A weed calculator developed by an Agricultural Research Service (ARS) scientist tells ranchers the number of additional cows they could raise if they eliminated one or two widespread exotic invasive weeds. Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., created a computer model that predicts weed impacts on forage production. Data for developing the model came from 30 weed researchers working throughout the western United...

In what amounted to a kind of census of sweet corn grown for processing, three years of data from 175 fields in Illinois, Wisconsin, and Minnesota shed light on what works and what doesn't. Along with identifying the most troublesome weeds, the results also revealed some of the more complicated relationships among factors influencing both weed control and sweet corn yield in the Midwest. "Rather than a typical controlled field experiment, this was a large scale approach. We wanted to find out...

Ability of jewelweed to recognize 'relatives' from 'strangers' helps shift resources for growth The concept of altruism has long been debated in philosophical circles, and more recently, evolutionary biologists have joined the debate. From the perspective of natural selection, altruism may have evolved because any action that improves the likelihood of a relative's survival and reproduction increases the chance of an individual's DNA being passed on. Social behavior, kin recognition, and...

2-year study shows pine needle mulch most effective Research scientists at Nova Scotia Agricultural College have been working steadily to find effective organic methods to control weeds in cultivated blueberry crops. One resulting study, published in a recent issue of the ASHS journal HortScience, reported on the efficacy of three organic mulches used on highbush blueberry (HBB) produced under organic production practices. The research team determined that the major factor influencing weed...

Study explores how farmers' practice affects role of gene flow between cultivated sorghum and its weedy relatives Family can be a blessing and a curse, and never more so than in the case of crop plants and their wild relatives. These wild and weedy relatives harbor unique and beneficial genes that may no longer be found in their cultivated siblings, but they also harbor genetic traits that farmers have intentionally selected against in their domesticated brethren. The close genetic...
