Forage crops for hogs
The data obtained by these investigations would indicate: 1. That alfalfa, rape, rye and corn are the most important forages for hogs and should be contained in every rotation if possible. 2. That corn, shorts and tankage are the best concentrates both for the growing hog and for the breeding herd. …

Biomass Crops in Marginal Lands.
… and land use for bioenergy/industrial non-food crops. Cultivating biomass crops on marginal land unsuitable for food production is consistently proposed as an alternative to minimize iLUC effects about land-use competition for food production, and its adverse effects (direct or indirect) on food …

Improving Uniformity of Potato Crops
Within potato crops some tubers are too small or too large to be marketable. There are economic and environmental incentives to improve uniformity, thereby increasing the fraction of yield that is marketable. The potato crop has a complex, three-tiered population structure consisting of plants, …

Monitoring and management of thrips populations in vegetables, row crops, and greenhouse crops in Virginia
Thrips are pests in a variety of crops and are responsible for millions of dollars in damage worldwide. In Virginia there are a few key thrips species that cause a large portion of damage to both vegetable and floricultural crops. Three prominent pests include Frankliniella tritici (Fitch), …

Crops, pesticides, and honey bee disease
… and disease load, as well as agricultural field crops and disease load. The conclusions of this analysis show that natural areas do not seem to have a strong or significant impact on honey bee morbidity factors. In my analysis, I observe that agricultural land does not have a consistent negative …

Herbicide Carryover to Cover Crops and Evaluation of Cover Crops for Annual Weed Control in Corn and Soybeans
While cover crops are actively growing, they compete with winter annual weeds. Studies were conducted to determine the ability of early planted cover crop monocultures and mixtures and a fall applied residual herbicide to compete with winter annual weeds. Cereal rye containing cover crops provided …

Soil solarization weed control in specialty crops
Soil solarization (SS) is a broad-spectrum soil disinfestation technique for the control of crop diseases, nematodes and weeds. Target soils are tilled, irrigated to field capacity, covered, and sealed with transparent polyethylene (PE) plastic mulch during the hottest part of the year for a period …

Value of Cover Crops in Suppressing Weeds and Protecting Cotton Yields and Likelihood of Residual Herbicide Carryover to Cover Crops
… to investigate the potential for using cover crops to suppress problematic weeds in cotton as well as chemical options for cover crop dessication, and sensitivity of cover crops to residual herbicides were evaluated. No differences were observed for cereal rye biomass production and …
