www.sare.org publications polyculture-and-reservoir-ranching paddlefish Paddlefish Paddlefish, closely related to sturgeons, are filter feeders throughout most of their lives and the only members of the family Polyodontidae on the continent (4). Paddlefish have a mostly cartilaginous skeleton guaranteeing no bones in the meat. Paddlefish grow rapidly, up to 0.75 pounds/month, and can be easily harvested by seining or gill netting. Paddlefish […]

Meetings with Maryland and Delaware producers of potatoes and other vegetable crops led to the selection of 12 three-year rotational sequences for evaluation in small plots and six three-year rotations […]

Castor bean and the RKN-resistant soybean ‘Manokin’ reduce RKN populations and root galling. However, only sorghum sudangrass reduces RKN and also root-lesion nematode. In addition, incorporation of poultry litter […]

The soybean cv. ‘Manokin’ (maturity group late IV-S) has resistance to RKN. Annual cropping of ‘Manokin’ resulted in consistent reduction in RKN detected in soil assays and less root galling […]

Additionally, reductions in soil-borne and foliar disease may result from cover crop use. Nematode-suppressive cover crops provide the additional benefit of nematode disease suppression. Two non-host cover crops that […]

Sampling soil in the spring is not reliable because few nematodes may be detected even in fields where the risk of potential damage is high. This is probably because inadequate degree-days have accumulated during the spring for nematode reproduction to occur. Samples […]

Genetic markers that are associated with phenotypic traits are often referred to as quantitative trait loci (QTL). The presence of QTL […]

The differences in grass and sedge stubble heights observed between these treatments would be economically important for many public […]
