The tropical legume Tropic Sun' sunn hemp (Crotalaria juncea L.) may have potential as an alternative legume cover crop or as forage for cattle in southern temperate regions. This study determined dry-matter production, chemical composition, and N release from sunn hemp residue under conventional and no-tillage systems as might be used in corn (Zea mays L.) production. Sunn hemp was sown in mid-August and mowed in early December on a Norfolk sandy loam (fine-loamy, siliceous, thermic Typic…

Sunn-hemp utilized as a legume cover crop for corn production

Tropic Sunn' sunn-hemp has potential to be utilized as an alternative to winter legumes for ground cover and as an N source for a subsequent corn crop in the Southeast.

Potential for Using Sunn Hemp as a Source of Biomass and Nitrogen for the Piedmont and Coastal Plain Regions of the Southeastern USA

The tropical legume sunn hemp (Crotalaria juncea L.) could be a valuable green manure/cover crop for vegetable producers in the southeastern USA because of its rapid growth and large N 2 fixing

Cotton production in rotation with summer legumes.

Sunn hemp has the potential for providing substantial biomass and N for cropping systems on the low organic matter soils of the southeast US and further research is needed on the fate of the N in the residues during the winter for cotton rotations.

AGRONOMY AND SOILS Cotton Production in Rotation with Summer Legumes

Sunn hemp (Crotolaria juncea) is a fast growing tropical legume that can accumulate large amounts of biomass and N in a relatively short period of time during the summer in the southeast US. This

Dynamics of Soil Nitrogen Availability Following Sunn Hemp Residue Incorporation in Organic Strawberry Production Systems

Sunn hemp (Crotalaria juncea L.), as a summer leguminous cover crop, is often grown before fall planting of strawberries (Fragaria ×ananassa Duch.) in Florida. Although sunn hemp has been suggested

Green Manure as Nitrogen Source for Sweet Corn in a Warm–Temperate Environment

A 2-yr field study to evaluate growth and decomposition of sunn hemp, blue lupin, and Cahaba white vetch used as GM to provide N for sweet corn in a reduced tillage system in northern Florida found the practical value of this benefit is low.

Nitrogen mineralization from ‘AU Golden' sunn hemp residue

ABSTRACT The tropical legume sunn hemp (Crotalaria juncea L.) cultivar ‘AU Golden’ has the potential to provide substantial nitrogen (N) to subsequent crops to reduce recommended application rates of

Nitrogen Mineralization of Cover Crop Residues in Calcareous Gravelly Soil

Tropical legumes like sunn hemp (Crotolaria juncea L.) and aeschynomene (Aeschynomene evenia L.) have potential as alternative cover crops in tropical regions. The objective of this study was to
