Managing the continuous corn yield penalty with crop and residue management
… of this research was to evaluate and determine management practices that could help relieve the yield penalty associated with production of continuous corn compared to when rotated with soybean. This research encompasses two research areas: What are the effects of hybrid selection, enhanced …

Analysis of Summer Spotlighting for Determining Deer Populations Indices
… has caused game agencies to institute more intensive management programs. Proper management of this species has long been a problem of game technicians. In order to obtain an optimum annual harvest, the technician must be able to determine deer numbers and levels of area use by deer. Despite …

The long-run timber output potential in eastern Virginia
… approximately 9 percent by 2020. As for timber management intensity, the study commences with data on cubic-foot yields for the five major forest types, as related to stand age and stocking. From these data, potential yield, per acre and total, is estimated for each class of forest owner. The …

Innovations in fertilizer use and agronomic management for greater productivity of corn and soybean
… varieties grown under increased levels of management. A steady increase in corn and soybean grain yields have resulted in greater nutrient demands from the soil and fertilizer, resulting in many soil’s nutrient reserves to be drawn down. With the advent of innovative precision agricultural …

The role of early management and hormone replacement therapy in potential heart and lung donors
… leads to donor organ injury. Appropriate donor management is essential to avoid further damage to already injured donor heart and lungs. Hormone replacement therapy with tri-iodothyronine and methylprednisolone in organ donors has been reported to increase the retrieval rate of heart and lungs …

Winter Barley as a Commodity Cover Crop in the Mid-Atlantic Coastal Plain and Evaluation of Soft Red Winter Wheat Nitrogen Use Efficiency by Genotype, and its Prediction of Nitrogen Use Efficiency through Canopy Spectral Reflectance in the Eastern US
To understand the impact of N management on harvestable cover crop systems, seven research trials compared: 1) standard intensive management (SIM) (both fall and spring N application), 2) No fall N, a single spring N application, and 3) Cover N (no N application) effects on winter barley (Hordeum …

Intercropping for food, fiber, and fuel on pine plantations in Virginia and North Carolina
Intercropping is defined as a management approach where two or more crops are planted on the same forested site simultaneously. The advantages of applying this concept on young pine plantations in the south can increase site utilization, reduce weed competition, provide annual or semi-annual …
