Agronomic responses and botanical composition of warm‐season annual forages managed under contrasting harvest strategies

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Warm‐season annual (WSA) forages enhance the summer forage supply in subtropical livestock systems. The objective of this study was to determine forage mass (FM), nutritive value, nitrogen (N) yield, and botanical composition in 12 forage mixtures managed under two harvest strategies (simulated grazing vs. baleage). A randomized complete block

Evaluation of sunn hemp performance and nutritive value in Maine, USA

Grassland Research, Volume 5, Issue 2, Page 112-118, June 2026.
Abstract Background Sunn hemp (Crotalaria juncea L. and Crotalaria ochroleuca G. Don) was evaluated as a warm‐season legume to mitigate the “summer slump” in Maine's forage production caused by heat and moisture deficit stress. Methods This study compared three cultivars: “Crescent Sunn,” “Loei,” and “Red Mini,” at 60 and 90 days after seeding over the

The Effect of Summer Cover Cropping on Soil Health Is Limited by the Quantity of Carbon Inputs in a Winter Dominant Low Rainfall Environment

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The effects of summer cover crops on cash crop yields and soil health in semi‐arid cropping systems in southern Australia remain largely unexplored. A study was conducted in Western Australia to investigate cover crop impacts on soil carbon and nitrogen cycling, soil water, and mineral nitrogen (N) and cash crop yield.

Response of cereals to intercropping with non‐food crops in tropical and subtropical regions: A meta‐analysis

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Intercropping cereals with non‐food intercrops (NFICs) provides a means to enhance cereal productivity while providing additional benefits such as improved soil health or forage production. We conducted a meta‐analysis to investigate the effect of NFICs on cereal yields, cereal nitrogen uptake, and striga (Striga spp.) infestation, using 874 ...

Grazing and cover crop effects on cover crop biomass and crop productivity during transition to organic production

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract We conducted a 4‐year organic transition field study to evaluate the effects of objective‐based cover crop mixtures and grazing on cover crop and forage biomass, residue, and carryover effects on the yield of the first organic certified crop.
