Planting Date and Seeding Rate Effects on Sunn Hemp Biomass and Nitrogen Production for a Winter Cover Crop [PDF]
International Journal of Agronomy, 2011 Sunn hemp (Crotalaria juncea L.) is a tropical legume that produces plant biomass and nitrogen (N) quickly. Our objectives were to assess the growth of a new sunn hemp cultivar breed to produce seed in a temperate climate and determine the residual N ...

Managing cover crop mixtures over a decade via species replacement and seeding rate adjustment
Agricultural & Environmental LettersCover crop mixtures provide ecosystem services, but species’ relative abundance in mixtures is challenging to manage. We report on an 11‐year experiment where our main objective was to use species selection and seeding rate adjustments over time to ...

Finding the right mix: a framework for selecting seeding rates for cover crop mixtures [PDF]
Ecological Applications, 2021 AbstractCover crop mixtures have the potential to provide more ecosystem services than cover crop monocultures. However, seeding rates that are typically recommended (i.e. seeding rate of monoculture divided by the number of species in the mixture) are non‐optimized and often result in the competitive species dominating the mixture, and therefore ...

Seeding Rates and Productivity of Broadcast Interseeded Cover Crops [PDF]
Agronomy, 2020 Broadcast interseeding cover crops into corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) instead of drill-planting after harvest extends the cover crop season and improves productivity, but establishment can be insufficient. Our objectives were to find broadcast seeding rates that result in maximum spring biomass and N uptake.

Agronomy, 2021 The effects of drill and broadcast planting methods on cover crop biomass production depend on various environmental and operational factors. We investigated whether drilling and broadcasting result in different amounts of biomass production by crimson ...

Seed size variability has implications for achieving cover cropping goals
Agricultural & Environmental Letters, 2022 It is common to use mass‐based units (e.g., kg ha–1) to describe cover crop seeding rates. However, this convention obscures important information about seed size and resulting plant density in the field, which may be linked to cover crop performance and

Agronomy Journal, 2023 AbstractCover crops decrease nutrient leaching from high‐input cropping systems and improve soil quality. In Iowa, cereal rye (CR, Secale cereale L.) is the most adopted species due to its winter hardiness, high biomass productivity, and low cost. Field management of CR is still not completely understood, and as its adoption brings more complexity to ...
