Black Tarps Over Cover Crops Suppress Weeds in Organic No-Till Vegetable Garden

Âé¶¹app researchers have found that using black tarps and cover crops successfully suppressed weeds in an organic vegetable system, allowing scientists to forgo tilling, which can have deleterious effects on soil.

The research was conducted at the Woodman Horticultural Research Farm, a facility of the NH Agricultural Experiment Station, by Seamus Wolfe, a sustainable agriculture and food systems major, Dr. Richard Smith, associate professor of agroecology, Natalie Lounsbury, a doctoral student in agroecology, and Nick Warren, manager of the agroecology lab.ÌýÌý

UNH Researchers Make Breakthrough in Detecting Most Common Bacteria Contaminating Oysters

In a major breakthrough in shellfish management and disease prevention, researchers at the Âé¶¹app have discovered a new method to detect a bacterium that has contaminated New England oyster beds and sickened consumers who ate the contaminated shellfish. The new patent-pending detection method – which is available for immediate use to identify contaminated shellfish – is a significant advance in efforts to identify shellfish harboring disease-carrying strains ofÌýVibrio parahaemolyticus.

Grasslands Better than Forests at Taking Advantage of Northeast’s Warming Winters

As climate changes, Northeast winters are warming more rapidly than other times of the year. While this may mean favorable growing conditions start earlier in the year, some ecosystems, such as perennial grasslands, can take better advantage of that change than others, such as forests, according to new research from the New Hampshire Agricultural Experiment Station at the Âé¶¹app.

UNH Plant Root Research Aims to Boost Local Nursery Production, Reduce Winter Losses and Costs

Nearly every gardener knows that one of the best strategies in choosing plants is to consult the USDA Plant Hardiness Zone Map, which identifies plants based on how tolerant the plant shoots are to cold temperatures. But plant roots are another story, and they often are less tolerant of sub-freezing temperatures than the shoots of the same plant. For businesses that grow nursery stock in containers, protecting container-grown plants during winter leads to increased labor costs and can cause high losses due to physical damage.

Fifteen years of breeding produces new varieties of squash, pumpkins and melons for a wide market

J. Brent Loy’s cucurbit breeding program at the Âé¶¹app, largely funded by the NHAES, represents the longest continuous squash and pumpkin breeding program in North America. The 54 varieties of melons, squash, gourds and ornamental pumpkin released by UNH during the past 15 years have had a major impact on agriculture in the Northeast. In 2014, the wholesale value of cucurbit seed marketed from varieties with UNH parentage was more than $2 million. The value of farm produce derived from those varieties would be several fold that of seed sales.

UNH Researchers Conduct First Comprehensive Study of NH Oyster Farming

Âé¶¹app scientists have conducted the first study of oyster farming-nitrogen dynamics in New Hampshire, providing the first solid research on the state’s oyster farming industry and the role oyster farms play with nitrogen removal. The research, which was funded in part by theÌý, contributes to a growing body of research on how oysters affect the nitrogen content of estuaries such as Great Bay.
