Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...

Field investigation of glucosinolates and morphological traits in mitigating Psylliodes chrysocephala larval infestation through crop varieties and companion planting

open access: yesPest Management Science, EarlyView.
Genotype and cropping system influenced oilseed rape ecophysiological traits, including glucosinolate compounds (glucoraphanin, glucobrassicanapin, and butyl‐glucosinolates) and biomass, which were linked to Psylliodes chrysocephala larval infestation, with varietal effects stronger than faba bean companion planting.
