Cereal rye seeding rate does not affect magnitude of weed suppression when planting green within Mid-Atlantic United States

Abstract In the Mid-Atlantic United States, there is increasing interest in delaying cereal rye termination until after soybean planting (i.e., green). Improved understanding of seeding rate effects needed to balance weed and agronomic management goals. We investigated rates on control crop performance when green complementary experiments two regions. The Pennsylvania experiment was replicated at three site-years Delaware site-years. both experiments, population-level responses were evaluated across four rates: 0, 51, 101, 135 kg ha −1 . also implemented a nitrogen treatment factor (0 34 N ; spring applied). Both showed that integrating fall significantly improved winter- summer-annual suppression compared with fallow control, but no differences total biomass production or found among alternative (51 ). Soybean yield did not differ treatments any studies. These results show reason increase for services decrease reasons population yield) employing planting-green tactics no-till within region States.
