Crotalaria spectabilis Toxicity in Chickens.

open access: yesExperimental Biology and Medicine, 1960
SummaryConcentrations of 0.05% to 5% Crotalaria spectabilis seed were fed to chicks. All concentrations of the legume were shown to be toxic. Concentrations in excess of 0.3% produced death in all birds within 18 days. When less than 0.2% was fed there was a marked reduction in weight gain.

An energy‐based aggregate stability method is more management‐sensitive than commercial methods in coarse‐textured, subtropical orchard soils

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Aggregate stability impacts important soil functions, including carbon/water storage and soil structure. Macroaggregate stability tests, using rainfall simulation or wet sieving, are commonly used, but microaggregate stability tests may be more applicable to subtropical, coarse‐textured soils.

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

open access: yesCrop, 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

open access: yesGrassland 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

open access: yesJournal 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.
