and economic benefits—higher seed oil percentage, increased net profit, crop diversification, and biodiesel/renewable jet fuel production.
